There is no reclamation on a diskpool. Over time the deletion of (very) small data blocks will make it heavily fragmented which will definitely impact you performance... Kind regards, Eric van Loon AF/KLM Storage Engineering

A diskpool should be used for things such as disk between the backup client and tape for temporary random I/O storage that can handle an unlimited amount of sessions. A fileclass storagepool is better suited for long term storage. I create a diskpool for VE metadata when using dedup on the filepool and use fileclass storagepools for permanent storage on disk with or without deduplication. Are you planning on using deduplication on disk? On Fri, Aug 21, 2015 at 10:12 PM, David Ehresman < [email protected]> wrote: > Gary, > > TSMVE 7.1.2 makes file level restores a reality.
