8 Best Encrypted External Hard Drives for Secure Storage in 2027

For a strong balance of storage capacity, familiar setup, and password protection, I’d choose the WD My Passport 5TB as the best overall encrypted external hard drive in this lineup. The Apricorn Aegis Fortress L3 is the standout for buyers who need a hardware-focused, certified security option, while the OSCOO touchscreen SSD is appealing if compact solid-state storage matters more than high capacity. The main tradeoffs are security depth versus simplicity, and capacity versus portability: not every drive here uses the same encryption approach, and WD’s password protection should not be confused with a dedicated hardware keypad. Read on for my comparison of all eight drives, what to check before buying, and which type of buyer each one suits.

Key Takeaways

• Security approaches vary: The Apricorn Aegis Fortress L3 and Aegis Padlock are the clearest hardware-encryption-focused options, while WD models emphasize password protection and backup features.
• The Aegis Fortress L3 is the security-first choice: Its FIPS 140-2 Level 3 designation makes it distinct from the general-purpose WD portable drives, but it offers 2TB rather than the lineup’s largest capacities.
• Capacity leaders are conventional portable HDDs: The WD 6TB and 5TB models suit large archives, but buyers should verify the exact security features of the specific model rather than assume all My Passport drives offer identical protection.
• The OSCOO SSD prioritizes compact solid-state storage: Its touchscreen design gives it a different usability profile from the larger-capacity mechanical drives, though its 1TB capacity is more limited.
• Several WD listings overlap: The 2TB, 4TB, 5TB, and 6TB My Passport options make capacity and included software key points of comparison; the model name alone is not enough to establish equivalent encryption or backup features.

More Details on Our Top Picks

1. WD My Passport Ultra 5TB Portable External Hard Drive, Blue

   

   Best for USB-C 5TB Storage

   View Latest Price

   I’d choose the My Passport Ultra when high capacity and a newer connector matter more than specialist security controls. Its 5TB capacity suits large photo or video libraries, while USB Type-C connectivity offers a more convenient fit for compatible laptops than the standard USB connection on the WD 5TB My Passport in black. The drive also adds 256-bit AES hardware encryption and password protection, so stored files have a layer of protection if the drive is lost. Its metal cover and compact 2.5-inch form factor make it practical to carry, though it is still a mechanical hard drive rather than a fast SSD. Mac owners may need to reformat the Windows-formatted drive, and buyers seeking certified, keypad-based security should look instead at the Apricorn Aegis Fortress L3.

   Pros:

   • 5TB capacity accommodates large backups and media libraries.
   • USB Type-C connectivity provides a useful option for compatible newer devices.
   • 256-bit AES hardware encryption with password protection.
   • Compact 2.5-inch body with a metal cover.

   Cons:

   • Windows formatting may require Mac users to reformat the drive.
   • Mechanical hard-drive storage is less suited to buyers prioritizing SSD-class speed.
   • Does not provide the FIPS validation and physical keypad controls of the Apricorn Aegis Fortress L3.

   Best for: Laptop users with USB-C who need several terabytes of encrypted backup storage for photos, video, and work files.

   Not ideal for: Mac users who want a drive ready to use without reformatting, or security-conscious organizations that need FIPS validation and keypad access controls.

   • Storage capacity:5 TB
   • Encryption:256-bit AES hardware encryption
   • Connectivity:USB 3.0, USB Type-C
   • Interface:USB 3.1

2. WD 5TB My Passport Portable External Hard Drive – Black

   

   Best for Built-In Backup Software

   View Latest Price

   This My Passport is the better fit for buyers who want 5TB capacity plus backup tools, rather than a newer USB-C connection. Its included Acronis True Image software adds backup functions and ransomware defense, a more software-focused package than the USB-C-equipped WD My Passport Ultra 5TB. Hardware encryption and password protection address drive loss, while the slim 2.5-inch design suits travel. The tradeoff is connectivity: this model uses USB 2.0/3.0 and has no native USB-C port, so some newer laptops require an adapter. The supplied data-rate figure is unusually low and should not be treated as a reliable real-world speed claim. Compared with the WD My Passport 2TB, this version gives substantially more storage, but takes the same general approach to security rather than adding a physical keypad.

