Best way to backup 2 hard drives

I have 1 250gb Macintosh hd (contains osx, applications, image files, etc), 1 320gb baracuda w/images only, 1 external Western Digi My Book 500gb for backup. I want to backup both internal drives to the backup. I have read all the posts, but am not sure the best way to do this.

From what I understand, my options are:
1- partion the ext hd, and schedule a full (all files clone) backup of the mac hd, then schedule (at another time) another full backup of the baracuda, each to separate partitions on the ext hd.
2- schedule the mac hd (copy all files) to the ext hd, and then schedule for the "same time", a copy "files only" of the baracuda to the ext hd, without a partition.
3- Is there another way? Or is #1 or #2 , the best way?

Thanks,
Ted

The best thing to do is to partition the MyBook appropriately for the two sources. Then, schedule two "Backup - all files" backups from the appropriate source to its corresponding destination.

Schedule them both for the same time, and SuperDuper! will take care of the details of running them back-to-back.

I have almost the exact same setup. A 250 GB internal in my iMac, and an external 320 GB drive with files and photos. I currently don't have enough room on my Maxtor backup HD to backup that 320 GB drive and I'm getting more nervous as each day goes by. I'm looking to get a 500 GB external FW/USB2 drive to backup both drives to.

I'm glad I found this question posted here, as it basically answers my question on the best way to do this.
I assume the main HD backup would be bootable, even though it will be on a partition? I don't think the OS has any trouble with that, but I want to be sure.

That's right, as long as the partition type is correct (GUID for Intel Macs, Apple Partition Map for Power PC or a mix of the two).

Dave,

Elsewhere in the forum you and others have written that Intel Macs can boot from an external drive formatted as APM or GUID. Is GUID preferred? If GUID is used can the external drive be installed internally in an INtel Mac if the internal drive fails?

Also you mentioned naming the partition on the backup the same as the internal drive. Is that generally the best way to do it or is that specific to certain situations?

Thanks,
Cathy

Intel Macs can boot from APM partitioned drives. But Apple's transitioning to GUID, so if you can use GUID, might as well...

Naming the backup the same as the original is usually just done when you need to start from it. It ensures that aliases resolve to the "new" volume rather than the original one when both are present at startup time.
