Does anyone have any experience using legato networker to back up afs
volumes?

We have built a solution around Legato Networker that is using both full and
incremental dumps using 'vos dump'. The resulting files are put in a disk
pool, from there the files are backed up just as any other files.
The script that does the backup calculates what kind of backup (full, level1,
incremental) should be done based on the volume name and date of the last
backup operation.
The recovery script looks first in the same disk pool whether the required
files to restore a volume are still there. If not, the missing files are
retrieved from tape. We implemented also the recovery of individual
files in a volume (current restriction: one file only, no dirs).
As the recovery does require root privileges and on the other hand a
user should be able to retrieve "his" volumes or files the recovery
should be done in a client server environment.
The software is mostly written in perl. A talk (in german) can be found at
http://www.rz.uni-hohenheim.de/afsws06/vortraege/tagung/Friebel_AFSbackup.pdf

I have now put the complete package into
ftp://ftp.ifh.de/pub/unix/sysadmin/afsbackup/
Most of the site dependencies should have been eliminated by now. The
scripts do however reflect to a certain extent the backup policy at our
site (how many levels of backup, try to backup .backup volumes if possible
etc.) and might not be immediately applicable to other sites.
We are running this style of backup since several years already. Last year
the scripts were modified heavily. Since then these scripts were running
smoothly almost unmodified. There is almost no interaction with users as
they seem to be able to follow the instructions on our web page, which is
