We never got OST license here but use Deduplication. We do it using 10 GB Ethernet NFS mounts from the Dedupe appliances on each of our master and media servers. It may not be cheaper in the long run to buy a 10 GB switch and 10 GB HBAs for every server (although some now come with embedded) than using OST (especially if you already have a fibre san). Here our solution evolved from 1 GB NFS to the 10 GB with switch so has been done over time. Both the Data Domain and the Quantum DXi dedupe appliances allow for the 10 GB (which runs at fibre speeds but does Ethernet instead of SCSi).
My understanding is that most of the Dedupe appliance makers allow you to do a setup to wherein you have one (or more) unit(s) on site and similar offsite and do background synchronization from the onsite to offsite to avoid having to send tapes. Here we are still doing Dedupe onsite but duplicating to tapes to be sent offsite (again because of evolution - we used to backup directly to tape). -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Martin, Jonathan Sent: Wednesday, October 15, 2014 8:25 PM To: [email protected] Subject: [Veritas-bu] Deduplication with OST All, We are currently running 7.5 on Windows and looking to add deduplication appliances as a backup target. Ideally, we would purchase the DPOO (OST/AIR) license to keep track of the images as they write locally and then replicate to DR, but that may not be a possibility based on budgetary concerns. Without getting into the specifics of which deduplication appliances we are looking at, I can safely assume that we can use a DSU or DSSU to write to a local CIFS target (e.g. \\Prod-Appliance\Backup1 replicated behind the scenes to \\DR-Appliance\Backup1). I am looking at a scenario where we use VM replication to replicate the master/media servers from Prod to DR. When I bring up this master/media in DR, could I use a hostname/DNS alias to make \\Prod-Appliance redirect to \\DR-Appliance? I realize that this is essentially a "poor man's OST/AIR", but this may be the path I have to go down due to budgetary constraints. Is anyone doing anything similar to this? In previous versions of Netbackup I could crack open the catalog files to modify the fragment locations (e.g. E:\Backup --> F:\Backup) but it looks like those pointers have all been moved (into the DB?)
