slow backup process in backup exec 2012.
There is server Dell PE 720xd with array 8X2Tb SAS RAID6. Backup exec installed of this server. Array include big file. When I do simple copying inside array copy speed equally 200 Mb/sec. When I do backup Execbackup copy speed equally 10 Mb/sec (600-700 Mb/min), 10 times smaller than expected. Compressing is off. CPU-utilization - 5%. RAM-utilization - 1.5Gb, 6,5GB free. What is problem?
