Hi Rich, I asked you a question that you did not yet answer:
Are you interested only in full backups and in the ability to restore single
files from that type of backups?
Or are you interested in incremental backups that _also_ allow you to reduce the
daily backup size but still gives you the ability to restore single files?
I am asking this because there are some backup programs that do not fit into the
list above: The Amanda people e.g. call something "incremental backup"
that does not allow you to restore to an empty disk up to the state of the last
incremental. Amanda in this case suffers from the problem that GNU tar does not
allow you to do a restore on an empty disk if someone did rename directories in
a way that triggers the conceptional problems in GNU tar.
So it seems to be important to me to first find what kind of backup you are
interested in.
Please answer my questions!
Jörg
