We have about 700 TB backup data. Aside from issues with TOCs, copy pools and some others (which I am confident TSM development is working to remedy !), we're pretty happy with the service. Since most NAS volumes are quite large, some multi-terabyte, we have been co-locating by filespace. I wonder if anyone out there is co-locating their NDMP backups by node ? The reason I want to do this is to break up some filer volumes into (many, like 100's) virtualfsmapping(s). This would require a tape for every virtualfsmapping, and I would like to minimize the number of tapes per node, but do not want to scatter differentials over too many tapes, which I suspect will be the case, if I co-locate by node. We're using STK 9940B drives, and getting around 300GB per cartridge. Thanks for any comments. Regards, John Bremer
