Re: A query about NDMP support
Since I've received no response from the list, I decided to spend a day reading through both the TSM documentation on NDMP and the documentation on NDMP itself. I had thought that NDMP was just a backup protocol that TSM could support. It is not. It is a complete backup system itself. It requires that the drives be attached (dedicated) to it and that it write the tapes itself. This means that you need to share the library and drives (more licenses!) It also needs to manage it's own database of backup data. TSM would only provide a tape storagepool that it would be unable to make a copy of for disaster recovery. TSM would not be able to do tape reclamation on that storage pool either. Basically, it means that NDMP is another backup system to manage, one that does not have the features of TSM that make it most useful to us. As for the 3-way option that Mirapoint would like TSM to implement, it would eliminate the need for the tape drives to be directly connected to the Mirapoint box, It would instead push this off onto yet another box that would be connected to the library and tape drives. Oh, joy! another box to pay for and manage! Of course, I'm sure that they think that the TSM box would be able to house the second NDMP host, possible, but I wouldn't want to manage it. As for adding complete NDMP host capabilities to TSM, well, I expect that eventually that will happen, but not for quite a while. I would not want to use it unless TSM was then able to manage the storagepool like it does it's own. In other words, not unless disaster recovery and tape reclamation were automatically part of the process. In short, we are going to continue using a two stage process for backing up our Mirapoint boxes. We will use the Mirapoint backups to create backup files on another server and then use TSM to backup those files. If I'm wrong about any of this, I'm sure that someone will let me know. *8^) David Jelinek -Original Message- From: Jelinek, David G.

We need 3-way NDMP support in TSM. So is 3-way NDMP a good thing to push for? Do their reason(s) make any sense, and are they valid? Or do they not understand TSM and NDMP?

Re: A query about NDMP support
I am assuming that these disk vols are nfs mounted over some of the hosts systems in your environment . I use to backup these disks vols locally from the server where it is mounted .There is a option to backup nfs mounted fliesystems . Yes - $4500 per NDMP license . Thanks regards . Shekhar Dhotre.
