Déjà Dup

After rsyncing my backup drive to a new hard drive, I can't back up to the new drive

Asked by Jonathon Hodges

Hi Michael,
It's perhaps not the best way to duplicate my old backup (the drive is failing) to a new drive but I used rsync to make a copy of my whole drive.

rsync -r -n -t -p -o -g -v --progress --delete --ignore-existing -l -D /media/old_backup/ /media/new backup/

I've reconfigured Déjà Dup to backup to the new drive but it fails with a 'Bad encryption key' error. I deleted the key (as suggested in other questions) and re-entered my password (after checking it) but it still gives the same error.

Can you see what I've done wrong?

Kind regards,
Jonathon

No, that's odd. I'm not very familiar with all those rsync arguments, but if the end result is a copy of the files, I would expect it to work. One thing to try is to delete ~/.cache/deja-dup . Maybe the metadata there is getting confused with the new path. That's just a guess though.

Hi Michael,
I tried your suggestion but unfortunately that just takes longer to tell me Bad encryption password.

I also tried deleting both the key and ~/.cache/deja-dup. Same result.

Kind regards,
Jonathon

Hi Michael,
I think I've figured it out. There were three empty duplicity-* files from my last backup set, the manifest, volume and signature file all had zero byte size. After deleting these it worked again. It's possible that deleting the ~/.cache/deja-dup and the password key helped too.

Sorry for the trouble.
