Comment 97 for bug 1217959

Deja calls the duplicity command. Monitors the progress and checks that it
finishes. Try getting the underlying command and manually calling
duplicity. When I last looked at this bug duplicity was performing the
backup job to completion. Backups we're ok. Just this error coming from
deja. After looking at the vala code it looked like a vala async call was
failing.

*Check your backups. Do they work?
*Try the deja debug mode to get logs.

export DEJA_DUP_DEBUG=1
deja-dup --backup > dump

Maybe this helps

I'm wondering whether something like wrapping the Path.build_filename
call located in libdeja/OperationVerify.vala:connect_to_job in a
realpath() would be enough to fix this issue.

Unfortunately I don't know vala well enough to test this idea.

Title:
  'metadata' file not found when creating backup ("Could not restore
  ‘/home/user /.cache/deja-dup/metadata’: File not found in backup"

Status in Déjà Dup:
  Confirmed
Status in duplicity package in Ubuntu:
  Incomplete

Bug description:
  Linux release: Ubuntu 13.04 64bit
  Kernel: 3.8.0-29-generic
  Python: 2.7.4
  Deja Dup: 26.0
  Duplicity: 0.6.21

  Hi. I've tried to do my monthly or so backup recently, but Deja Dup
  crashed after trying to backup a very large file (VM disk with Windows
  7, 50GB or so). I tried to do another one, this time excluding all my
  large VM's. However, now when trying to do a backup I'm getting the
  following error a few seconds after inputting my encryption password:

  Could not restore ‘/home/tom/.cache/deja-dup/metadata’: File not found
  in backup

  I've tried reinstalling both deja-dup and duplicity, purging
  duplicity, deleting deja-dup and duplicity from /home/tom/.cache,
  deleting the backup files on the external drive, deleting it's config
  as described here http://askubuntu.com/questions/53980/how-to-delete-
  all-the-settings-for-deja-dup. I know (well, I have some evidence
  supporting this) that the drive itself isn't faulty as I managed to
  backup my old laptop to the drive using duplicity and it worked fine
  (Fedora 19, deja dup 26.0 I think). I will upload the appropriate logs
  momentarily.
