** Description changed: when doing a backup for the first time, dejadup verifies your passphrase by having you enter it twice. on future incremental backups it doesn't need to do this because entering the wrong password will result in the backup failing. with the periodic 'full' backups that happen from time to time, however, any password will be accepted. this can lead to a situation where you accidentally type the wrong password once and are left in a situation where you don't know what you typed and have no way to get your files (or do another incremental backup on top of it). i think this is what happened to me recently. clearly, the fix is to explicitly verify the passphrase is correct when doing a new full backup. this may be a duplicity bug. === Ubuntu deja-dup SRU information === [impact] Users may unwittingly re-set their backup password and not be able to restore their data. [test case] - $ deja-dup-preferences # set up a dummy backup - $ deja-dup --backup # complete first encrypted full backup - $ rename 's/\.2016/\.2000/' /path/to/test/backup/* - $ rename 's/\.2016/\.2000/' ~/.cache/deja-dup/*/* - $ deja-dup --backup # second backup, enter the wrong password - $ deja-dup --restore # try to restore with original password [regression potential] Should be limited? The fix is to delete the duplicity cache files, which ought to be safe to delete. + + It's possible if a full backup is being resumed, we might delete the + current progress. That is a better bug to have than this bug, though. + A more complicated patch would need to be investigated to prevent that. ** No longer affects: deja-dup (Ubuntu Precise) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/918489 Title: duplicity allows bad passphrase on full backup if archive cache exists To manage notifications about this bug go to: https://bugs.launchpad.net/deja-dup/+bug/918489/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
