I have a 1TB External HD

Can i partition it to 500GB/500GB and use one side for Time Machine backups (i like TM) and the other 500GB for Carbon Clone Copy back ups so i can boot from it if ever needed without the 2 interfering with each other?

If so how? :)

Thanks in advance!
 
ahh so it is lol - knew it would be that simple somehow!

problem being now is the back ups are taking hours!

taken an hour so far to back up 200MB :S:S:S
 
It shouldn't be taking so long. Try excluding the drives from spotlight in system preferences.

how do i do that - and what will that mean - spotlight only searches for things on the internal HD not the external?

Do you mean 200GB? The amount you stated should backup in a blink.

nope i mean MB .. i know it shouldnt take that long :(


It took a little while to complete the first back up of the CCC to the second partition of the HD but whilst it was doing that the first partition of the HD which was Time Machine was taking forever! Is this because 2 different sources were writing to different parts of the HD at the same time?

This explains a lot. Writing to 2 different partitions on the one drive at the same time will slow things down considerably.

To exclude a drive from spotlight go to System Preferences > Spotlight > Privacy, and drag the drives to the window. This means they won't be searchable with spotlight, but for backup drives this is a good idea in my opinion. First of all for the improved backup times, but also because otherwise everytime you search for something, you'd end up with duplicate results (in your case triplicate!). Should you ever need to search your backup drives, just remove them from the spotlight privacy panel.
 
Okay great thanks for clearing that up :)

I will remove them later on when i get home :D

Also as you say i dont want triple of everything!
