Hello, If you were to eliminate hardware bottlenecks, i wonder if using compression directive might improve backup performance ? Are you using AFTD atall, if not perhaps a VTL or AFTD may also be wor

You should be able to get more performance out of the drive - 50MB/sec suggests your drive is not running at the fastest spindle speed given that you are sending uncompressed data to it - maybe the
