This configuration parameter specifes the kind of data storage to use. For a single-tape configuration, it may just name the tape device:

tapedev "tape:/dev/st0"

but in most cases it will name a changer that can find the volumes Amanda needs to do a backup or restore, e.g.,

tapedev "chg-disk:/media/backs/amanda/DailySet1"
tapedev "my-changer" # refers to a "define changer" section elsewhere
tapedev "chg-multi:s3:mybackups/T{01,02,03,04,05,06,07}

-In most Unixes, including Linux, there are two devices per tape drive, the rewind device and the no-rewind device. The rewind device rewinds after each access, the no-rewind device does not. So to read or write several files in sequence to the tape drive, you must use the no-rewind device, and you must manually rewind as necessary.
