Before I ask this question, please take a look at my system layout, just so that you know what I'm dealing with here: (see below for the actual question) System Information: Type: Mac Pro (Early 2009) Internal Physical Drives & Volumes: (A & B) - 4TB striped "Soft" RAID (Composed of Two 2TB Hitachi 7K2000 drives) Volumes: #1 - OS X 10.7.4 main boot partition #2 - Media storage partition #3 - Archive storage partition NOTE: There is no Lion "Recovery Partition" because Apple does not allow a recovery partition for a Lion install that is on a "soft" RAID (despite the presence of non-RAID disks in the machine!). (C) - 640GB Western Digital Caviar Blue drive Volumes: #4 - OS X 10.6.2 emergency partition #5 - Bootcamp partition (Windows 7) #6 - FAT32 partition for copying files between Mac & Bootcamp (D) - 1TB Seagate Barracuda drive Volumes: #7 - Backup partition (used to store disk images of laptop) External drives & volumes: (E) - 4TB "Hard" RAID in Rocstor ArcticROC FW 800 housing (Composed of Two 2TB Western Digital Caviar Green drives) Volumes: #8 - Time Machine partition (backs up all volumes on (A & B)) Questions: • If I update volume #1 above to 10.8, but then I need to restore volume #1 back to 10.7.4 using Time Machine, will I be able to? (I only ask because I have heard people say that you cannot restore from Time Machine onto a volume that exists on a "soft" RAID.) • How would I perform this restore, since I will have neither a 10.8 startup DVD nor a "recovery partition" to boot up from? (Can I boot up from the 10.6.2 partition and do it from there?) Thank you.
