That depends on how quickly you want to wear the tape system out since
doing it everytime doubles the passes on both the tpae and the drive.

This is also something that I've observed, but I now have in place a
script that converts each tape as it comes around in the rotation to
no compression and variable blocksize, eg 0.
So I'm running amverify on last nights tape just for grins. And
there's no errors being reported in the shell window after about 5
minutes of reading. This is a pleasant change.
I'm curious if it will squawk about the 2 extra, non-amanda files on
the end of the tape. I've made my tapetype a hundred megs smaller,
and I'm adding 2 tar files, one of the indices generated while
makeing this tape, and one of the configs dir in effect at the time
*this* tape was made. I guess I'm paranoid.
Another effect I'm detecting, right at the edge of being un-noticable,
seems to indicate that switching from a 512 byte block size to
variable, seems to have sped it up slightly, (runtimes used to be
about 3.5 hours now seem to be around 3 flat) and maybe even made the
tape hold a few more megs, but this is subjective, I'm creeping back
up on the tapetype size by 25 megs a day till I hit an EOT again.

20 minutes reading now, no errors. I take it thats a Good Thing(tm).
