Déjà Dup

format of backup disk

Asked by Andreas Saladin

Hello

External hard drives are mostly formatted with NTFS. Do you recommend reformatting to ext4 before backing up with Déjà Dup?

I read that restoring sometimes to be difficult. How safe is my backup data?

I would certainly not want to loose everything. Do you recommend a second (safety) backup in native format?

regards

NTFS is fine.

While I try to keep issues with restoring to a minimum, they have occurred before. Instances of data being lost for good are rare enough that I don't remember any. Usually restore problems are just in the UI, and can be solved by using the command line. See http://live.gnome.org/DejaDup/Help/Restore/WorstCase for what that would look like.

As for second backups, I would emphasize that backups are ideally just for emergency/disaster recovery situations. It's one of those things you don't want to rely on in any case. The number of backups you want is a matter of managing risk. I think in general, a second backup is unnecessary, but that's just for me and my personal data.

Can you help with this problem?
