Replication jobs 20 seconds delay

Pierre_J

Hi there,

We have configured AIR for our both NetBackup environments. Every Replication job (also the ones which replicate very small SQL transaction log backups) suffer from a 20 seconds delay between each file.

Each delay occurs between the lines

Replicating images to target storage server
Info bpdm (pid=37580) EXITING with status 0

I think this has nothing to do with the transfertime of the image because it occurs at al smaller jobs.

Do we have a firewall issues causing timeouts or so?

Any help appreciated.

Peter

There is some some overhead involved in setting up a replication. if 20 seconds is too much I cannot say. 

If not already done so, you should consult the "Best practices for using Storage Lifecycle Policies and Auto Image Replication in NetBackup 7.6"

http://www.veritas.com/docs/000018455

it is a very well written document.  Hint: take a look at " Minimum size per duplication job". This may save you a bunch of small replication jobs.

Nicolai, thanks for your reply.

The document is, as far as it is about SLPs, merely a list of SLP Parameters and their effect, for instance when a job will start.

The delay we are seeing is -within- a job.

I cannot find a document about performance, ports or whatever.
