Probably, try putting /mnt/filer/ in the exclude_list.

=20
Ok, so most of my unix clients have multiple local volumes.
=20
I backup "/" and check the "cross mount points" option.
=20
I do NOT check "follow NFS".
=20
in some testing, I've discovered that one client, with an NFS mount from a =
NetApp filer, is backing up the NFS mounted volume.
=20
the only wierd thing I can see as the cause for this is that, it is mounted=
 on a symlink.
=20
ie.
=20
a dir exists called: /mnt/filer
a file exists called /filer, which is a symlink to /mnt/filer.
the volume is then mounted on /filer
=20
if you do a df on the client, you see the volume on /filer
=20
when browsing the backup, you see the symlink FILE called /filer, and you s=
ee the contents of the NAS volume under /mnt/filer.
=20
Is mounting via the symlink tricking NBU into thinking the mount is NOT an =
NFS filesystem?
=20
