Time Machine - Deleting Backups

[svfusion]

Good morning everyone. My time machine drive is full and I was wondering if it is safe to delete the oldest back ups. My concern is, is everything in the oldest backup also backed up on the newest backup? I didn't think TM did entire backups each time. I have tried to research what I could but I can't find an exact answer. Kinda a noob still lol

Thank You

You shouldn't have to delete anything, Time Machine should automatically delete your old backups for you.

This is a snippet from the apple support page.
"Time Machine keeps hourly backups for the past 24 hours, daily backups for the past month, and weekly backups until your backup drive is full."

Your questions should be answered here.

If you need to delete a backup it's best to do it from within Time Machine and not the finder.

To delete a backup do the following:

1. Enter Time Machine
2. Locate the backup you would like to delete by travelling forward/backward in time.
3. Once you find the backup to remove, click on 'Action' in the file window toolbar.
4. From the 'Action' list of choices click on 'Delete Backup'.

This should be pretty easy to do.

Hope it helps!
