deduplication
Hi ALL,
we are working on using deduplication technology in our environment but want to have below things clear:Just the basic idea?
- Before NBU 7.x,How do we do deduplication? we use symantec netbackup pure disk?
- Symantec NetBackup PureDisk is a product that provides a complete backup and deduplication environment. It can be used as a stand-alone (PureDisk writes data to the storage pools) or as a back-end for NetBackup. How it is use as standalone and as backend?
- now in 7.1 we have MSDP.This is also using Pure disk?
- What is this MSDP?And this PDDO?
Since PureDisk and NetBackup are seperate products, they have separate version numbers.
NetBackup 6.x can use PureDisk for deduplication. This requires seperate servers for the NetBackup media server as well as the PureDisk servers.
NetBackup 7.x can still use PureDisk for deduplication, using the same number of servers as the NetBackup 6.x example. There is little difference bewteen the two, as the major differences in how the deudpilcation is performed would be on the version of PureDisk chosen. The rest of the differences would be only on the NetBackup side.
NetBackup 7.x can also use MSDP, which is a part of the NetBackup media server (no separate PureDisk product used), which only needs one server: the media server where MSDP will be configured.