   Pros:

   • 5TB capacity in a slim portable 2.5-inch drive.
   • Hardware encryption and password protection help protect stored files.
   • Includes Acronis True Image backup software with ransomware defense.
   • 3-year limited warranty.

   Cons:

   • No native USB-C connector, which may mean carrying an adapter for newer devices.
   • USB 2.0/3.0 connectivity is less suited to buyers seeking newer high-bandwidth interfaces.
   • The supplied transfer-rate information is unclear, making performance difficult to judge from the listing.

   Best for: Windows users who want a portable 5TB encrypted backup drive and value bundled backup software with ransomware defense.

   Not ideal for: People who need a native USB-C connection, dependable high-speed SSD transfers, or keypad-based access controls.

   • Capacity:5 TB
   • Interface:USB 2.0 / USB 3.0; compatible with USB 3.1/3.2 Gen 2
   • Form factor:2.5-inch
   • Encryption:Hardware encryption with password protection
   • Included software:Acronis True Image backup software with ransomware defense
   • Dimensions:4.22 x 2.95 x 0.75 inches
   • Weight:7.4 ounces
   • Warranty:3-year limited warranty
   Our verdict

   “Pick this for high-capacity encrypted backups with bundled software if USB-A connectivity works for your setup.”

3. Apricorn Aegis Fortress L3 2TB FIPS 140-2 Level 3 Encrypted Portable Drive

   

   Best for High-Assurance Security

   View Latest Price

   For buyers whose priority is security control rather than maximum capacity, the Aegis Fortress L3 is the standout choice here. Its FIPS 140-2 Level 3 validation, keypad PIN entry, and AES-XTS 256-bit hardware encryption provide a more security-focused design than the password-protected WD My Passport drives. It works across PC, Mac, and Linux without extra software, and its aircraft-grade aluminum enclosure is built for tougher handling. The capacity is only 2TB, however, so the WD My Passport Ultra 5TB is a better match for large media archives. The brute-force defense also carries a serious consequence: repeated incorrect PIN entries can crypto-erase the encryption key, making data unrecoverable. Organizations needing centralized setup may also need to buy the Aegis Configurator separately.

   Pros:

   • FIPS 140-2 Level 3 security validation with AES-XTS 256-bit hardware encryption.
   • Keypad PIN entry, read-only modes, and brute-force defense.
   • Works with PC, Mac, and Linux without additional software or drivers.
   • Aircraft-grade aluminum enclosure.

   Cons:

   • 2TB capacity is lower than the 5TB WD My Passport options in this roundup.
   • Repeated incorrect PIN entries can crypto-erase the encryption key and make data inaccessible.
   • Aegis Configurator for mass configuration is sold separately.

   Best for: Security-conscious professionals and organizations that need validated hardware encryption, keypad PIN access, and cross-platform use.

   Not ideal for: Buyers who need 5TB-class capacity, a lightweight everyday carry drive, or a forgiving access process if PIN entry mistakes are likely.

   • Storage capacity:2 TB
   • Encryption:AES-XTS 256-bit hardware encryption
   • Security validation:FIPS 140-2 Level 3
   • Interface:USB 3.0
   • Compatible platforms:PC, Mac, Linux, and mass storage compliant systems
   • Enclosure material:Aircraft-grade 6061 aluminum alloy
   • Weight:1.1 pounds
   • Rotational speed:5400 rpm
   • Read speed:600 megabytes per second
   Our verdict

   “Choose the Aegis Fortress L3 when validated, keypad-based security outweighs capacity, price-free convenience, and a lighter carry weight.”

4. OSCOO 1TB Touchscreen Encrypted External SSD

   

   Best for Fast, Connected Workflows

   View Latest Price

   The OSCOO takes a different route from the mechanical WD My Passport drives: it pairs hardware encryption and password protection with SSD-class speed and a touchscreen that shows transfer speed, temperature, and capacity. That combination is useful for creators who want quick access to active projects and visible drive status, rather than a large archive drive. Its listed read and write speeds reach 2,000 MB/s and 1,800 MB/s, but those figures depend on a compatible USB 3.2 Gen 2×2 connection; other devices may not reach them. At 1TB, it holds less than the WD My Passport 2TB and far less than either 5TB WD option. The zinc alloy housing, magnetic design, and broad device compatibility add flexibility, while ProRes recording depends on a compatible Apple device.

