I know that TSM can do both serverfree and lanfree. My impression of these is that for lanfree the client node asks TSM over the network where to place files. The TSM server tells the node and the node talks to the tape drives directly. Since I have four tape drives (that I can put onto the SAN fabric) then only four nodes can backup at once?
With serverfree where the TSM server talks to the ESS/shark directly, how does TSM get things that are inconsistent like database files that have potentially changes in memory? Also, since TSM does not know the end platform, how can TSM backup files? Does it only back up blocks and the client must ask for enough blocks to make up the files it wants to restore? Mike
