Feature overview

The Home page shows at a glance whether your files are protected and when the backup last ran. It is both the starting point for common tasks and a status dashboard showing what is protected, where the backup is stored, what comes next, and whether a drive or decision is needed.

For a novice user, the product can be understood as four connected jobs: select, copy, remember, and recover.

  1. Select the files and folders that matter.
  2. Copy them to independent storage.
  3. Remember earlier states instead of keeping only today's copy.
  4. Recover a whole folder, one file, or one older version when needed.

Backup modes​

Back up my files is the quickest path. It offers familiar personal folders, creates version history, and uses an automatic hourly schedule by default. It is the best starting point for most users because it answers the important questions without presenting every advanced setting first.

Custom backup lets you choose any source folders, a destination, retention limits, encryption, and schedule. A backup copies changes in one direction and preserves recoverable versions. Use it for project folders outside the normal Windows locations, several source folders in one backup, or a destination that requires special configuration.

Synchronization keeps locations aligned. Depending on the selected mode, changes can travel in one direction or both directions, and deletions may be propagated. Synchronization is useful for working copies; it is not a replacement for a versioned backup. See Understanding synchronization.

What happens during a backup​

O&O AutoBackup first scans the selected sources to discover new, changed, moved, or deleted items. It compares this state with its recorded backup state and creates a plan. Only the required data is transferred, which is why a later backup is normally much faster than the first.

If a file is open exclusively, a destination is unavailable, or an online-only OneDrive file cannot be fetched, O&O AutoBackup reports the condition. It does not silently turn an incomplete run into a reassuring green status. The next suitable run can catch up.

Protection that adapts​

Scheduled work runs while you are signed in and O&O AutoBackup is active in the notification area. A missed run is caught up later. If a removable destination is absent, the application waits calmly and continues when the correct drive returns. This is particularly useful for laptops: the backup routine can be “connect the drive when convenient” instead of “remember an exact appointment.”

O&O AutoBackup identifies the destination volume, so another disk that happens to receive the same drive letter is not treated as your backup disk. That protects against an easy-to-miss Windows behavior where removable drive letters change.

Runs can wait while the PC is on battery, on a metered connection, or actively in use. These behaviors are controlled under Settings → Autostart. A deferred run is not forgotten; it becomes pending work and starts when the blocking condition clears.

Recovery choices​

The restore view presents the files that existed at a selected point in time. You can restore everything or make a precise selection. Search helps locate a file when you no longer remember its folder. The optional recovery app copied to the destination lets you open the backup on another compatible PC without first setting up your original installation.

For unencrypted backups, current files also remain directly accessible through File Explorer. Encrypted backups must first be unlocked with the password or recovery key; see Restore an encrypted backup.

Plain files by design​

Unencrypted data is stored as regular files rather than compressed into a single archive. No compression is a deliberate design decision, not a missing checkbox. It favors transparency, direct access, and long-term restorability over saving destination space with a proprietary container. Version management and optional encryption add structure where needed; see Backup format.

What O&O AutoBackup does not replace​

  • It is not a system image and cannot rebuild Windows or installed applications.
  • It is not malware protection; it preserves copies but does not judge whether a source file is safe.
  • Synchronization is not automatically backup, because it can propagate unwanted changes.
  • OneDrive is not an independent offline copy of itself.
