I have a few questions in order to verify what I understand.
Is there some deduplication built into NB 6.5.2/6.5.3 Win XP client?
No. NetBackup's only dedupe is via PureDisk.
If I have to purchase PureDisk 6.5, I have further questions. We haven't installed PureDisk on XP, we do have it installed on a bunch of Windows 2003 servers (I'm not the PD expert in my group - somebody else is doing most of the PD work). We are not yet using it as NetBackup storage unit - that can't happen until we install NBU 6.5.2. Today, the data gets sent to a dedicated PureDisk appliance which is SuSe-based.
1) If a client has two files with the same data, do both files get sent
to the Netbackup Server?
Nope - the client sends enough information over to be able to determine whether or not any data needs to be sent.
2) If I have two clients with the same files, do both files get sent to
the Netbackup Server?
Nope. In fact, we've "seeded" our PureDisk server with copies of the data to speed up the initial backup of the remote sites - this is especially useful if the remote site has a slow network link. Dump the data to a USB drive at the remote site, ship it to where the PureDisk server is, and back it up first.
3) Do I need to update the Netbackup Client to support PureDisk?
You don't actually have to install the NetBackup client at all. The PureDisk interface to restore files is actually pretty good.