   Pros:

   • Hardware encryption and password protection in a portable SSD.
   • Listed maximum read and write speeds of 2,000 MB/s and 1,800 MB/s.
   • Touchscreen displays transfer speed, temperature, and remaining capacity.
   • Lightweight zinc alloy housing with compatibility across several device types.

   Cons:

   • 1TB capacity is below the 2TB WD My Passport and 5TB options in this roundup.
   • Maximum listed speeds require compatible USB 3.2 Gen 2×2 hardware.
   • ProRes recording requires a compatible Apple device.

   Best for: Mobile creators and professionals with compatible USB-C equipment who need fast, password-protected storage for active files and projects.

   Not ideal for: People seeking the most storage per drive, users without compatible USB 3.2 Gen 2×2 hardware, or buyers who need certified keypad security.

   • Storage capacity:1 TB
   • Interface:USB 3.2 Gen 2×2
   • Maximum read speed:2,000 MB/s
   • Maximum write speed:1,800 MB/s
   • Security:Hardware encryption and password protection
   • Housing:Zinc alloy
   • Weight:52 g
   • Compatibility:Windows, Mac, iPhone, iPad, Android devices, cameras, and gaming consoles
   • Supported console:Sony PlayStation 5
   Our verdict

   “Choose the OSCOO for a fast, feature-rich encrypted SSD if your devices support its connection and 1TB is enough.”

5. WD My Passport 2TB Portable External Hard Drive, Black

   

   Best for Everyday Personal Backups

   View Latest Price

   This 2TB My Passport is the straightforward pick for personal files when a smaller capacity is enough and the focus is encrypted backup rather than specialist security. It combines password protection and hardware encryption with downloadable backup software that includes ransomware defense. Compared with the 5TB WD My Passport models, it gives up room for larger archives, but may be a more practical fit for documents, music, and a moderate photo collection. Its USB 2.0/3.0/3.1-compatible connection supports a wide range of setups, though this remains a mechanical drive, not an SSD for fast project transfers. The software must be downloaded and installed, and some features may require account registration. For stronger physical access controls, the Apricorn Aegis Fortress L3 adds keypad security and FIPS validation, but at a more specialized level.

   Pros:

   • 2TB capacity suits everyday personal backups and media collections.
   • Password protection and hardware encryption help protect stored data.
   • Downloadable backup software includes ransomware defense.
   • USB 2.0, USB 3.0, and USB 3.1 compatibility supports varied setups.

   Cons:

   • Backup software requires download and installation.
   • Some software features may require account registration.
   • Mechanical hard-drive storage is less suited to fast, frequent transfers than the OSCOO SSD.

   Best for: Individual users who want encrypted backups of documents, photos, and music without carrying a high-capacity 5TB drive.

   Not ideal for: Video creators with large working files, buyers who need 5TB of room, or organizations requiring validated security and keypad access.

   • Storage capacity:2 TB
   • Drive type:Mechanical hard disk
   • Form factor:2.5 inches
   • Connectivity:USB 2.0, USB 3.0, USB 3.1 compatible
   • Security:Password protection and hardware encryption
   • Included software:Device management and backup software
   • Color:Black
   • Warranty:3-year limited warranty
   Our verdict

   “Choose this for everyday encrypted personal backups when 2TB is sufficient and you are comfortable setting up the downloadable software.”

6. Apricorn Aegis Padlock 1TB USB 3.0 Hardware-Encrypted Portable External Hard Drive

   

   Best for Software-Free Security

   View Latest Price

   The Apricorn Aegis Padlock is the security-focused pick for buyers who want PIN access and encryption handled by the drive itself, without installing software or needing administrator rights. Its 256-bit AES-XTS hardware encryption works in real time, while epoxy-sealed circuitry and a brute-force self-destruct feature add defenses beyond a password alone. That makes it more purpose-built for sensitive files than either WD My Passport model, which pairs hardware encryption with backup software and a slimmer, higher-capacity everyday-storage pitch.

   The tradeoff is 1TB of mechanical storage and a physical keypad, which can feel slower to access than a software-based password workflow. Transfer figures in the supplied listing also conflict, so I would not choose it based on a precise speed expectation. Pick this for standalone security; choose the 6TB WD My Passport if capacity matters more.

