Bug Description
I am using Deja-Dup 14.2 on Ubuntu 10.04.
Concerns:
a) DD will not make incremental backups. Whenever a backup is initialized, subsequent to a full backup; DD messages, that it is "cleaning up"; -> removes the backup data; and then signals that it is "creating the first full backup.
b) When the first full backup is completed again; it, about 50% of the time, signals "Backup Finished -> your files were successfully backed up"; OR, in the other 50% of times, DD starts all over with "cleaning up" and removes the backup data; with again signaling, "creating the first full backup; which it starts to do.
c) When a first full backup has supposedly "completed successfully"; if, Restore is run; DD always, shows a message stating "checking for backups -> followed with a subsequent message, "Restore Failed" -> and the backup data again, is deleted.
To Reproduce:
Backups were initialized with directions from Michael Terry as below:
DEJA_DUP_DEBUG=1 deja-dup | tail -n 1000 > /tmp/deja-dup.log1
# Now try to make an incremental backup (which we expect will delete the previous one)
# Note that this line is different than the above one, as we now want the first 1000 lines, not the last 1000
DEJA_DUP_DEBUG=1 deja-dup | head -n 1000 > /tmp/deja-dup.log2
Logs 1 & 2 are shown hopefully. in the attachments.
I highly suspect this is due to bug 881727. It's a bug with duplicity 0.6.16 from the PPA (which in the question that prompted this report, you mentioned you have enabled) which causes good backups to be signaled as incomplete. Which causes Deja Dup to delete them as a waste of space. Which leads to this bug.
