Why does Time Machine say it doesn't have enough space for a backup? Doesn't it delete older backups?
I have a 1TB LaCie external drive that I've been using for Time Machine for a little over a year. Currently the backup fails because "The backup disk needs 83.92 GB for the backup but only 50.14 GB are available." I thought that Time Machine would delete older backups to make room for new ones. Why doesn't it do that to make enough room on this drive?
