Storing a copy of a bootable backup on a Duo v1

Hi All

I'm running OSX 10.6.8 on a Mac Pro and using Decimus Synk to maintain a bootable backup of my boot drive. The bootable backup is stored on a second physical hard drive in the Mac Pro.

My plan, for extra security is to:

1. use Synk (or SuperDuper/CCC) to copy the bootable backup to my ReadyNAS Duo v1 (Sparc based)
2. keep the Duo offsite

Then, in the event of fire/flood/theft/double disk corruption in the Mac Pro
3. copy bootable backup from the Duo to a new hard drive in the current or new Mac Pro
4. boot from the new drive

My question is, will the copy of the bootable backup remain bootable once it's copied to the Duo or will permissions, resource forks, etc. get altered and render it useless? For clarity, I'd never be trying to boot directly from the Duo, always copying it to an HFS+ formatted hdd in the Mac Pro.

I'm sure this question has been asked before but I've spent a hour searching the forum before posting. Thanks in advance for your advice!

Martin

  • I use CCC for back-ups. I would try cloning the system drive to a sparsediskimage on the duo and try backing up from there.

    Do you have a spare hard disk? I would suggest cloning the system disk, shut the system down, insert the spare disk into a spare bay, restart, clone the diskimage from the Duo to the new disk, shutdown, pull the original system disk and restart. You may have to select the bootable disk when you restart. I used a similar technique when I moved my system disk to a SSD.

    I would not rely on a procedure to work until you have tested it though!