   Pros:

   • Real-time AES-XTS hardware encryption protects data without relying on computer software.
   • Keypad PIN access works without software installation or administrator privileges.
   • Epoxy-sealed circuitry and brute-force self-destruct add physical tamper resistance.
   • USB 3.0 connects to newer ports and remains compatible with USB 2.0 and 1.1.

   Cons:

   • The 1TB capacity is modest beside the 4TB and 6TB WD My Passport options.
   • Entering a PIN on the keypad may be less convenient than password access through software.
   • The listed transfer figures conflict, making expected performance unclear.

   Best for: People handling sensitive work or personal files on shared computers who need PIN-based access without installing software.

   Not ideal for: Buyers who need several terabytes for a large media library or want a faster, more convenient software-based unlock routine.

   • Storage capacity:1TB (1024GB)
   • Encryption:256-bit AES-XTS hardware encryption
   • Interface:USB 3.0, backward compatible with USB 2.0 and 1.1
   • Drive form factor:2.5 inches
   • Rotational speed:5400 rpm
   • Compatibility:Windows, Mac, Linux
   • Security features:Keypad, epoxy-sealed circuitry, brute-force self-destruct, drive reset
   Our verdict

   “Choose the Aegis Padlock if software-free keypad security matters more to you than capacity and streamlined access.”

7. WD My Passport 6TB Portable External Hard Drive

   

   Best for Maximum Portable Capacity

   View Latest Price

   For buyers who want encrypted storage without giving up a large portable archive, the 6TB WD My Passport offers the most capacity among these three picks. It combines password protection and hardware encryption with Acronis True Image for Western Digital, including backup software with ransomware protection. Compared with the 4TB My Passport, the extra 2TB gives larger photo, video, or project collections more room before files need to be split across drives.

   Its security approach is less specialized than the Apricorn Aegis Padlock’s keypad and tamper defenses, and its mechanical disk is not a solid-state drive. The listed read speed is 110 MB/s, so this is better for portable storage and routine backups than frequent transfers of very large files. Choose it when capacity leads; skip it if physical keypad security or faster solid-state performance is your priority.

   Pros:

   • 6TB capacity accommodates large archives without requiring multiple drives.
   • Hardware encryption and password protection add security for stored files.
   • Included Acronis True Image for Western Digital supports backups and ransomware protection.
   • Slim 2.5-inch portable design is suited to carrying between locations.

   Cons:

   • Mechanical storage is less suited to frequent heavy handling than a solid-state drive.
   • The listed 110 MB/s read speed is modest for transferring very large projects.
   • Password protection and bundled software offer less dedicated physical security than the Apricorn Aegis Padlock.

   Best for: Photographers, video editors, and frequent travelers who want a large encrypted backup drive in a portable format.

   Not ideal for: People who need keypad-based tamper defenses or routinely move large files and prefer solid-state storage.

   • Storage capacity:6TB
   • Drive type:Mechanical hard disk
   • Security:Hardware encryption and password protection
   • Connectivity:USB 2.0, USB 3.0, USB 3.2 Gen 2
   • Read speed:110 MB/s
   • Form factor:2.5 inches
   • Included software:Acronis True Image for Western Digital
   • Compatible devices:Desktop, laptop, tablet
   Our verdict

   “Choose this My Passport if you need the largest portable encrypted archive here and can accept mechanical-drive speeds.”

8. WD 4TB My Passport Portable External Hard Drive, Black, Backup Software with Defense Against Ransomware and Password Protection, USB 3.1/USB 3.0 Compatible

   

   Best for Everyday Encrypted Backups

   View Latest Price

   The 4TB WD My Passport is a practical middle ground: it provides substantial portable storage, hardware encryption with password protection, and Acronis True Image backup software with ransomware protection. That combination suits people who want one drive for files and routine backups rather than the Apricorn Aegis Padlock’s more specialized keypad-led security. Against the 6TB My Passport, this model gives up capacity but retains the same broad everyday role for users whose archive fits within 4TB.

   It connects through USB 3.0 and is compatible with USB 3.1 and older USB 2.0 ports, though older connections can slow transfers. The supplied 100 MB/s transfer rate is a reminder that this mechanical drive is not aimed at rapid movement of huge files. Its security features also rely on password protection, not the Padlock’s physical tamper defenses. Choose it for portable backup convenience, not maximum security or speed.

