But always the "same slowdown as it goes" seems to occur. While not an ideal runtime, I can live with it if the backup would run faster than tape once the file is created. bkf it takes about 2 hours while the backup idles until the file creation is complete.

To disk, we are getting anywhere from 250 mb/minute to 1,350 mb/minute.half speed at best or much, much worse What seems to happen is that the disk backup will start running at near tape speed. To our super dlt tape drive we are able to backup our 330 gb system at approximately 2,500 mb/minute or about 150 gb an hour. Our tests have been frustrating and disappointing. Since we are moving towards a 24x7 operation, we purchased a new server and storage array with hopes of achieving better transfer rates backing up to disk rather than tape.īackup Exec for Windows 11d with R/3 agent 64-bitġ2- 750gb SATA drives in a raid 6 configuration ![]() We are currently using Backup Exec for Windows 11D to perform an online backup of our 4.6C system to tape.
