Hello,
Do you have this problem with any particular tape/s or with all of them?
Please check the tape for read/write errors, try the backup and restore with a new tape.
You may also rename the catalog folder, disable option to use media based catalogs and recatalog the tape before retrying the restore.
Was the backup successful? Please check the option to verify that backup to ensure that it can be restored !
