More info about the MT command

How can setmarks be utilized in a backup, can you backup a group of files and create a "setmark" and use that setmark "count" in the restore command.

Basically, if I utilize the "smk" command, does it give me the option to bypass counting individual file marks, and group together multiple files.

Thanks for any help in this regards.

The question regards our current procedure for backing up a Progress Database (Version 9.1c); with the implementation of storage areas, the fsf command will no longer search to the right area of the tape to restore the database.

We run a script that backs up multiple databases, and during the progress restore we run the

mt [device] rew
mt [device] fsf 0
prorest [database] [device]
mt [device] rew
mt [device] fsf 1
prorest [database] [device]

--- every database after the first will not restore.

Prior to the implementation of storage areas this worked, now it doesn't. Does anybody have any ideas?

Should we add an EOF or SMK command to return the record or setmark counts. And if we do, how do we use these in the restores.

Thanks in advance.