   Pros:

   • 4TB capacity provides room for substantial photo, video, and document collections.
   • Hardware encryption and password protection secure stored data.
   • Acronis True Image backup software includes ransomware protection.
   • USB 3.0 connectivity is compatible with USB 3.1 and USB 2.0 ports.

   Cons:

   • The 100 MB/s listed transfer rate is limiting for frequent large-file transfers.
   • Mechanical storage is less suited to rough handling than a solid-state drive.
   • It has less capacity than the 6TB WD My Passport and lacks the Apricorn Aegis Padlock’s keypad security.

   Best for: Laptop and tablet owners who want a portable 4TB drive for encrypted file storage and scheduled backups.

   Not ideal for: Buyers with archives larger than 4TB, those seeking keypad-based physical defenses, or users who prioritize fast large-file transfers.

   • Capacity:4TB
   • Interface:USB 2.0 / USB 3.0, compatible with USB 3.1
   • Drive form factor:2.5 inches
   • Encryption:Hardware encryption
   • Transfer rate:100 MB/s
   • Backup software:Acronis True Image
   • Compatibility:Desktop, laptop, tablet, Xbox One
   • Warranty:3-year limited warranty
   Our verdict

   “Choose the 4TB My Passport if you want a portable encrypted backup drive with useful bundled software and do not need 6TB.”

How We Picked

I compared these drives on the factors that matter most when the goal is protecting files: the stated security method, capacity, connection and setup needs, portability, and the usefulness of included backup software. I gave more weight to clearly identified hardware-encryption features and a stated security certification than to broad password-protection wording, since those descriptions do not necessarily mean the same thing. I also treated the touchscreen SSD as a different kind of choice from the mechanical portable drives, with compact solid-state storage as its main distinction.

The ranking reflects the best fit for different buyers, not a claim that every product offers equivalent encryption. The WD My Passport 5TB leads as a general-purpose balance of capacity and familiar use, while the Aegis Fortress L3 ranks highest for a security-first buyer willing to prioritize its stated certification. The other WD capacities and the Aegis Padlock earn places for specific storage or access needs; buyers should check the exact model’s security documentation before relying on it for sensitive data.

Factors to Consider When Choosing Encrypted External Hard Drives

Before choosing an encrypted external drive, decide what you need the protection to do. A password prompt, a hardware encryption system, and a certified security design are not interchangeable features. Your storage habits, recovery plan, and the sensitivity of the files should guide the purchase as much as capacity does.

Match the Security Method to Your Risk

Start by asking what could happen if the drive is lost or stolen. For ordinary personal files, password-protected storage may be enough, but highly sensitive work or regulated data can call for hardware encryption and clearly documented security credentials. Read the manufacturer’s security specifications rather than relying on a listing’s use of the word “encrypted.” Check whether encryption is performed by the drive itself, how access is granted, and what happens after repeated incorrect attempts. A certified security level can narrow your options, but it does not replace good password practices. If you cannot confirm the method for a particular capacity or product revision, treat that uncertainty as a reason to verify before purchase.

Choose Capacity Around Your Backup Plan

A drive that is barely large enough for today’s files can become inconvenient once backups accumulate. Estimate the space you need now, then account for growth and whether you plan to keep multiple versions of files. The 5TB and 6TB WD options in this group favor large archives, while the 1TB and 2TB choices suit smaller collections or more selective backups. Do not equate more capacity with better protection: a large drive still needs a separate backup if its contents matter. If you store a full computer image, allow more headroom than a simple document copy would require.

Think Through Access and Recovery Before You Buy

Encryption can make a lost drive safer, but it can also make forgotten credentials a serious problem. Find out whether the product offers a recovery route, administrator controls, or a documented reset process—and whether resetting destroys the stored data. Hardware keypads and touchscreens can offer a direct access method, yet they may feel less familiar than software-based password prompts. Store recovery information separately from the drive, ideally somewhere protected and accessible to the people who may need it. For a shared drive, agree in advance on who controls credentials and how access will be handed over.

Balance Portability Against Capacity and Drive Type

Portable hard drives generally make it easier to carry a large archive in one device, while an SSD is a natural fit when compactness and solid-state storage matter more. Capacity, physical size, and drive type often pull in different directions, so decide which constraint affects your routine most. If the drive will travel in a bag every day, a smaller unit may be more practical than the largest-capacity option. If it will mostly sit beside a computer, the bulk tradeoff may matter less. Check the connection and power requirements for your computer and intended setup rather than assuming every portable drive behaves the same way.

