Apple Event: May 7th at 7 am PT

Looks like no one’s replied in a while. To start the conversation again, simply ask a new question.

Can I have several Time Machines?

I have several boot partitions over several disks. Am I allowed to have more than one Time Machine partition - each backing up different drives?

Looks like I can, but I thought I'd check.

17" MacBook Pro 5.2, Mac OS X (10.6.6), G-Tech external hard drives

You can't have more than one Time Machine destination disk active at any one time. You can, however, tell TM to back up as many Mac Extended source disks as you have attached, all to a single destination (provided you have space).

Another option would be to have multiple TM destination disks - which is possible, but you have to manually swap out the backup disks and then tell your TM preferences to use the new destination, which kind of negates the automatic nature of Time Machine.

Is it still the same limit today for Mavericks?


I have 1 x SSD and 3 x HDD, I just want to use one 1TB HD to back up the 500GB SSD, and the 4TB HD to back up the 2TB HD. Possible please?

I would also consider having a clone back up drive (drives are cheap, data is not), and set it to back up the entire HDD.


something like this:

I have a redundant backup in addition to Time Machine, (what if my only drive falls off the table and breaks)

Plus clones are BOOTABLE, which means you can boot from them...big plus and something to consider

Thank you for your suggestion. It's the second time for me that Carbon Copy Cloner was suggested, will give it a try anyway.
