Backing up multiple computers to one drive

[jscoonover]

First of thanks, maybe this isn't the place but i just wanted to say i really love SD-thanks for all your hard work!

I have a 300 GB drive that i was about to partition so that i can back up 2 computers an imac G5 (powerpc) and a macbook (intel). Is it possible to format partitions on the same drive differently (GUID and Apple)? If so, how? Or am i asking the wrong question?

Stated another way: I would love to be able have 2 bootable partitions (one intel based and on powerpc based) on the same drive using SD.

thanks for any help!

You'll need to use "Apple Partition Map" to partition if you want to do this; note that Leopard really does not want you to do this with an Intel Mac, though... it's probably better, in 10.5. and later, to use separate drives.

So if I were to have 3 x 1TB FireWire drives connected to my server.

Both RAID'd together to form 3TB worth of accumulative data storage.

Then have the 3TB Drive Partitioned into:

2 x 750Gb (GUID for Intel Mac)
2 x 250Gb (Apple P Map for PowerPC Mac)
4 x 120Gb (GUID for two Intel Mac Laptops)
1 x 80Gb (GUID for Intel Server)

As you may or may not be able to tell, I have 5 Macs here. I'd like to have two backups of each. One SD! Clone, and one Time Machine.

Could this idea be Achievable do you think?

Do I even need to do a full backup clone using SD?
Could Time Machine suffice enough as a Backup (is it bootable / fully restorable in the case of total data loss on the Mac?)

Thanks,

I don't think you can partition a RAIDed drive, Van... and you certainly can't use different partition schemes on a single drive... you'd need to use sparse images.

Ok, Sparse Images are fine then. I thought about not using them, because of the load it takes to mount a large sparse disk image before anything can be actually done with it.

The reason I wanted to partition is because of all the different drives sizes not fitting together very neatly.

Still, do you think an SD! Backup and a Time Machine backup at the same time are worth while? Can both be used to fully backup and restore a system?

[dnanian]

I do think redundancy is a good thing, and the two applications are good at different things as well. Of course, without having a bootable backup (due to the RAID), you lose out on a significant advantage of SD.
