[Veritas-bu] Device Strategy
Folks, Could I ask the group for opinions on my device configuration strategy? We have built a new 6.5.2 backup domain with a Solaris 10 Master (clustered over two nodes using VCS) plus 4 x Solaris 10 Media Servers and 2 x Windows Server 2003 Media Servers. We also have 2 x Scalar i2000 tape libraries and 2 x EMC disk libraries. Our intention is to share the 6 x LTO-4 drives from each tape library across the Master and all Media Servers. With the disk libraries we have configured 2 x VTL on each disk library with 32 drives that is 4 x 32 = 128 drives. The drives from each VTL have been distributed equally amongst the four Solaris Media Servers only such that each has 8 x drives from each of the four VTLs. The reason for putting the robotic control on the cluster was to keep it highly available such that if we lost a Media Server then we would not have to reconfigure the robotic control onto another Media Server. However, we have discovered that we can't seem to get the wizard to configure the VTLs and their drives correctly. At the moment, unless the robotic control is on a Media Server that has drives from that VTL associated all drives are configured with limitations such as unable to determine robot type, robot drive number is unknown, etc. Even on the Media Server with the robotic control the wizard will correctly configure only the drives directly presented to that host, the other Media Servers get drives configured with limitations too. On the face of it to get this working correctly we would have to assign a VTL and all associated drives to each Media Server exclusively, but we really need to be able to distribute the drives. We are going to try a manual configuration today and bypass the wizard. Has anybody got hosts with robotic control only for a library? Should this work? But then again as I said above, even with robotic control for a VTL on a Media Server with drives, there are still configuration issues for the other Media Servers that share that VTL but with dedicated drives.

[Veritas-bu] Win XP client Deduplication
I have 75 windows client that I would like to backup over the wan. I can't use DLO since we don't have a Windows Domain. I would like to do client deduplication. 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? If I have to purchase PureDisk 6.5, I have further questions. 1) If a client has two files with the same data, do both files get sent to the Netbackup Server? 2) If I have two clients with the same files, do both files get sent to the Netbackup Server? 3) Do I need to update the Netbackup Client to support PureDisk?

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. .../Ed -- Ed Wilts, Mounds View, MN, USA RHCE, BCFP, BCSD, SCSP, SCSE mailto:[EMAIL PROTECTED] If I've helped you, please make a donation to my favorite charity at http://firstgiving.com/edwilts ___ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu

Is there some deduplication built into NB 6.5.2/6.5.3 Win XP client? [DKC] No, there is no deduplication in the basic client If I have to purchase PureDisk 6.5, I have further questions. 1) If a client has two files with the same data, do both files get sent to the Netbackup Server? [DKC] If both files are identical the all the fingerprints will be identical. If the fingerprint exists anywhere within the PureDisk Global Environment, the data associated with that fingerprint will not be backed up. Fingerprints are 128K in size. So the first file will get backed up and the second file will simply have meta data indicating the fingerprints that are already in the storage pool that contain that file's data. 2) If I have two clients with the same files, do both files get sent to the Netbackup Server? [DKC] No. The first one that gets backed up will send the data associated with it's fingerprints to PureDisk. The next server will see that fingerprints already exist for its files and will not be backed up and the metabase will associate that client's files with the appropriate fingerprints. 3) Do I need to update the Netbackup Client to support PureDisk? [DKC] The NetBackup 6.5 Client includes the PureDisk 6.5 Client.
