Description

Duplicity will fail when trying to restore a file from a backup set older than the last one.
The problem is caused by the --extra-clean option used in cleanup-data-duplicity.

Step to reproduce the problem:
  • Configure and run a backup for a week
  • After the week, wait for a full backup
  • Try to restore a file from previous week backup
  • The restore will fail

Workaround

Go to duplicity archive directory, dig into the manifest files and find the tar which contains searched data.
Restore the data from full backup using the tar command.

Possible solution

Remove --force --extra-clean options from cleanup-data-duplicity action.

Test case
Test case is quite hard.
After a week check all old *.sigtar.gz are present inside /var/lib/nethserver/backup/duplicity/<hash> directory.
Try also to list a file from an old backup:

signal-event pre-restore-data
duplicity --archive-dir /var/lib/nethserver/backup/duplicity/  list-current-files file:///mnt/backup/mail --time 8D
signal-event poist-restore-data

VERIFIED

I've tweaked the system date, by moving the clock in the future. Backups occur at 1:00 AM.
