20090100230 | System and method to protect data stored in a storage system - In an example of an embodiment of the invention, a system for recording data generated by a client server and transmitted to a storage system is provided. The system comprises a storage system and a processor located remotely from the storage system and linked to the storage system via a network. The processor determines that a selected data processing operation is to be performed with respect to data stored in the storage system, and determines that a record of at least some of the data stored in the storage system is required prior to performing the selected data processing operation. The processor also generates a command comprising a request to generate a record of the at least some of the stored data, the command being generated in accordance with a well-known standard, and transmits the command to the storage system to generate the record, via the network in accordance with Internet Protocol (IP). Examples of other systems and methods are also disclosed. | 04-16-2009 |
20100011181 | Methods for synchronizing storage system data - In accordance with one example, a method for comparing data units is disclosed comprising generating a first digest representing a first data unit stored in a first memory. A first encoded value is generated based, at least in part, on the first digest and a predetermined value. A second digest representing a second data unit stored in a second memory different from the first memory, is generated. A second encoded value is derived based, at least in part, on the second digest and the predetermined value. It is determined whether the first data unit and the second data unit are the same based, at least in part, on the first digest, the first predetermined value, the first encoded value, and the second digest, by first processor. If the second data unit is not the same as the first data unit, the first data unit is stored in the second memory. | 01-14-2010 |
20110231367 | System and method for backing up data - A hash-optimized backup system and method takes data blocks and generates a probabilistically unique digital fingerprint of the content of each data block using a substantially collision-free algorithm. The process compares the generated fingerprint to a database of stored fingerprints and, if the generated fingerprint matches a stored fingerprint, the data block is determined to already have been backed up, and therefore does not need to be backed up again. Only if the generated fingerprint does not match a stored fingerprint is the data block backed up, at which point the generated fingerprint is added to the database of stored fingerprints. Because the algorithm is substantially collision-free, there is no need to compare actual data content if there is a hash-value match. The process can also be used to audit software license compliance, inventory software, and detect computer-file tampering such as viruses and malware. | 09-22-2011 |
20110258162 | System and method for identifying and mitigating redundancies in stored data - In an example of an embodiment of the invention, a repeating pattern is identified within stored data comprising a plurality of data files, each data file comprising at least a header section and a data section stored in an unknown format. At least one occurrence of the repeating pattern is identified as a header section of a respective data file, and a data section of the respective data file is identified based, at least in part, on a location of the at least one occurrence of the repeating pattern. The identified data section of the respective data file is backed up. Systems are also disclosed. | 10-20-2011 |
20120278570 | METHODS FOR SYNCHRONIZING STORAGE SYSTEM DATA - In accordance with one example, a method for comparing data units is disclosed comprising generating a first digest representing a first data unit stored in a first memory. A first encoded value is generated based, at least in part, on the first digest and a predetermined value. A second digest representing a second data unit stored in a second memory different from the first memory, is generated. A second encoded value is derived based, at least in part, on the second digest and the predetermined value. It is determined whether the first data unit and the second data unit are the same based, at least in part, on the first digest, the first predetermined value, the first encoded value, and the second digest, by first processor. If the second data unit is not the same as the first data unit, the first data unit is stored in the second memory. | 11-01-2012 |
20130185261 | System and Method for Identifying and Mitigating Redundancies in Stored Data - In an example of an embodiment of the invention, a repeating pattern is identified within stored data comprising a plurality of data files, each data file comprising at least a header section and a data section stored in an unknown format. At least one occurrence of the repeating pattern is identified as a header section of a respective data file, and a data section of the respective data file is identified based, at least in part, on a location of the at least one occurrence of the repeating pattern. The identified data section of the respective data file is backed up. Systems are also disclosed. | 07-18-2013 |
20130238850 | System and Method for Storing Data and Accessing Stored Data - In one example of a method to access data, selected data stored in a virtual tape library (“VTL”) maintained in a selected format in a first non-tape storage medium is examined. One or more first directories and one more first files are identified within the selected data. One or more second directories, and one or more second files, comprising information identifying at least one of the one or more first files, are generated and are stored in a second non-tape storage medium. A request specifying at least one of the one or more second files is received from a device, and information identifying at least one of the one or more first files is retrieved from the specified second file. The at least one first file is accessed based at least in part on the information, and data from the at least one first file is provided to the device. Systems are also disclosed. Methods and systems to enable users without system administrator rights to access and store data in a backup storage system are also disclosed. | 09-12-2013 |
20140181445 | SYSTEMS AND METHODS FOR PROCESSING INSTRUCTIONS WHILE REPAIRING AND PROVIDING ACCESS TO A COPIED VOLUME OF DATA - A volume of data is copied from a first location to a second location. A procedure to repair a volume of data is initiated. A first instruction associated with the repair procedure is selectively redirected to a staging storage, based on a determination that the first instruction relates to an action that makes a change to the volume. A second instruction is selectively redirected to one of the staging storage and the volume, based on data stored in the staging storage. | 06-26-2014 |
