OK; I'm using FreeBSD 4.2-STABLE as of 13 Dec 2000. The box doesn't
have much in the way of CPU, but has 3 SCSI host adapters (one for the
OS, one for holding disks, and one for the tape & changer). I'm running
amanda 2.4.2 (as released... well, mostly) on it.

Hmm... what changer script are you using? What happens if you issue
"chio" commands directly (as a user who has "write" access to /dev/ch0)?
(The commands I would use for startes would be "chio info" and "chio
params".)

Ummm... you need to use tar, not dump. tar can read an NFS-mounted
filesystem; dump cannot.

Set up a separate configuration for that. I do something like this, in
that I run the "usual" backups Monday - Saturday, and then on Sunday, I
run a different configuration that does record-no level 0 backups of
everything; the media from this are sent off-site for 2 weeks. Much of
the information is set up to be shared between the configurations (by a
combination of "include" directives & symlinks).
I can send more details if that's not enough (but I thought I had a fair
amount of detail in a message a week ago or so).

Sounds as if you'd need to use a custom changer script to do that,
though my knowledge of the details of the stock ones is pretty limited.
Starting with an existing script that comes close can be helpful.
