Hello, I haven't checked with Netapp yet, but would anyone here know if it is possible to have a ndmp backup going to two tape drives , thus creating a duplicate copy ?
I have a dual port HBA for the tape drive(s) on a FAS3040 head with DOT 7.2.2. The drives are IBM LTO3s and the backup software is NetBackup version 6.0MP4.
I would like to add a second tape drive on the the HBA and do the in-line tape copy rather then duplicating the data at a later time.
Thanks, George Kahler York University
Hi George.
Unfortuneatly, Inline Tape Copy is not an available option using NDMP. (at least in NBU 5.x...as far as I know, there's been no change on that for 6.x)

Not in 6.0 either, I'm not sure if it isnt for 6.5. They changed a lot of stuff in the way a NDMP STU works in NetBackup 6.5, since drive sharing (SSO) now also is supported for NDMP.

In actual fact, SSO for NDMP is supported in 6.0 as well.
6.5 still doesn't support multiple copies from the schedule, and it doesn't work with the new storage lifecycles either which replicate some of the functionality of InLine copy. It'll let you configure the policy to go to a storage lifecycle but it will then error when you try and backup NDMP to it.
The only way around to get something like this would be to take two backups of the same data at the same time from either the same or different policies, but obviously this would double the backup load on the filer. InLine copy does a single read and multiple writes which this method would not do.
Cheers

Hello toasters!!
Check this out.
I have a 6030 running 7.23 Clustered running mostly ISCSI and some CIFS for exchange, etc Running Vista (ok, I'm starting to hate it, and you will know why) IE 7.0.6000.16609 256bit
When I am in filer view, click on snapshots, snapshots reclaimable, my filer goes to 99% CPU, then I get this wonderful error:
HTTP/1.1 500 7854796800 content-type: text/html Oops! Had a problem with that Servlet 500 7854796800 java.lang.NumberFormatException: 7854796800 at java.lang.Integer.parseInt(Integer.java:426) at java.lang.Integer.parseInt(Integer.java:463) at netapp.fv.volumes.snapshots.manage.SnapShotReclaimable.addSnapShotRows(S napShotReclaimable.java:121) at netapp.fv.volumes.snapshots.manage.SnapShotReclaimable.addSnapShotList(S napShotReclaimable.java:151) at netapp.fv.volumes.snapshots.manage.SnapShotInfo.getBody(SnapShotInfo.jav a:449) at netapp.fv.servlets.FilerViewServlet.service(FilerViewServlet.java:555) at javax.servlet.http.HttpServlet.service(HttpServlet.java:588) at netapp.servlet.NetappRunner.execute(NetappRunner.java:422) at netapp.servlet.NetappRunner.run(NetappRunner.java:254) at java.lang.Thread.run(Thread.java:484)
And I have to tell you, the Oops! Is in 28 font; its HUGH, and I get a sarcastic chuckle out of it, then my filer goes back to 5% or so.
I did find something on the NOW site, but its not really that close. https://now.netapp.com/Knowledgebase/solutionarea.asp?id=3.0.3756131.266 5252
Is it just me? Ok, NO I am NOT going to install Linux, its not a option, so don't go there!!
Thanks to everyone, I appreciate the great info and suggestions.
George,
You may be able to do this with IBM's Tivoli Storage Manager (TSM) as it supports "simultaneous write" to multiple backup media (up to 10 copies).
TSM does support NDMP backup, but I don't know if it supports simultaneous write from an NDMP source - but I don't see why it wouldn't...
In this arrangement the tape drives would need to be connected to the TSM server - not the Filer - and the NDMP data would traverse the LAN before being written to disk and/or multiple tapes.
Of course, this means changing your backup software. But TSM is good. :)

TSM 5.5+ allows you to make back up copy pools of NDMP data but I do not believe you can do simultaneous writes to the primary and copy storage pools. The TSM server does not actually handle the writes to tape you define a data mover from the filer to the tape device.

Toasters,
I thought this might work since TSM v5.5 provides a new "Filer-to-Server" mode, where the tape drives are connected to the TSM server. This stores the NDMP backup data in normal TSM storage pools - which should inherit all normal storage pool functions, such as simultaneous write...
However, it seems that simultaneous write is NOT supported for NDMP data - even in the new Filer-to-Server configuration. :( Refer to "10.3 Filer-to-server backup" on Page 146 and 152 of the new TSM v5.4 and v5.4 technical guide: http://www.redbooks.ibm.com/redpieces/abstracts/SG247447.html
And here's a good PPT explanation of the various modes (at v5.4 level) here: http://www-1.ibm.com/support/docview.wss?uid=swg27010813&aid=1
That said though, it does support NDMP backup to a TSM disk storage pool, and from there you could write the primary and copy storage pool tapes (though not simultaneously). At least this keeps the backup duplication workload off the Filer.

Hello,
we scheduled 2 backup task at the same time - original backup and the copy. so all date for the copy is already in the cache and you get 2 tapes in the same time you need for one backup
