Help for CloudBackup, the Mac app that backs up your OneDrive folders to an external drive.

Contact

Write to us at office@xvision.solutions. Please include your macOS version and the CloudBackup version (under “About”) and briefly describe what happened. An excerpt from the “Log” in the app is also helpful.

Requirements

• a Mac with macOS 26 or later
• the OneDrive app for Mac, with the accounts you want to back up set up on this Mac
• an external drive formatted as APFS (in Disk Utility); “APFS (Encrypted)” is recommended

Where the backup is stored

On the destination drive, CloudBackup creates a folder named CloudBackup and inside it one folder per profile, made up of the profile name and an identifier. It contains:

• Current: the current state of your files, readable as usual in the Finder
• Versions: replaced file versions, kept for 30, 90 or 365 days depending on the setting
• Deleted: archived files that were deleted in OneDrive

Files are copied without a proprietary format and can be opened without CloudBackup. Please do not change these folders by hand so that the backup catalogue stays correct.

Restoring files

Open the profile and choose a backed-up file or an earlier version under “Restore”. CloudBackup copies it to a folder of your choice, verifies the copy with a SHA-256 checksum and never overwrites existing files. Neither the source nor the backup is changed.

Why deletions need your confirmation

If a file is missing in OneDrive, CloudBackup does not remove it from the backup on its own. It appears under “Pending Deletions”, where you decide whether it is archived (moved to the Deleted folder) or deleted permanently. This way the backup also protects you against files deleted by mistake.

Files stored only in the cloud

If a file exists only in the cloud, the OneDrive app downloads it during the backup. After successful verification, CloudBackup frees up the space on your Mac again. This requires an internet connection and enough free storage on your Mac.

Offsite backup

CloudBackup backs up to a drive that is usually in the same place as your Mac. An additional offsite backup protects against theft, fire or water damage, for example a second drive kept elsewhere or an online backup service (3-2-1 rule: three copies, two media, one offsite).
