CONTROLLING RESOURCE ALLOCATION FOR BACKUP OPERATIONS

摘要

Various embodiments of a computer system and methods are disclosed. In one embodiment, a computer system includes a backup application coupled to interconnected storage resources. The backup application creates a database of storage resources, wherein each database entry corresponds to one or more storage resources and is associated with one or more user-defined attributes describing the suitability of the associated resources for a backup operation. The backup application creates and stores a configuration of storage resources for a backup operation. Each storage resource is selected based on a value of an associated attribute. The storage resources may include logical unit numbers (LUNs), mount points providing access to LUNs, and hosts having physical access or network access through other hosts to mount points. An attribute specifies that the associated storage resources are either required or preferred for a backup operation. The database and configuration are created at backup application run time.
