On my most recent weekly backup today, Deja-Dup gave me this little love note:
Backup Failed
Invalid data - SHA1 hash mismatch for file:
duplicity-inc.20130124T230054Z.to.20130201T225108Z.vol1.difftar.gpgCalculated hash: 7726f55012e1e26cc762c9982e7c6c54ca7bb303
Manifest hash: 205ecad0a91f8a11967b70d2d3fbc8e4d06231f5
I'm running 12.10 and have been running weekly deja-dup backups since I installed it.
I understand from reading other threads that this is a known software bug that happens when duplicity is interrupted, but most of those other threads are people trying to restore from these corrupted backups.
I've tried deleting and rm-ing the file in question to try again, but I get an error saying the file wasn't found.
My question is, what does this mean for my backups going forward? Did this week's backup work? Will next week's? If not, how can I resolve this error?
I'm not too concerned about the old versions of my files, and even if I need them in the future, I have some disk images saved which I could restore from. So should I just delete everything and start deja-dup from scratch?
Any advice is appreciated.
