Internal VS external HD backup

[pittster]

Run a 2 GHz Power Mac. I normally use the 2nd hard drive as a backup using Super Duper.

Would like to test how 10.5 runs...

can I install Leopard on the backup drive only, see how it runs/works, and if not happy revert back to 10.4 which would theoretically still be on my other drive?

Is this an ok method, or should I purchase and backup on an external drive (I dont own one as yet, as I normally use the 2nd internal drive)?

Should work either way, though performance will be better on the internal buss.

You can change the startup volume using System Preferences > Startup Disk. This will be come the new default setting (reboots will use the last setting here).

Another, temporary method is to restart, then hold down the "opt" key until a set of possible boot volumes is displayed. Then, select the target and continue to boot.

Just realize, the you won't have a backup during the time that you are testing Leopard if you use one drive for Leopard and the other for Tiger.
