Hi,
I have configured the AdvFS on top of LSM volume. Can I uses the
LSM's snapshot to backup my temp volume created by "volassist
snapstart" & "volassist snapshot" ? Or I can only uses the cloneset
to backup the file system online.
Wellcome any suggestion.
David Lee.

| 1038.1 | Use ADVFS clonefset... | BRSSWS::DEVOS | Manu Devos DEC/SI Brussels 856-7539 | Thu Apr 10 1997 10:32 | 16 |
Hi David,
While you can use "volassist snapshot" to create a "copy volume", you
will not be able to mount it on any mount point, because ADVFS does not
accept to mount "twice" the "same" filesystem.
So you should better use the ADVFS clonefset for the backup. Moreover,
creating a clonefset is VERY VERY FASTER than LSM snapshot as only the
hierarchy structure is copied.
But, be carrefull if you intend to backup the clonefset by NetWorker as
it regards any file in the ADVFS clone as a "sparse" file and can
transform an oracle flat file in a sparse one !!!
Manu.
