Re: [Veritas-bu] netapp NDMP and snapshot backup question
2009-03-31 13:03:18
Wildcards aren't supported, so that
method is out. I'm actually trying to find a way to backup a 6TB qtree
and would *REALLY* like to use wildcards to break it up, but not gonna
happen.
I thought about creating a script, much
like Darren mentioned, but I'd really rather keep it as simple as possible.
If anyone has any suggestions, I'd appreciate
it.

Not that I'm aware of. There appear to be two ways this could occur.
The NDMP host could dump all of them, or NBU could find them back them
up separately.
I don't see any way for the first to happen. 'dump' seems to work
on
only one filesystem, and each of the snapshots act like independent
filesystems. So you can't get it in a single restorable bunch.
The second also seems to not work. I don't know any way to get NBU
to
query the NDMP host and back up everything.
> (2) Is it possible to use wild cards to backup certain snapshots in

Nope. Again, independent filesystems. Because the NDMP server
is just
passing this on to the Netapp dump, you can try this...
netapp> dump 0f null /vol/yourvol/.snapshot/*snap_lun0*
filer> dump 0f null /vol/vol0/.snapshot/*hourly*
DUMP: cannot open /vol/vol0/.snapshot/*hourly*.
DUMP: Dump failed to initialize.
DUMP: DUMP IS ABORTED
That could match multiple filesystems, and dump can't handle multiple
filesystems.

Query the netapp for the list of snapshots. Then put any matching
snapshots into your policy.
ssh <filer> snap list <volume> (or use snmpwalk on slVEntries)
bpplinclude <policy> [ -add | -delete | -modify ] <path...>
