James,

These are not NDMP, and some are through a firewall, some are not. The reason that it is so is that some are backing up over a VLAN from a datacenter ~1 mile away. However, the biggest issues have been with the server that is adjacent to the backup server.

To expand on the NSR_KEEPALIVE_WAIT, this did appear to have an effect when I invoke savegrp manually (I see the "group running on client" messages in nwadmin), but not when run automatically. It was invoked because of the large files problem that predated me and predated the firewall hardware. It probably even predated the datacenter move that separated our backup hardware from some of our systems.

David,

Thanks for the tip - I had bumped the inactivity timeout to 90, but I'll crank it all the way out. The savesets are listed as aborted, and often have significantly divergent sizes (>5 GB) among the retries, even though the server mountpoint is static throughout the day.

Check the "inactivity timeout" field in the group definitions.
For our large servers, we put this to 1000, and that seems to work for
us.
Also, check your indexes to make sure that it isn't really completing.
Sometimes you can get that message, but you will find that the backup
successfully finished, and is stored in the index.

Subject: [Networker] Networker 7.2.2 clients with large files problem

Sent by:     EMC NetWorker discussion <NETWORKER AT LISTSERV.TEMPLE DOT EDU>


------------------------------------------------------------------------



Hello,

I am running into a problem with scheduled backups on a Networker 7.2.2
server. By setting NSR_KEEPALIVE_WAIT=300 on the clients, I am able to
run full backups of the systems in question but the backup fails when
the scheduled backup runs. The common thread for these systems is the
existence of large files (> 1GB), and they are failing their scheduled
backups the same way as they used to before the keepalive was added:

--- Unsuccessful Save Sets ---

* ie-1:/yesterday 1 retry attempted


I'll run a verbose save tonight to get more details, but I'm curious
what other next steps might be recommended given that it is only a
problem for scheduled backups.

And yes, I know I need to upgrade - working on that as well. Thanks.

Greg
