Hey Everyone:


I've got a Late 2011 MBP with a 750 GB Superdrive in it.  I've been using a single time machine drive, but I'm starting to use iMovie and my iPhoto database is getting huge.  So I'm outgrowing my Sugarsync backup space and I'm going to have to start doing my own redundancy.


I've recently bought (2) 3TB Western Digital Externals and here's my plan.


1.  Copy existing TM backup to 3TB drive #1.

2.  Set this drive up as a TM drive.

3.  Format existing 750GB external drive.  Use this for offline storage, like for archived iMovie projects.

4.  Setup TM to include this external drive.

5.  Run initial TM process to 3TB drive #1.

6.  Clone 3TB drive #1 onto 3TB drive #2.

7.  Take (1) 3TB drive to office.


From then on, I'll switch the 3TB drives in and out (probably weekly) to have an offsite backup.


Anyone see any issues with this plan?  I'm a pretty experience PC guy, but I'm fairly new to the Mac world and I'm still figuring things out.  I'd appreciate any advise anyone has.

    I would keep a bootable clone of your entire system on a volume of one of your 3TB disks. Use SuperDuper or CarbonCopy Cloner, update nightly, or weekly.

    You shouldn't back up a backup. Make two independent TM backups to the 3 TB drives.

    Or will TM just skip what is doesn't have access to and backup what it does have access to?

    You don't want to use the 'Sandbox' feature of SuperDuper to create your clone. That feature is used primarily (in my case) to create a test bed.


    You just need to clone your Macintosh HD to where ever you decide to keep your clone. You want the Using to be Backup All Files. The Options During Copy can be set to Smart Update XXXX from XXXX. Your initial backup will take a little longer than subsequent backups as that setting will only backup files that were updated since the last backup.
