Dear list,
We want to implent a new server with large disk capacity to be used for backups. (because our library's are getting too small) We already have one tsm server on aix with 2 library's attached. We were thinking of the following scenario.
keep the existing tsm server on the aix box. Leave the scsi attached libraries in place. Let all sap backups go directly to the tsm server on this box. Reason: the productive sap server is attached with a direct fiber link (separate adapters) and uses jumboframes, on the tsm-box itself we also have sap instances running. This machine has support contracts and a rs6000 (h70) can be considered reliable. (which is what you need when doing sap backups and restores). So for those reasons want the sap backups and logs go to this machine.
On the new server (intel xeon with 6 TB sata) we install another tsm server. We use this server for normal file backups. (file servers, mail servers etc) We create large disk storage pools on the local disks to keep all the data. Once a day i want to make a copy of those storage pools to the library's on the aix-box using server virtual volumes. Since both servers are in the same room and the library is too small too hold all the data i need to check those tape out every day and take them offsite. If this box breaks we can always get a spare box and restore data from the copystoragepools. We think it is ok that we can not do backups for the time the box is broken.
First, is this a reasonable way of doing things. Any things i have missed. Second, the space reclamation of the server virtual volumes kind of bother me. I can see how to reclaim the volumes on the intelserver, that would just work as normal offsite copy volumes but if there is a little bit of data left on a tape because a virtual volume spans from one tape to another there is no way to reclaim this. I could of course write a script that would tell the operator (which is me) to bring the volume back onsite so it can be reclaimed but was wondering if there are better ways of doing this.
Thanks for your help
