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.

The disclosure relates to optimizing a mount process at a data storage device. The storage device communicates with a host using a mount process and mounts a master table, the master table caching translation table pointers associated with a boot partition. The storage device then sends a ready signal to the host indicating that the storage device is ready to receive a boot partition read command from the host. The storage device suspends the mount process for a window of time to receive the boot partition read command and executes the boot partition read command if the boot partition read command is received during the window of time. Accordingly, by caching boot partition pointers in the master table, the mount time of the boot partition is shortened to allow the storage device to send the ready signal earlier and provide the host with earlier access to the boot partition.
