20140201152 | SYSTEMS AND METHODS TO PROCESS BLOCK-LEVEL BACKUP FOR SELECTIVE FILE RESTORATION FOR VIRTUAL MACHINES - A data storage system protects virtual machines using block-level backup operations and restores the data at a file level. The system accesses the virtual machine file information from the file allocation table of the host system underlying the virtualization layer. A file index associates this virtual machine file information with the related protected blocks in a secondary storage device during the block-level backup. Using the file index, the system can identify the specific blocks in the secondary storage device associated with a selected restore file. As a result, file level granularity for restore operations is possible for virtual machine data protected by block-level backup operations without restoring more than the selected file blocks from the block-level backup data. | 07-17-2014 |
20140201153 | PARTIAL FILE RESTORE IN A DATA STORAGE SYSTEM - The data storage system according to certain aspects can implement partial file restore, where only a portion of the secondary copy of a file is restored. Such portion may be designated by one or more application offsets for the file. The system may provide an in-chunk index that includes mapping information between the application offsets and the secondary copy offsets. Chunks may refer to logical data units in which secondary copies are stored, and the in-chunk index for a chunk may be stored in secondary storage with the chunk. Because the mapping information may not be provided at a fixed interval, the system can search through application offsets in the in-chunk index to locate the secondary copy offset corresponding to the portion application offset(s). In this manner, the system may restore the designated portion of the secondary copy in a fast and efficient manner by using the in-chunk index. | 07-17-2014 |
20140201154 | SHARING OF SECONDARY STORAGE DATA - An information management system according to certain aspects allows users to share a portion of a file (e.g., a document) stored in secondary storage. The user may specify a portion of a secondary storage file to share and send a link to the portion to another user. The other user can access the shared portion from the link, and just the shared portion may be restored from secondary storage. The system according to certain aspects provides a native view of secondary storage data on a client computing device. The index data and/or metadata relating to secondary storage data may be stored in native application format for access via the native source application. | 07-17-2014 |
20140201155 | PARTIAL FILE RESTORE IN A DATA STORAGE SYSTEM - The data storage system according to certain aspects can implement partial file restore, where only a portion of the secondary copy of a file is restored. Such portion may be designated by one or more application offsets for the file. The system may provide an in-chunk index that includes mapping information between the application offsets and the secondary copy offsets. Chunks may refer to logical data units in which secondary copies are stored, and the in-chunk index for a chunk may be stored in secondary storage with the chunk. Because the mapping information may not be provided at a fixed interval, the system can search through application offsets in the in-chunk index to locate the secondary copy offset corresponding to the portion application offset(s). In this manner, the system may restore the designated portion of the secondary copy in a fast and efficient manner by using the in-chunk index. | 07-17-2014 |

Further, files in a backup image may be replaced based on current patch level data indicating a patched version of the file in the backup image is available. Further, upon a restore, if a patched file is available for a corresponding file in a backup image, the patched file may be retrieved from a patch source and used in place of the file that would have been restored from the backup image. | 12-11-2014 |
20140372379 | METHOD AND SYSTEM FOR DATA BACKUP - The present invention relates to a method, system, and computer program product for data backup, the method comprising: performing first chunking on current data by using the same chunking method as that used by original backup data to obtain a current chunk; calculating hash value of the current chunk; and acquiring, from a hash value table of the original backup data, an identifier of a matched chunk whose hash value is the same as the calculated hash value of the current chunk, and incrementing number of continuous matched chunks by one. Since the pertinence between original backup data and current data is maximally utilized, performance of de-duplication method can be efficiently improved. | 12-18-2014 |
20150363413 | TECHNIQUES FOR ENABLING COARSE-GRAINED VOLUME SNAPSHOTS FOR VIRTUAL MACHINE BACKUP AND RESTORE - A technique of backing up a workload in a virtual environment includes identifying one or more files that are associated with the workload.
