Finally decided on system backup: a 120-GB Maxtor One Touch external hardrive with its Retrospect software.
So far so good -- did an initial total system backup and the first automated update.
On the total system backup, not able to identify individual files on the external hard drive, but when desired, can back up individual files any time and they supposedly replace the same ones okay within the total system backup.
Have backed up some separate files too and they are identifiable and workable by themselves. Supposedly can use the external hard drive just like an internal hard drive.
Using USB 2.0 port although sometimes the Maxtor insists it isn't really fast enough to be 2.0. Go figure.
Questions: Have any of you with similar systems ever had to restore your entire drives? Did that work as advertised? Any problems I should know about?
