Khurram, Flashbackup will improve the performance (it caches the data as a sort of snapshot then backs-up the snapshot so it's like a large file rather than loads of small ones, or something like that....) but because it works per volume, you need the space for the cache, which is at least the same size as the volume you are backing-up. It will improve performance for loads of small files but probably won't help too much if they are on a huge volume and they take up a small % of the space. Cheers, Tim

We have a server with a large number of small files (100k to 4MB) and its performing quite poorly on SAN based backup (5MB per stream). Can anyone advise some tuning parameters to improve this speed? The library is L500 with FC LTO3 drives.
