Hello I was wondering if anybody could help or advise with the following question.
I need to devise a solution to speed up DR for one of my customers. Currently their DR solution is the classic restore from TSM DB tape and then load all of the off site tapes into the DR library and then perform the client restores. The problem is that the TSM DB restore can take in the region of 5 hours. The TSM DB is 45GB. I was thinking of using the following method. Can any one see any issues with this? *On the primary TSM server:* They have a Windows 2003 Standard Edition TSM server. I am proposing that we set up TSM DB and log mirroring, one copy on local disk and the second copy on SAN attached disk. *On the DR site:* They also have a TSM 2003 Standard Edition TSM server. When DR is to be tested / invoked, I would propose that they re-zone the DR TSM server to access the LUN that contains the DB and logs. Ensure that the DR TSM server's dsmserv.dsk points to the mapped drives. Note the the TSM tape library is also SAN attached. Any comments / experiences would be appreciated.
