Adding a new network circuit for Netbackup replications

[Thomas_Anthony]

Hello, 

We use SLP policies to replicate NetBackup backup images, stored on EMC Data Domains, from one site to another on a daily basis without problem.  Now ATT is installing a new network circuit between the sites. Mgmt wanted to get any recommendations, or potential configuration changes needed for a new circuit.

Thanks !

Environment: both sites have NetBackup 7.7.3 on Linux Master/Media servers writing to EMC Data Domain disk units

NetBackup uses optimized duplication to perform replication between DD. What that means is NetBackup update it's catalog information and just send replication commands to DD . Actual replication logic and bandwidth consumption is decided by DD. So if there is change in wan link or any networking component you need to check with EMC DD support. 

No configuration change is required in NetBackup unless you are adding any new replication source/target.
