I got a 300GB file system to backup. I split it to four streams, and
multiplexing them to a single IBM LTO-2 tape drive.
1st stream is 53GB finished in 2 hrs.
2nd stream is 53GB finished in 2hrs.
3rd stream is 80GB finished in 3hrs.
4th stream is 120GB finished in 4hrs.
However, when I did a full restore, it only took 2 hours.
Does anybody have experience restore faster than backup?
