Backup Exec 20 Speeds
We back up a lot of data to tape and some of the jobs are over 6TB in size and are taking over a week to complete so I'm trying to improve speeds.
Slowest link in the LAN operates at a gigabit so I would expect to see speeds around the 200-250Mb/s mark which I am when copying files using something simple like Windows Explorer.
Backing up to tape using a test file set of a single 5GB file and twenty 200MB files, gives me speeds of around 120-160Mb/s while using hardware compression but this is not even in the same league as the stated speeds.
I've been experimenting with settings in BE to try and improve speed and have made some marginal gains tweaking the block and buffer sizes along with the number of buffers and the high-water mark.
Does anyone have experience with making significant improvements to their tape backup speeds?
