Use at least two backups on different storage types, with one copy kept off-site. For many households, a scheduled backup to an external drive plus a vetted cloud backup offers a practical mix of local recovery and protection if the computer or home is affected. Keep removable drives disconnected between backup jobs, protect copies with appropriate security, and test that you can restore files.
What a dependable backup plan needs
A backup is a separate copy you can recover—not simply another view of the same files. Synchronization can carry accidental deletions or malicious changes across devices, and a network-accessible copy may also be reachable by ransomware. CISA’s Data Backup Options describes the 3-2-1 rule: keep three copies of important files (the working copy and two backups), on two different media types, with one copy off-site. It is a planning guideline, not a guarantee against data loss.
Start by listing the files that matter and where they are stored: computers, phones, removable media, network storage, and cloud accounts. Include data wherever it resides, whether on-premises or in the cloud, as NIST advises in SP 800-209. Then choose backup destinations that do not all share the same failure or access risks.
How external drives, NAS, and cloud backups differ
| Storage type | Useful for | Main risks and checks |
|---|---|---|
| External drive | A local copy you can access without an internet connection. | It can be lost, damaged, or exposed to ransomware while connected. CISA recommends storing it safely and disconnecting it when a backup is not running. |
| NAS or network drive | Centralizing backups for multiple devices on a home or small-office network. | It is network-accessible, not inherently off-site or ransomware-proof. Check version history, deletion protection, and whether the devices being backed up can alter or erase its copies. |
| Cloud backup or storage | Keeping a copy away from the home or office, accessible through the provider’s service. | Recovery depends on service access and connectivity. Check retention, deletion recovery, encryption, account protections, restore or export paths, and the provider’s shared-responsibility terms. Cloud storage and a dedicated backup service may not offer the same recovery features. |
These options involve different trade-offs, not universal restore speeds or costs. Local media may be available without a network connection; cloud recovery depends on connectivity and service access. Compare setup effort, recurring service costs, storage needs, device coverage, and how reliably you will reconnect and rotate removable drives.

Build a practical backup routine
- Map your important files. Note what must be recoverable and its current location, including phones and online accounts. Check that the method you choose actually covers each device and file type.
- Choose two different backup destinations. Keep the working copy and create at least two backups on different storage types, with one off-site. A scheduled external-drive backup paired with a vetted cloud backup is one workable arrangement; a NAS can add convenient network storage but does not replace the off-site copy.
- Schedule backups and secure access. Back up frequently enough for the amount of change you can afford to lose. CISA advises backing up frequently and recommends offline, encrypted copies of critical data in its #StopRansomware Guide. Encrypt backups where appropriate, including in transit and at rest, and protect cloud accounts with strong authentication. CISA’s device data guidance recommends backing up locally stored data to an external hard drive or a properly vetted cloud service.
- Keep recoverable versions. Review version history and retention so an accidental edit, deletion, or malicious change does not immediately replace the only recoverable copy. Confirm how long deleted or earlier versions remain available.
- Disconnect removable drives after the job. Store the drive safely and connect it only while backing up or restoring. A drive left connected may be reachable by ransomware affecting the computer.
- Test recovery. Periodically restore representative files to confirm that copies are available and intact. For critical data or strict recovery requirements, test the full recovery process end to end; NIST discusses such testing in SP 800-209. Keep the instructions and credentials needed to restore without relying on the original computer.
Find the backup approach for your devices
Use the combination that covers your actual devices and separates copies from likely failures. A household with one computer might use its scheduled external-drive backup for local recovery and a vetted cloud backup for the off-site copy. A household with several devices may add a NAS to centralize network backups, while retaining an off-site destination and a copy that the networked devices cannot readily change.
For Windows, Microsoft Support lists external storage devices, network drives, and Microsoft cloud storage as backup approaches. See Choose a backup solution in Windows for current options and instructions; interfaces and included services can change.
