My HD crashed and I lost all the data on it but thankfully I use time machine. I successfully restored my system from it and everything is fine. The only problem is that now when my system tries to backup to TM it complains that there is not enough disk space as there is only 20gb free. TM is not continuing my incremental backups from before the crash - is there a way I can tell it to continue backing up from where it left off? Or do I need to delete the old backups and start fresh? I would rather be able to use my previous incremental backups and they are all there on the TM drive.
