I'm a very excited and happy new iMac owner (Mid 2011, 3.4Ghtz, i7, 8GB)...
I recently purchased a LaCie 4TB (RAID1, 2TBx2TB) 2Big Thunderbolt Drive for the following 2 purposes:
1) Create and Store a "Bootable Backup" of my iMac hard drive.
2) Fast External Storage for all my family's media (RAW photos, Music, Movies..)
However, after much research (as well as some conflicting reports), I'm really confused as to the possibility AND advisability of creating a partition in my RAID1 setup. I initially chose this Thunderbolt drive because of the "safety" of creating a mirrored RAID setup... however, according to the SuperDuper! user manual, it is STRONGLY recommended that any backup be partitioned or on a separate disk altogether from regular storage (i.e. Media).
Now, each time I go to attempt to partition my RAID set using DiskUtility it states in the partition info that "this partition can't be modified. Changing a RAID partition may leave the RAID set unusable." This statement frightens me and keeps me from proceeding past this point..
My LaCie 2Big does not support JBOD. So, is it in fact possible to partition my RAID1 setup or am I stuck with no "bootable backup" on the external drive, in which case I'd be forced to save a bootable backup to DVD's (optical) or find some other alternative??
I should mention that I do have a Time Capsule running regular Time Machine backups, which from my understanding are not "bootable backups" or a clone...
Any assistance is VERY MUCH APPRECIATED, as I'm very eager to implement a decent backup system (including a "bootable backup") as soon as possible.
The LaCie is just sitting there empty in RAID1 right now until I can figure this out and proceed..
Thank you in advance for any help and guidance..
