Card backup

Back up camera cards to several drives at once

One copy of your footage is no backup. A drive can fail, get lost or get formatted by mistake. That is why crews copy every card to at least two drives before the card goes back into the camera. tuu does exactly that, on a Mac or PC, without you watching the progress bar.

Main drive plus as many backups as you need

One read, many writes. tuu reads the card once and writes to the main drive and every backup at the same time.
Separate disks. tuu checks that each drive is its own physical disk, so two folders on one drive never count as a backup.
Space checked first. Free space on every drive is checked before the first byte moves, and tuu shows how many more cards fit.
The same folder tree everywhere. Production, operator and card number, or your own layout per project – identical on every drive.

Every backup is verified

A backup you have not checked is a hope. tuu reads every file back from every drive and compares it by checksum (XXH3, optionally MD5, SHA-1, SHA-256 and more). Only when all copies match does the card turn green. Each card folder gets an ASC MHL manifest and an offload certificate, so you can prove it later – and check the drive again months later with Check drive.

No double work

tuu fingerprints every card. Insert the same card again in the same production and tuu says it is already backed up. Kept shooting without formatting? tuu offers to back up only the new clips. Hidden system files like .Spotlight-V100 and ._ files are left out.

And the rest of the production folder?

Graphics, audio or documents that land on the main drive without tuu are copied to every backup by the backup sync. How the offload itself works: camera card offload for Mac and Windows.
