Hi Corinna,
Setting tar's -b size up resulted in a radical increase. Still not
streaming but real close and workable. Reading in a 100GB tape with
500MB to 1,500MB files should take about three or four hours instead of
three weeks! I'm going to keep experimenting to see if I can get it to
stream which should bring it down to 2 hours. Thank you!
In experimenting I found '-b 20480' was "too large" and did not work. I
have not had a chance to determine at what size tar breaks.
Any idea why I can't set the block size greater than 32K using
"mt setblk"? We have a number of tapes which have a 64K block size and
I'd rather having to rewrite them.
Thank you again,
Bill
