Disaster Recovery saveset critical volumes are backing up daily for incr level

Hi there,

Is not at all backed up? hmmm, don't agree with you:

OSSR_D          level=full,    60 GB 01:14:13 155938 files

OSSR_C          level=full,    36 GB 01:53:12 162564 files

First is backing up the drives as such (you see incr) and then the DISASTER RECOVERY.

Do you have any directive set for that client?

If you have any directive to skip something, then remove the directive and check again.

Please check again the output and if needed run the required mminfo queries, as I don't see any problem here.

Thank you,

Carlos

Hi Xao,

I agree. But disaster saveset critical volumes are backing up even with incremental level. This s what the isuue is.

Hi Carlos,

We do not have any directive for this client. it is blank. Moreover, problem here is OSSR_C and OSSR_D are backing up daily. We have daily incremental - full Saturday schedule for this client.

In general, above 2 save sets OSSR_C and OSSR_D should skip for incremental level. But this is not happening.

Please revert for clarifications if any.

You may wish to test it with 7.6.SP5 latest build to verify behavior. I believe this has also changed between NW7 and NW8 so moving further will bring more changes to how it works (I can't say really how it does as I do not use DR savesets and by default I disable them).

Hi Crvelin,

Client is running with 7.6.3.0.Build.840. It is Windows Server 2008 R2 6.1 machine

Thanks for the information. We do have similar WIndows 2008 servers with same build and configuration running with 7.6.3 client version and the backup is running successfully.

When I checked with mminfo command, i could see only OSSR_C & OSSR_D but not DISASTER_RECOVERY:\ save set. Normally it will have size of 15-20 MB max.

Hope this will help in further troubleshooting.

What is the client version you run?

If I understood correctly, you found similar win2k8 box which does work the way you expected.  Compare it from OS side (patch and service pack level) and NSR side (schedule).  Then for both, run backup from client and see if you get the same results.  If not, re-run them in debug mode and see where does it start to be split brain.

Hi Crvelin,

Both servers configuration is same. Also, i have ran the backup with save command from client with debug mode 9. However, did not find any. Really confused where the problem is :-(

The skip of files when DISASTER RECOVERY:\ saveset do full backup may be because you have a local directive if you don't see a global directive defined in your client resource. Look for file name ".nsr" in all of your drives.  Also keep in mind DISASTER RECOVERY saveset is skip in incr backup.

When you compare debug outputs there must be difference as you get different actions for these server.

I did a check against one server where this is allowed and it "acted" as it should; when full schedule is done DISASTER RECOVERY is called and OSSR savesets are done too.  When incremental is done then DISASTER RECOVERY is skipped and as consequence OSSRs are not made.  With that said, I did found a bit strange to see during once instance that OSSR_D was done twice.  Here is example:

So, it looks fine except OSSR_D was taken twice. I checked quickly logs, but there all is fine too:

nsr_render_log -S "yesterday 21:00:00" /nsr/logs/daemon.raw | grep OSSR_D | grep 70896 09/13/13 21:32:31  0 0 2 1 28194 0 nsrd :OSSR_D saving to pool 'dataR' (dataR.005)  71659 09/13/13 21:39:09  0 0 2 1 28194 0 nsrd :OSSR_D done saving to pool 'dataR' (dataR.005) 6140 MB 70896 09/13/13 21:54:58  0 0 2 1 28194 0 nsrd :OSSR_D saving to pool 'dataR' (dataR.003)  71659 09/13/13 21:58:56  0 0 2 1 28194 0 nsrd :OSSR_D done saving to pool 'dataR' (dataR.003) 6140 MB

I suspect this might be good indication that this DR savesets are somewhat strange in how they work However, I also see that client is running older NW client:

echo p | nsradmin -p 390113 -i -  -s | grep "NetWorker version"            NetWorker version: 7.6.2.7.Build.697;

So, I would suggest that you update client to latest 7.6.x (see ftp://ftp.legato.com/pub/NetWorker/Cumulative_Hotfixes/7.6) and see if that makes any difference for affected client.  Due to how it works (or worked), I said to myself that for my env I won't use DR until I don't move to NW8 (as otherwise I get data backed up twice via regular and OSSR savesets) so I didn't pay much attention to this feature in NW7, but obviously earlier code might have had some defects which may explain also a problem you described here.

Hi,

We also facing same issue on one of our client. But it got resolved after upgarde the networker version (upgrade it 7.6.3. or upper )

If you want to check in depeth please run below command on client machin

save -D9 -vvv -s nw_server -b Poolname "save set" > drsave.log  2>&1

check log drsave.log, why that drive took for full bakup
