Back Up Windows to OneDrive — Real, Versioned, Encrypted
Last updated June 2, 2026
OneDrive folder sync isn't a backup. BackupKit makes scheduled, AES-256 encrypted, versioned backups of any folders to the OneDrive storage you already have with Microsoft 365.
If you have a Microsoft 365 subscription, you already have a terabyte of OneDrive storage. That's an excellent backup target — if you use it as one. BackupKit backs up the folders you choose to OneDrive on a schedule, encrypted, with real version history. That's a different thing from the OneDrive sync client.
Why OneDrive sync isn't enough
OneDrive mirrors the contents of a few specific folders. It's convenient, but it has the classic sync weaknesses: a deletion or a ransomware encryption propagates to the cloud, and anything outside the synced folders isn't protected at all. OneDrive does keep some version history and a recycle bin, but it isn't a folder-by-folder backup with retention policies you control.
- Back up any folder: project directories, a photo archive on D:, app data — not just what's inside the OneDrive folder.
- Keep versioned archives with retention by age or count, independent of OneDrive's own history limits.
- Encrypt client-side so Microsoft stores ciphertext it can't read.
Because BackupKit writes separate, encrypted, versioned archives rather than mirroring live files, an attack that encrypts your working files doesn't poison your backup history. You restore the last clean version in one click.
Set it up
- Connect your OneDrive account in BackupKit (personal or, where policy allows, Microsoft 365).
- Create a backup job. Pick source folders and a OneDrive destination folder.
- Configure AES-256 encryption, a schedule, retention, and optional compression and filters (skip
node_modules,*.tmp, caches). - Activate. Unattended, with failure notifications by email, Telegram, or a tray popup.
Common questions
Yes. Sync handles “same file on every device”; BackupKit handles “a safe, versioned, encrypted copy if something goes wrong.” They solve different problems and coexist fine.
Yes — archives count against your OneDrive storage. Compression and a sensible retention policy keep it in check.
Add a second job to a NAS, FTP server, or another cloud for 3-2-1. BackupKit manages all destinations from one app.
