Deja Dup restore failure

Asked by jeremy herbert

I have Ubuntu 11.04. I made a backup of my stuff with Deja dup, AT THE TIME I HAD WUBI. NOW I HAVE AN ACTUAL PARTITION, and I am trying to restore it but it is not working. The output is:

Failed with an unknown error.

Looks like you got bit by bug 498933. This means that due to a bug, the previous backup you made has a hole in it, in the form of a missing volume file. :(

Is the backup set shareable? We have not been able to determine what causes this bug yet, and would love more data.

Is the backup set important? It's apparently possible to (mostly) recover from this, but it requires a bit of work and luck. I can guide you through that if you're interested. If so, first thing I would need is any file that ends in *.manifest in your backup location. You can't upload files to questions, so maybe open a bug first.

I actually reviewed the manifest and the files, volumes one and 2 are missing in the backup and the manifest doesn't have a location for them. if i chnage the manifest to not include 1 and 2, will that fix it?

(So I'm looking at this, I haven't gone away. I'm faking the problem you have and seeing if there's a way to stitch the volumes together so as to not notice the missing ones.) You're sure only 1 and 2 are missing?

I haven't had luck so far. I had thought that what you tried (removing the volumes from the manifest) would have worked. I'm still looking for a workaround. But I'm going on vacation next week, so it may be a while.
