A docker container utility to schedule archiving container volumes.

Volumes mounted to a directory under /data will be archived to the volume mounted at /archive inside the Salvage container. Directories are added to a tarball based on the archive strategy and are then compressed with the selected archive compression type. Each archive is timestamped based on when the archive process started running, meaning all archives created during the same job run will have the same timestamp ni their filename. Timestamps are created in the format [year]-[month]-[day]_[hour]-[minute]-[second].
