Optimised Duplication Between MSDP and VTL
NBU 7.5.0.7
Hi all,
Just wondering about an SLP configuration... Backup runs to an MSDP then duplicated to and OST VTL.
Because the VTL is OST enabled, will it be an optimised duplication? ...
- 10 years agoThere is no such thing as OST enabled VTL. Vendor-supplied OST plugin installed on NBU media server is for disk pools only. VTL may be on dedupe storage, but is presented to OS and NBU as normal tape. Duplication to VTL will be rehydrated.

Optimized duplication mostly only happen on two devices of same type :
e.g.
MSDP- > MSDP
Data Domain > Data Domain
Cross type duplication will be non-optimized (full size replication):
e.g
VTL -> MSDP
Data Doman -> MSDP
