I noticed that it is possible to limit the Quota for the WD_Backup using in the web interface. I did this, however it didn’t affect how much space Time Machine reported as being acessible (it still said I had the whole drive available). Is it possible to use the quota for the WD_Backup user to have it tell Time Machine that only that much space is available? This feature is very important to me because my backups are starting to eat up how much space I can use for my regular files.
The other thing I noticed is that in the time between when I updated to Lion, my backup now needs to do an additional 70GB (my total backup is only ~180GB). At this point, since I haven’t lost anything and it doesn’t seem like I’m able to properly set a quota limit (or limit the size of the time machine partition), I’d like to start over with a fresh time machine backup (I know I lose the abliity to back before today, but the backup will only take up ~180GB instead of the bloated 300+ that it is now). Is there an easy way to clear the Time Machine backup altogether and start over?
