Many years ago, amanda was a once a day design, but about 15 years back it was optionally made aware of time of day. From man amanda.conf, it now says: usetimestamps bool Default: Yes. Deprecated, the value is always Yes. This option allows Amanda to track multiple runs per calendar day. Its # commented out in my config, has been for decades. There is one option that can make amrestore in the event of restoring to a new drive in case the old one failed, as if its set, it checks the device and will not restore to a different replaement drive. I disabled that check years ago because drives do fail. See your amanda.conf under define application-tool app_amgtar { where there are a number of properties defined: property "CHECK-DEVICE" "no" #use '--no-check-device' if set to "no" This one can bite you if set to yes.
