Dump Location

Backups are stored 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 perform database backup archives in this current version of the container. This backup location is referenced when performing a database restore.
