Use cases where you would need to replicate more than once a day are rare. Most systems are configured to run replication once the majority of backups have completed for the day.

Can you explain why you would like to have two replications per day?

Hi Ian,

maybe there rare, but they exist. Our customer want's to use replication more than once a day.

I would like to configure it, because honestly I do not have arguments why not.

Thank you.

Ideally you'd want replication to run almost immediately after a backup finishes to lower your RPO (assuming you have enough streams available).

I can see the need - as I also have a need to do so.

if my backups finish say at 4 am and I have replication start - but it has to quit when the blackout window hits at say 6am then my replication did not finish - so I would want replication to start up again say at 4 pm (after black out and most of maint window is done) so it can finish replication of last nights backups.

the other option is to have more than one stream of replication.

but it does come down to why - if you run backups, - the run replication and it gets caught up why would you need to run another one before you do any more backups - as there would be nothing new to replicate.

One could probably just have the repl cron task run multiple times a day.

There is a white paper on this site called EMC Avamar Replication Methods and Optimization Strategies that details how to do custom replication jobs..

Generally speaking, properly tuned replication will complete well before the blackout window. Multiple replications are the "nuclear option" so it's best to ensure that replication is tuned appropriately before expending the effort on  creating and maintaining multiple replication configurations.

Replication management is being overhauled in the next release to make it easier to manage multiple replication streams, etc..
