Sorry, backing up into a TSM Server with TSM Storage Pools and TSM Tape Library.

What are you backing up to? tape? disk? purpose-built storage like a Data Domain?

We cannot rewrite the requirements, they are set! I have discussed with several colleagues, they suggested a daily incremental, 4 or 5x weekly full, and maybe 12x monthly full Backups copies. In summary 19 copies of data (~500GB) taken, 12 with a retention time of one year, four or five with retention time of one month, the inactive daily incremental copies have a retention time of 30 days. Active copies NEVER expire. 19 copies of about 0.5 TB, which will probably never be used, is a huge overhead, even when we a reducing the monthly backups to two or three copies, there are still many never used copies. In our case, we are going to pay for the storage, since we are using TSM VE and Linux VMs as guests, since we do not see a possibility for charging the different owners of the VMs. Does anyone know a better and less expensive solution for fulfilling this requirement with IBM Spectrum Scale Protect Ciao Andreas -- Andreas Landhäußer +49 151 12133027 (mobile) aland...@gmx.de
