This bug just happened on my father's PC and I can provide steps to reproduce:
1. Attempt to back up more files than can be stored onto the backup device 2. Backup fails with "not enough space error" 3. Change the configuration in order to be able to backup 4. Manually start a backup The backup fails with the OP error. Deleting the cache dir does not fix it. As a workaround, I have deleted all *sigtar.gz files from the backup device, and this seems to have fixed it. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to duplicity in Ubuntu. https://bugs.launchpad.net/bugs/875676 Title: Backing up fails with 'IOError CRC check failed'.

In this case it doesn't. I'm quite certain that my backup drive isn't corrupted. (It's a raid5.) I'd be happy to provide any additional information needed. ---------- System information: Ubuntu 11.10 deja-dup 20.0-0ubuntu3 duplicity 0.6.15-0ubuntu2 Logs: deja-dup.log: http://pastie.org/2705320 deja-dup.gsettings: http://pastie.org/2705322 To manage notifications about this bug go to: https://bugs.launchpad.net/duplicity/+bug/875676/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
