Monitoring AIR Replication of a large backup image

[cimo]

Hello guys!

I have to 5220 Appliance with 2.0.3 firmware.

I have a large backup image (1.8tb) that are replicating to my DR Site from 06/07/2014 11:56PM. The duplication job is still running, I looked in bpdm debug log for errors but I don't find anything.

How can I monitor my replication?

How much time do it needs to complete?

How much data have been replicated?

Thank you!

Simone

I would look inside  /disk/log/spad/replication.log    & the output of

/usr/openv/netbackup/bin/admincmd/nbstlutil report -lifecycle <AIRname>

Thank you watsons,

This is the backup image being replicating:

med5220im01:/disk/log/spad # nbstlutil stlilist -backupid msiefsp_1402088404 -U

  Copy to *Remote*Master* of type DUPLICATE_TO_REMOTE_MASTER is IN_PROCESS

It's about 1.8 tb

here is the output of the report command you suggest:

med5220im01:/disk/log/spad # nbstlutil report -client msiefsp

Backlog of incomplete SLP Copies

Total:                                                         1     3840509 MB

why is there so much data to trasfer? how much data have been replicated?

[watsons]

Your SLP DR_SLP_MED5220IM01-REPL_Ret-14days  may have a total of 3840509 MB data to be replicated to remote master, the image msiefsp_1402088404 (1.8TB) is probably just part of the 3.8 TB. Why is there so much data? Really depend on how you configure the backup to go through AIR. If you don't want that much data, just scale down your backup selection.

In /disk/log/spad/replication.log, you can do a "tail -f" to follow the progress of the replication, see how fast it goes. Some performance tuning is available in

Thank you again watson, but I need some hint to understand the replication.log

how I find the exact lines related to my big replication? I don't find the backup image name, and the "Job ID" that I read doesn't match with what I see in bpdbjobs command:

June 12 09:02:42 INFO [1092761920]: ===  Replication Monitor  ===
June 12 09:02:42 INFO [1092761920]: Job ID: 1624, Target: pdde://med5220ps01, Segments Processed: 5355956, Age: 152025 seconds
June 12 09:02:42 INFO [1092761920]: Job ID: 2170, Target: pdde://med5220ps01, Segments Processed: 2096539, Age: 10398.1 seconds
June 12 09:02:42 INFO [1092761920]: There are 2 replication jobs currently running and 0 jobs waiting in the queue

The first job (ID 1624) is running since 42 hours, so it could be my job... so I know that 5355956 segments were processed... but what is the total number of segments?

Thank you!

[watsons]

The segment is for deduplication processing,  I don't think you can work out the actual duplication progress by this. I will try to find out if there is other way..

[watsons · Accepted solution]

After some research, I found that the "segments processed" you highlighted was the only way (that I know of) to trace the progress. It's possible your issue is related to this: http://www.symantec.com/docs/TECH181784

If you need to determine the # of POs, log a case with Support to find out or upgrade first to see if it can help.

hi, cimo

It's recommended to use Opscenter to monitor your SLP and AIR.

In the following guide, you'll see how to report on SLP and AIR with Opscenter. I think this will resolve your problem.

Just a snapscreen for reporting on AIR.

Thanks
