Netbackup AIR - restricting REPLICATION jobs

I have a situuation whereby the link between two NBU sites / domains has been inactive for some time, and the link has now been upgraded and is available again.

I suspended secondary operations on the SLP's in the primary site during this period, and as a result now have a couple of thousand images awaiting replication to the secondary site.

Before I re-enable the secondary operations on the SLP's I want to ensure that I don't have hundreds of replicaton jobs starting at once, as I have seen this in the past and the system becomes unresponsive.

How can I limit the amount of replication jobs that will be submitted as I want to limit this to a manageable number (say 20 concurrent).  I know I can limit the amount of streams on the Storage Server / Disk Pool, but I am afraid that the replications will all kick in and the backups will not have any available streams to work with.

Bottom line - I want to continue to allow my backups to run but also have a limited number of replication jobs running concurrently allongside them.

Any input appreciated.

    Hello,

    Did u ever find a way to achieve this?
    i'd love to know if there was a way to let backups continue but limit the replication operations somehow.

      onepranav limit in what way(s) ?   max source concurrent replication jobs ?  max target concurrent replication jobs ?  run/scheduling windows ?  max network bandwidth ?  max quantity/volume of data GB/TB ?

        Going back to my original query -

        Setup -
        SLP tied to a storage unit -> that storage unit is against a disk pool -> Disk pool is setup for MFR based datadomain to datadomain replications.

        The amount of backups/replications that can be run are controlled via the stream that we limit of the disk pools or the SLP parameters. When we change the stream count, it affects both backups and replication jobs. Say i have 100 streams setup for my Disk pool. My question is if there is a way to limit the replication jobs to use only 20 of the streams and let backups use 80 streams.
