We have a system running that uses rdiff-backup for its backups. However, the backup partition is out of space, so we'll need to re-examine the situation. We do need a permanent solution, but until that time, we simply need to free up some space on the backup partition.
I have located a number of files that we can remove*, but I wonder how I should do this. The first step would of course be to remove the files from the actual file system. However, next I would need to delete it from the backups (that's where we need the space), but I have no idea how to go about that. Does anybody have an idea how to do this?
