I'd start a different config for the tape. Currently you probably
do a cronjob with amdump vtapeconfig, simply comment that out entry and
add an amdump realtapeconfig. That way, if you ever need to do vtape
backups again, you can just uncomment it.

no
What some who have a large holding disk(s) space is to let several dump runs
collect on the holding disk(s) by not putting a tape in the drive. Amrecover,
I'm pretty sure, works with the taped or holding disk dumps. Then insert a
tape and amflush them to tape.

Don't bring them all on line at the same time. Make all your disklist entries
but put a # sign to comment them out. Uncomment a couple each dump. Run
amcheck
with several from each client uncommented BEFORE even thinking about a dump.
Maybe use your vtape config to test drive a client before moving them to the
big show.

Both can share a config. Lots of ways to do the M$ machines, none fully
satisfactory. Samba clients to one or several of your unix hosts, nfs
shares if your M$ boxes are nfs servers (possibly from M$'s free Services
For Unix product - SFU), some windows backup program that writes to a file
and backup that single file/directory with amanda, install cygwin on each
box and install amanda so it looks like a unix host. Many limitations to
backing up M$ boxes, set your expectations low and you won't be unhappy.
