All,

Our customer has a set of aging DD890's which we intend to replace with a set of DD9300 systems.

Current situation:

NetBackup 8.0, DDboost 3.3, DDos on D890 + DD9300 = 6.0.1.10

MFR is used to duplicate backup jobs.

All necessary licenses.

Our intention is to setup Collection replication between a DD890 and a DD9300 to create an image copy of the data.

Once the initial sync is complete, we shutdown the NetBackup Media Server(s), do a final sync and break the replication.

Next step is to update the DNS (Forward and Reverse records), so the DNS entry points to the (Data) IP address of the DD9300.

By doing this, we do not need to do any form of re-configuration in NetBackup.

Questions:

Will NetBackup detect that there is now another DD unit?

     The Storage Server in NBU is based on the DNS name and credentials

     We only changed the IP address for the DNS record and credentials are identical in the old and new DD

     (possibly also copies as part of the collection replication).

Will NetBackup continue to work with the (replicated) data on the new DD?

     One thing we try to avoid is a re-catalog of the data

An alternative proposal is to make the DD9300's available in NetBackup.

Next step is to write the backups with a retention < 60 days to the DD9300 and after the 60 days, use NBU duplication jobs to copy the remainder of the data (contained in an Mtree with Governance Retention set to infinit)

Problem here is that this whole process will take 2-3 months whilst the maintenance contracts on the DD890 will expire in a few weeks, so wee seek a faster method.
