Newbie needs advice for Tiger install prep

[dnanian]

If you've used 100GB on one drive and have another drive with only 60GB available, you just don't have the space necessary to do a backup.

What you should do is go buy an external FireWire drive from LaCie, OWC or Wiebetech. For your case, I'd suggest a 250GB unit. Make sure it's FireWire, and don't buy an off-brand drive, as it probably won't support Mac boot.

OK, Once you get that, partition it into a 160GB partition and a second of the leftover to hold the 2nd drive.

Then, use "Backup - all files" -- with "Erase, then copy" or "Smart Update" -- to back up from the first drive to the first backup partition, then do the same for the 2nd drive to the 2nd partition.

Subsequent backups should use "Smart Update".

Does that help?
