Hello Sami,

You don't need to configure the sync options. Collection replication will directly copy the file system changes to destination Data Domain in real time.

Hello Leo,

Thanks alot for your immediate reply

You're welcome~

Hi Leo

Currently and after collection replication; all the virtual tapes in DR Data Domain are replicated under vault but in Main Data domain those tapes are under tapes not vault, and all the tape state in DR DD in RO/RD and of-course the tape state in main DD are in RW; so whats is RD state and how can we change the state of tapes in DR to RW in disaster scenario? and keep in mind that main data domain is configured as storage library on main Networker environment and the DR DD configured on DR Networker environment and once we failover Networker we will need to change the state of DR data domain tapes to RW

Your feedback will be much appreciated

As I have it you will need to break the collection replication between Main and DR DDRs. This will change the state of the tapes to RW.

When testing is done on DR DDR perform a replication resync to bring both DDRs back in sync.

You should also be able to use fastcopy to create a "test" copy of the data.
