Nathan,
We use ALL_LOCAL_DRIVES with the allow multiple streams and it
works well for both backups and restores. Because our databases are
backed up using RMAN we exclude database related files during OS backups as we
know we’ll get the required database files during their own backups.
One note of caution regarding the use of ALL_LOCAL_DRIVES if you
are using ZFS on your unix clients and NBU 6..5 or 6.5.1 though. We found
out (luckily) that in 6.5 and 6.5.1 they removed the ability for NBU to back up
ZFS file systems using ALL_LOCAL_DRIVES as the backup selection. Our root
filesystems (on UFS) would back up just fine but it would ignore the ZFS file
systems. This was fixed by an engineering binary in 6.5.1 and I believe
has been addressed in later versions (6.5.2 onwards !!).

Subject: [Veritas-bu] "/" + Cross All Mnt Pts Vs.
ALL_LOCAL_DRIVES
I'm just looking to see what the recommendation out there is
for backing up unix-based servers.
In the past I've always backed up a unix client using
"/" in my selection list and using cross all mount points + exclude
lists. As I was browsing through the Admin guide I read that
ALL_LOCAL_DRIVES could be used on unix-based clients as well.
I'm interested to know how people out there backup their
unix clients. We use cross all mount points so to make sure that an
Admin doesn't create something on a client that needs to be backed up that he
doesn't tell us [backup admins] about.
I'm looking into using the ALL_LOCAL_DRIVES directive with
"allow multiple streams" so I can stream out my unix clients by
filesystem thus getting more i/o throughput by having the backups read from
multiple physical disks at the same time. ... This opposed to using
"/" + NEW_STREAM .. since I don't really know what directories are
actual filesystems. (I don't admin the majority of the clients I backup.)
