I have a new new Seagate Tapestor drive and would like to know how I can
use it better.
I have created a backup and restore script. They are attached to this
email.
Those scripts work fine, but I am not sure how to determine how much of
the tape was used during the last write. Since I am using "dd" to write
to the tape device it will tell how much was written, but I am wondering
if there is more I can do.
Are there any good doc sites out there for using tape drives? I have read
over the FreeBSD docs and do not see anything about getting the info I
want.
