What is the correct way to configure the client to back up =
/vol/common/.snapshot/nightly.0 . =20
1) Do I just enter this path in the file list of the client ?  =20
2) Do I need to change anything else regarding my client configuration =
or Policy type?

I thought that whenever I ran a backup with policy/client type NDMP it =
issued a Dump command on the filer which in turn caused a snapshot to =
take place.=20

But my aim is to first specify a path to the snapshot folder and =
secondly for the Backup not to issue a snapshot command.  Maybe I am =
missing something - like the backup, by default, will not try to take a =
snapshot of a snapshot?!

  I'm imagining that vol0 is not snapmirrored.  :-]



  You have to back up a snapshot rather than the volume itself on a =
snapmirrored volume.  This is due to the fact that a snapmirrored volume =
is read only and cannot therefore have a snapshot created against it.



  You would need to backup something like the following:



  /vol/common/.snapshot/nightly.0



  This will work.

  Hi,  Can anyone backup Active SnapMirrored
  destination volumes on a netapp filer?  =20

  Configuration:
  2 * NetApp F820 Filers with OnTap 6.1.3R2
  W2000 SrvPk3 is Master server
  NBU 4.5 MP2 on Master server

  SnapMirror is in use to snap two volumes from Filer 1to Filer 2

  Filer1
  I can successfully backup all volumes on Filer1...
  /vol/vol0/
  /vol/common/
  /vol/users/

  Filer2:
  Two out of three of the volume backups fail on Filer2.

  The error is NDMP backup failure (99)  - suggesting that the file list =
is not vaild!
  The two volumes which fail are snapmirrored (active).=20
  /vol/vol0/ is successful as is any extension of the file path, i.e =
/vol/vol0/home/ .
  My configured file list is valid and identical to Filer1.


  Thanks for any help received.

  Mark