Separate Encryption From Backup and Ransomware Features

Backup software and ransomware defenses can help with recovery and file management, but they do not automatically prove that the drive’s stored data is hardware-encrypted. Treat these as separate jobs: encryption limits access to protected data, while a backup gives you another copy to restore. A drive connected all the time may be exposed to the same computer problems as the files it holds. Keep an additional copy disconnected or stored elsewhere for important data, and test that you can restore files from it. Before buying, confirm which software features are included with the exact model and whether they work with your operating system.

Check Compatibility and Long-Term Usability

Security features are only useful if you can access the drive reliably on the computers you use. Confirm operating-system support, required applications, connector compatibility, and whether the drive needs reformatting for your preferred file system. Reformatting can affect compatibility with other devices, so plan for computers, media players, and backup tools that may need to read the drive. Test access and recovery on your own setup before moving the only copy of important files onto it. Also consider how long the manufacturer supports its software, especially if a desktop utility is part of unlocking or managing the drive.

Frequently Asked Questions

Is a WD My Passport with password protection the same as a hardware-encrypted drive?

Not necessarily. Password protection describes an access control, while hardware encryption refers to how data is encrypted on the drive; a product listing may not spell out both details. The WD models here are presented with password protection or backup features, whereas the Apricorn options are more explicitly positioned around hardware encryption. Check the exact model’s official security documentation before using it for confidential or regulated files. Do not assume that features on one My Passport capacity or generation apply to another.

Should I choose the Apricorn Aegis Fortress L3 or a higher-capacity WD drive?

Choose based on your primary constraint. The Aegis Fortress L3 is the stronger fit when its stated FIPS 140-2 Level 3 security designation matches your requirements, while a 5TB or 6TB WD drive is better suited to a large archive. Security needs and storage needs are separate decisions, and one product may not satisfy both equally well. If you need both extensive capacity and a specific certification, confirm whether the available model meets your organization’s rules rather than buying on capacity alone. You may also need a second drive or separate backup plan.

Can I rely on one encrypted external drive as my only backup?

No. Encryption can protect access if a drive is misplaced, but it does not protect files from hardware failure, accidental deletion, or damage to the device. Keep another copy on a separate drive or in a trusted backup service, and avoid leaving every copy connected to the same computer. A recovery plan needs more than a locked drive: check that backups complete and periodically restore a sample file. For important data, store at least one copy separately from the main device.

Is a touchscreen encrypted SSD a better choice than a portable hard drive?

It depends on what you value most. The OSCOO 1TB touchscreen SSD is the lineup’s compact, solid-state alternative, while the WD hard drives offer much larger capacities for extensive collections. A touchscreen access method may be appealing if you prefer direct control, but confirm the setup, recovery process, and supported devices before relying on it. Choose the SSD for compactness and its access style, not on the assumption that every SSD is automatically more secure. Choose a higher-capacity hard drive if storing a larger archive is the main job.

How much capacity should I buy for an encrypted drive?

Estimate the size of the files you intend to protect, then add room for future growth and backup versions. A 1TB or 2TB option may suit selected files or a smaller computer backup, while the 4TB to 6TB WD options make more sense for large media libraries and archives. Leave usable headroom instead of filling the drive immediately, since low free space can complicate ongoing backups. If you are uncertain, identify whether you need a complete system backup or only a copy of important folders before choosing a capacity.

Conclusion

My best overall pick is the WD My Passport 5TB for buyers who want substantial storage in a familiar portable-drive format, provided its documented security features meet their needs. For best premium, security-first use, I’d look at the Apricorn Aegis Fortress L3; it is the clearest fit here for buyers who value its stated certification over maximum capacity. The best value by storage capacity is one of the larger WD My Passport models, but compare the exact listing and verify its protection features rather than assuming they match across versions. For beginners, a WD model with a straightforward setup and capacity suited to the files may be easier to manage than a specialized keypad or touchscreen drive. For compact, specific-use storage, consider the OSCOO touchscreen SSD; for hardware-keypad access, the Apricorn Aegis Padlock is the more targeted choice. Choose according to the security method you can verify, the capacity you will actually use, and the backup plan you can maintain.
