Deja dup deleted the entire backup

[Luca Borrione]

$ uname -a
Linux 3.11.0-14-generic #21-Ubuntu SMP Tue Nov 12 17:04:55 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

$ dpkg -s deja-dup | grep 'Version'
Version: 27.3.1-0ubuntu1

I set deja-dup in order to:
- use an external drive of 500GB
- keep the backups at least 6 months
- backup daily

In the GUI it says clearly: "Old backups will be kept for at least six months or until the backup location is low on space".

Today after I think 6 months from the first backup deja-dup said it was doing a "fresh backup" to avoid corruption.
Then after some time it failed because there was no space left.

I closed deja-dup and checked the drive trough nautilus and with my big surprise the drive was completely empty!
Deja-dup removed the entire previous backup!

That's really, really bad!

Thank you for taking the time to report this bug and helping to make Ubuntu better.

 We are sorry that we do not always have the capacity to look at all reported bugs in a timely manner. There have been many changes in Ubuntu since that time you reported the bug and your problem may have been fixed with some of the updates.

It would help us a lot if you could test it on a currently supported Ubuntu version. When you test it and it is still an issue, kindly upload the updated logs by running only once:
apport-collect 1263960

and any other logs that are relevant for this particular issue including the file /tmp/deja-dup.log after running the appropriate line below and replicating the problem (you may want to scrub the log of any incriminating file names or details):

    DEJA_DUP_DEBUG=1 deja-dup --backup | tail -n 1000 > /tmp/deja-dup.log
