Systems and methods for managing a backup process of a database are disclosed. Typically, one or more backup logical unit numbers (LUNs) are identified in a backup management file from one or more available LUNs identified in a universe file are allocated. The backup management file comprises a plurality of data containers, each data container specifying a subset of the one or more backup LUNs capable of backing up a database comprising one or more used database LUNs. One of the plurality of the data containers are allocated for a current backup of the database as indicated in the backup management file. The backup management file is checked and updated as necessary so that the one or more backup LUNs remain available as indicated in the universe file.
