Abstract: Disclosed are systems and methods for using a priority cache to store frequently used data items by an application. The priority cache may include multiple cache regions. Each of the cache regions may be associated with a different priority level. When a data item is to be stored in the priority cache, the application may review the context of the data item to determine if the data item may be used again in the near future. Based on that determination, the application may be configured to assign a priority level to the data item. The data item may then be stored in the appropriate cache region according to its assigned priority level.

Abstract: Backup file path determination is described. A request is input from a source device to access a backup file on a storage device. One or more paths to the backup file are output to the source device. A determination whether the backup file is accessible to the source device via a path of the one or more paths is enabled. Access to the backup file is enabled via the path if the backup file is accessible to the source device via the path.

Abstract: Network user access impersonation for multi-threaded backup applications is described. A backup application receives a first user identity and a second user identity of a set of user identities. The backup application calls a network file system service. The network file system service applies the first user identity to a first thread of a set of threads of a backup application. The network file system service applies the second user identity to a second thread of the set of threads of the backup application. The network file system service enables the first thread to access a first backup file on a first network storage device based on the first user identity. The network file system service enables the second thread to access a second backup file on a second storage device based on the second user identity.
