Dump-file Input Location
As the input files for crunchy-pgrestore, files generated by crunchy-pgdump are retrieved in a mounted backup volume location, using the database host name plus -backups as a sub-directory, then followed by a unique backup directory based upon a date/timestamp. It is left to the user to restore database dump archives in this current version of the container.
