Post script executing 1 minute after backup starts (savepnpc)

Question

We have recently configured new backup of one FS on HP-UX (NW client 7.4.4) with savepnpc and cannot figure out why does post script not work properly. This is not the first time we are using savepnpc in our environment. This particular FS is about 100gb in size. As you can see below, within 1 minute it thinks that the backup is done and starts post command. This backup takes at least 1 hour to finish. I do not see any other errors in daemon or savepnpc. The backup also completes fine. I have even tested different saveset (about 10gb) with just echo commands as pre and post but same thing, it starts post in 1 minute. We have two other cold backups configured from the same system and they are fine. Any idea? EMC is suggesting to upgrade NW client to 7.6 (higher than my NW server) 10/02/10 23:01:13 preclntsave: Starting up the precmds.10/02/10 23:05:22 preclntsave: All command(s) ran successfully.10/02/10 23:06:23 pstclntsave: All savesets on the worklist are done.10/02/10 23:06:23 pstclntsave: Starting up the pstcmds.10/02/10 23:08:02 pstclntsave: All command(s) ran successfully.10/02/10 23:08:02 pstclntsave: Exited. NW client has already been restarted, /nsr/tmp and /nsr/res/nsrladb renamed. NW Client - HP-UX - NW 7.4.4.Build.634 NW Server - HP-UX - NW 7.5.2.Build.492

First thing I would have suggested would be to clear out the client's nsr/tmp which I see you have already done.  Does the backup complete at a time after the completion of the post script as shown in the log output?  What does the log show there?  What are the specified savesets in this instance?

This is a known issue:

ftp://ftp.legato.com/pub/NetWorker/Cumulative_Hotfixes/7.6/Cumulative_7.6_readme.txt

LGTsc33068 (NW00104479): SAVEPNPC: pstcmd runs 60 sec after precmd completes

This fix is not listed in 7.5.x, but EMC might have made a patch for 7.4,x or 7.5.x. In addition, 7.4.x is no longer supported.

Best thing to do is to open a support ticket to inquire about this escalation.

Good luck.

I have upgraded NW client to 7.6.1 as suggested by EMC and it did not fix the problem. To make it simple, we ran savepnpc with echo commands (pre and post), but once again savepnpc logs reported that the backup was completed in 1 minute and executed the post command (it took about 57 minutes to complete the backup). Now EMC wants us to upgrade the NW server, which I am very reluctant to do!

The backup takes about 1 hour to complete, it does not finish in a minute as shown in the savepnpc log.

What does the log show there? What are the specified savesets in this instance?

Daemon logs does not show anything abnormal, just regular savegroup completion notice when the backup is done

We have only one saveset (regular file system) specified

Wallace Lee already mentioned it. PLease look at https://solutions.emc.com/emcsolutionview.asp?id=esg83459 Open a case with EMC support and ask for a port of the fix to 7.6.1

Well, despite not being supported any longer, you may wish to ask for patch.  I have HPUX system which I had to patch to avoid this problem some time ago.  I checked the server and it is running 7.4.5.4 so I guess 7.4.5.4 and later are not affected.  I didn't see also anywhere mentioned this has been an issue with 7.5.x so perhaps it was not, but since updates for 7.4.5.x and 7.5.2.x were released at the same time you should not have an issue with 7.5.2.4 if you have it somewhere.  To learn that this is still an issue with 7.6SP1 is a bit - disappointing.
