rdiff-backup woes

Submitted by Peter on Tue Nov 16 2004 09:09 over 5 years ago

Rdiff-backup has been failing with the following: 

Previous backup seems to have failed, regressing destination now.
Traceback (most recent call last):
  File "/usr/bin/rdiff-backup", line 23, in ?
    rdiff_backup.Main.Main(sys.argv[1:])

    assert len(newer_incs) <= 1, "Too many recent increments"
AssertionError: Too many recent increments

It seems that a previous backup failed so rdiff-backup is trying to revert and is failing here: 

    def set_regress_inc(self):
        """Set self.regress_inc to increment to be removed (or None)"""
        newer_incs = self.get_newer_incs()
        assert len(newer_incs) <= 1, "Too many recent increments"
        if newer_incs: self.regress_inc = newer_incs[0] # first is mirror_rp
        else: self.regress_inc = None

Looks like I'll have to delete my old backups and start again, that or spend a few hours figuring out what has gone wrong. It may well be due to me messing up the system time a few weeks back.
