[QUOTE="toMACsh, post: 1603907, member: 112842"] Time Machine will leave a history of backups on your external drive. When it runs out of space, it deletes the oldest backup. So, the answer to your size question depends on how many backups you want to keep around. TM will backup once per hour by default. You can get an "add-on" application to change that, but cannot change it within TM itself. I have mine set to do backups while I'm having dinner. TM will slow everything down while it is running a backup. With that much to do (750MB) I don't know if it would finish in an hour, so without a scheduler, you'd be backing up all the time, and always feel a drag on performance. [/QUOTE]
