Unit quit backing up, box pops up says " Backup Failed, not enough storage space". It used to delete old data to make room for new. Computer is iMac Mojave OS 10.14.4
Make sure its not mentioning not enough space on “source volume” if that is the message that means your computer drive is too full and you need to clear space off your computer.
Otherwise you will need to delete old backups or move on to a new drive and keep this one as an archive.
Thx, it used to automatically delete old backups to make space
Well, can’t figure out how to delete old backups😩
