arq_restore can view and restore from both AWS and local backup sets. If you've got a backup set at another destination type, copy the backup set's data to a local folder and then add that as a target to restore from.
To configure an AWS target you'll need an access key ID and secret access key to access the AWS data. See the Arq help for more information on creating those keys: Create AWS Key Pair
To list "computers" (a.k.a. "backup sets"), use the 'listcomputers' command with the nickname for the target you've configured.
$ arq_restore addtarget mydisk local /Volumes/8tb/backups
$ arq_restore listcomputers mydisk
target: mydisk

To list the folders in a computer's backup set, use the listfolders command:
$ arq_restore listfolders mydisk 725FAF56-B678-4258-BE24-E64E400D750F
enter encryption password: ...
target mydisk

folder /Users/stefan/1somefiles
uuid 8029F33B-A936-491D-B62D-123997161062
To restore (download) the latest backup of a folder, use the restore command:
$ arq_restore restore mydisk 725FAF56-B678-4258-BE24-E64E400D750F 8029F33B-A936-491D-B62D-123997161062
