Re: [rdiff-backup-users] Repair repository

[Dominic Raferd]

After deleting the current_mirror file did you then run rdiff-backup with --check-destination-dir? This performs the actual regression to the previous, hopefully consistent, backup.

Hello,

One of my backup repository seams to be mess up alot. I think the backup have been interrupted multiple time. I do have a very long history for this backup and I don't want to lose it.

First, I encounter "regressing destination" error. So as usual, I've delete the current_mirror. But even then, the backup refused to start with the following exception:

Do you have some good approach to repair a repository ? May I revert the backup destination to a stable point ?
