Hi,
Dumb question: is there a good reason to NOT migrate data from a disk storage pool to a tape storage pool? I base my view on the idea that, if you can, why not migrate your data to a safe place like tapes?
Technical things to consider:
1) There are plenty of filling and scratch volumes available, but the acquisition process is slow and is not a simple contracting process;
2) Drives/library idle (most of the time);
3) Backup server idle (most of the time);
4) No restore process in progress;
5) No need to restore data in the next hours and, most likely, in the next days;
6) Volumes from the disk storage pool that use DISK device class are stored on a storage subsystem disk with RAID 5 enabled (with spare available // no storage mirroring // old storage);
7) Backups consists of ...
7.1) unstructured file data and structured data;
7.2) vital data and non-vital data;
7.3) volatile data and non-volatile data;
7.5) TiB of data per week;
8) daily change rate (%) unknown;
9) annual growth rate (%) unknown;
10) TSM administrators are inexperienced with little knowledge;
Thanks in advance,
Zegg
