Déjà Dup

Remote manifest does not match local one

Asked by Richard Downert

Having used Deja Dup for approximately 3 months I have suddenly got the following error message when I try to backup:

Backup Failed
Fatal Error: Remote manifest does not match local one. Either the remote backup set or the local archive directory has been corrupted.

I am backing up manually to an external drive. I am using Ubuntu.

Can you help.

Regards Richard Downer

Hmm.. As a workaround, try moving your local cache out of the way. Open a Terminal (press Ctrl+Alt+T) and type the following:

mv ~/.cache/deja-dup ~/.cache/deja-dup.bak

Then try backing up again. This doesn't answer *why* this is happening, but might provide a way forward at least.

I have just experienced this and can confirm that moving the cache directory out of the way makes it all seem to work again,
I have problems with my desktop locking up (hardware, I think), which I think adequately explains why this is happening to me.

May I suggest that this ticket become an RFE to prevent it from happening in the first place or to recover more gracefully?

I believe it has resulted in skipping at least one week's backup due to me simply dismissing the error message repeatedly. I also notice that my local backup directory has only 0-length files for my last backup 2 weeks ago , so my last valid backup is probably 3 weeks old.

I don't particularly depend on backups, since most of what I care about is pushed to remote git repos anyway and I am able to recover just fine, but this behavior is not particular friendly to novice users.
