摘要： Techniques for improving performance of a backup system are disclosed. In one particular exemplary embodiment, the techniques may be realized as a method for improving performance of a backup system. The method may comprise performing a backup of a client device, tracking, using at least one computer processor, references to data segments that are located outside of a unit of storage associated with the backup, calculating utilization of the unit of storage associated with the backup based on the tracked references, determining if the calculated utilization meets a specified parameter, and determining one or more responsive actions in the event the calculated utilization meets the specified parameter.

摘要： A computer-implemented method for taking snapshots in a deduplicated virtual file system may include (1) maintaining a deduplicated virtual file system that stores, at an original location within a non-virtual file system, at least one configuration file storing metadata for a target file and an extent map for the target file, the extent map defining how to construct the target file from deduplicated data segments in a deduplicated storage system, (2) receiving a request to take a snapshot of the target file corresponding to the configuration file, (3) copying the configuration file storing metadata for the target file and the extent map for the target file into a snapshot location within the non-virtual file system, and (4) transmitting a file reference request to the deduplicated storage system to add a file reference within the deduplicated storage system. Various other methods, systems, and computer-readable media are also disclosed.

摘要： A computer-implemented method for increasing restore speeds of backups stored in deduplicated storage systems may include (1) identifying a backup that includes data stored in at least one data container within a deduplicated storage system, (2) detecting a subsequent backup that includes additional data, (3) calculating an amount of duplication between the additional data included in the subsequent backup and the data stored in the data container, (4) determining that the amount of duplication between the additional data and the data stored in the data container is below a predetermined threshold, (5) identifying at least one additional data container to store the additional data instead of deduplicating the additional data with respect to the data container, and then (6) storing the additional data in the additional data container to facilitate increasing a restore speed of the subsequent backup. Various other methods, systems, and computer-readable media are also disclosed.
