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.

 

Thanks!

    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.

    Thanks guys.  I've followed both of your sets of advice.

     

    I moved the TM backup from the USB powered passport to drive #1 and took it to work today.  And ran a new TM backup on drive #2.

     

    Then I bought SuperDuper and created a 760GB partition on drive #2 and made a bootable clone of it.

     

    Question:  if I start using my passport drive as external storage and want to include it in Time Machine, will it need to be connected every time that TM runs?  Or will TM just skip what is doesn't have access to and backup what it does have access to?

     

    Thanks again very much for your guys help!

    Yes.

    OK - so I have a basic question about SuperDuper.  I created a clone using "Sandbox - Shared Users" and have successfully booted from it, which is great.  But I'm a little unclear on how this works.  It seems from the Help file that it's not the same thing as a stand alone image of the drive since it shares resources with the source drive. 

     

    My question is this: if my internal drive roasts tomorrow, would I be able to boot from the Sandbox with a new blank drive inside the case?

    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.

    So I've got it all setup now.  I've enabled Filevault and I've encrypted the onboard drive without issue.

     

    However, I've chosen the option to encrypt the TM disk as well.  There's about 750GB on this first drive.  It's been running for about 11 hours now and it's maybe through 20%.

     

    Is this about the expected rate to do this, or do I have something fishy going on?

     

    Thanks and Merry Christmas!

    On another note, is there a way to find the percent complete?  My Time Machine settings window just shows a progress bar, with no number......

  • 9. Re: My New Time Machine Strategy

    Ok, I found the percentage complete by opening the menulet drop down.  At 28 hours, I'm at 47% for a 3TB drive.  And I stopped and rebooted in the middle, at around 24 hours.  I can't say that I think it made much of a difference.

     

    Advice?
