The short version

  • They diverge on capability: rustic covers restic format compatibility, Windows Backup covers File History.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

rustic

  • The project is small with a short list of active maintainers, so bus factor is a genuine consideration for software whose job is to still work in five years.
  • It inherits the restic repository format, so design limits in that format, including the cost of pruning large repositories, are inherited rather than fixed.
  • Command names, flags and behaviour do not map one to one onto restic, so scripts and runbooks need rewriting rather than a binary swap.
  • Far fewer people have performed a real restore from it under pressure, and backup software is one of the few categories where being second most used is itself a risk.
  • Alternating between rustic and restic against one repository works but doubles the surface for a version incompatibility to corrupt state, so most operators should pick one and stay with it.

Windows Backup

  • Folder backup goes to OneDrive, and a free Microsoft account comes with only 5 GB of OneDrive storage
  • It requires signing in with a Microsoft account rather than a local Windows account
  • Personalization preferences are not backed up if OneDrive storage is insufficient
  • OneDrive folder syncing through Windows Backup is not available for work or school accounts, and Windows does not remember apps for those accounts
  • Device settings sync for a work or school account only if the organization allows it

Answered from the vendors’ own pages

rustic: Can it read my existing restic repository?

Yes, that is the point of the project. Take a copy and verify before you rely on it, as with any change to backup tooling.

Windows Backup: How much cloud storage do I get with Windows Backup?

Your Microsoft account includes 5 GB of free OneDrive cloud storage. "More storage is available to purchase if you need it" for users requiring additional capacity.

Source
rustic: Should I switch from restic?

Only for a specific reason such as configuration profiles, memory use or cold storage handling. Compatibility means there is no cost to trying and no cost to going back.

Windows Backup: What types of Microsoft accounts are supported by Windows Backup?

Windows Backup works exclusively with personal Microsoft accounts (such as those ending in @outlook.com or @live.com). The service explicitly does not support work or school accounts at this time.

Source
rustic: Is it production ready?

It is used in production by a small community, but it is younger and less exercised than the implementation it is compatible with. Test restores accordingly.

Windows Backup: Can I restore my backup to a different PC?

Yes. When setting up a new device, simply sign in with the same Microsoft account used to create the original backup. "If you have more than one PC backed up, you can select More options and select the backup you wish to restore from."

Source
rustic: Does it support the same back ends?

The common ones, including local, SFTP, S3 compatible storage and rclone. Check the current list before committing to an unusual target.

Windows Backup: How do I delete my backed-up data if I no longer want it stored?

Visit your Microsoft Account Devices page, locate the Cloud synced settings section at the bottom, and select 'Clear stored settings' to delete previously backed-up data from your account.

Source
Windows Backup: Which folders and settings can I choose to back up?

You can selectively back up Desktop, Documents, Pictures, Videos, and Music folders, plus settings including apps, accessibility, accounts, Wi-Fi passwords, personalization, and language preferences.
