any caution for backing up RAID 0+1 on a mac pro?

[quanqing]

Hi,

I've been enjoying SuperDuper! for years, and now I've got a new Mac Pro with four disks configured as RAID 0+1. A little search on the forum says that RAID 0 or RAID 1 alone may need a bit of effort to get the backup (here I mean dump system to a single external disk and vice versa) correct. I'm wondering if there is anything special with the RAID 0+1 configuration... Can it be done at all? Any precautions and suggestions? Thanks!

There shouldn't be a problem copying from a RAID 0+1 configuration -- which appears as a single volume -- to an external...

Thanks for the instant reply! And how about restore the system disk back from the external disk to the RAID 0+1?

Assuming you've set up the RAID before you copy back, it should copy just fine...
