Backup sync

Keep every backup drive in sync with your production

Cards are not the only files in a production. Graphics, music, sound from the mixer, scripts and exports end up on the main drive too – and often never make it to the backups. tuu's backup sync closes that gap.

How the backup sync works

Every minute. tuu compares the production folder on the main drive with each backup drive.
Only what is missing. Files that are not on a backup yet are copied and then verified by checksum.
Never overwrites, never deletes. Nothing on a backup is changed or removed. If a file differs, tuu reports it as a conflict and leaves the decision to you.
Waits for finished files. Files changed in the last 60 seconds are left alone until they are done.
Stays out of the way. While a card is being offloaded, the sync pauses.

Why one-way sync is the safe choice

A two-way sync spreads a mistake to every drive: delete a folder on one, and it disappears everywhere. tuu syncs one way, from the main drive to the backups, and only adds. A file deleted by accident on the main drive is still on the backup.

Part of the offload workflow

The sync runs alongside the verified card offload and the backup to several drives, with the same drives you set up once per project. Setup and details: help.
