I've been using TM for a bit over a year, and never really needed to use it. I have about 70gb of data on my MBP hard drive, but my external TM drive has bloated to well over 200gb (I only have a 250gb HDD). What would happen if I just went into the Backups.backupdb foler and deleted some of the dated folders? would that be a bad idea? can i just delete the entire thing and start over? I really don't see a use for any of these backups. I've never had to restore a file. I just want to know the best move from here.
