Tapedev

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}
