Just out of curiosity but what version of server / client are you running ....
Does the networker client automatically pick up the EXT4 file system (are the
other file systems on the client EXT4)
I don't have a linux box to test this on, but if you did a catch-all backup
that specified the files system types ... does it pick it up automatically ie
instead of using ALL for the saveset try
All-ext3
All-ext4
... and any other filesystem type you might have, I have come across
all-zfs, all-ufs, all-lofs, all-ntfs - has anyone seen a definitive list of
valid files system types?

I actually misspoke in my earlier description. The snapshot mount is actually
*always* present in /etc/fstab:
/dev/sanvg2/bbcontent_snap /bbsnap ext4 defaults,noatime,noauto 1 2
The savepnpc precmd is *not* adding that. It's just generating the snapshot
and mounting it on /bbsnap. The savepncp postcmd unmounts it and removes the
snapshot, but leaves the entry in /etc/fstab.
We did it that way because we thought that would make it easier with NetWorker,
but as we discovered, the "All" saveset still is not including /bbsnap among
the list.
We're guessing that's either happening because of the ",noauto" on the mount
options, which is pretty much required for this scenario, or because the client
may actually be looking at /proc/mounts too and discovering that even though
there's an ext4 filesystem mentioned in /etc/fstab, it's not (yet) mounted on
/bbsnap.
