Abstract: Methods and systems for recovering a host image of a client machine to a recovery machine comprise comparing a profile of a client machine of a first type to be recovered to a profile of a recovery machine of a second type different from the first type, to which the client machine is to be recovered, by a first processing device. The first and second profiles each comprise at least one property of the first type of client machine and the second type of recovery machine, respectively. At least one property of a host image of the client machine is conformed to at least one corresponding property of the recovery machine. The conformed host image is provided to the recovery machine, via a network. The recovery machine is configured with at least one conformed property of the host image by a second processing device of the recovery machine.

Abstract: Methods and systems for deduplicating data by a system having a first storage device and a second storage device to store deduplicated data are described, wherein data is retrievable from the first storage faster than data is retrievable from the second storage. The first storage may be an SSD device. Data is received data for deduplication and deduplicated. It is determined whether to store the received data in the first storage or the second storage, and the data is stored in the determined location. If the first storage is full, data may be moved to the second storage to make room for data to be stored in the first storage. One or more factors may be used to determine whether to store the received data in the first storage and which data to move out of the first storage, if necessary. Retrieval methods and systems are also described.

Abstract: Systems and methods of data deduplication are disclosed comprising generating a hash value of a data block and comparing the hash value to a table in a first memory that correlates ranges of hash values with buckets of hash values in a second memory different from the first memory. A bucket is identified based on the comparison and the bucket is searched to locate the hash value. If the hash value is not found in the bucket, the hash value is stored in the bucket and the data block is stored in a third memory. The first memory may be volatile memory and the second memory may be non-volatile random access memory, such as an SSD. Rebalancing of buckets and the table, and use of additional metadata to determine where data blocks should be stored, are also disclosed.

Abstract: Systems and methods of writing to a storage system comprise analyzing a plurality of snapshots of data blocks of a storage device and determining a likelihood that a next first write will be to a respective data block based, at least in part, on the analyzed plurality of snapshots. A snapshot is then taken of a selected data block based, at least in part, on the respective likelihood for the selected data block, before receiving a write request to the selected data block. A write request to a respective data block is then received and data is written to the respective data block, if the snapshot of the respective data block had been taken. If the snapshot of the respective data block had not been taken, then a snapshot of the respective data block is taken. Then data is then written to the respective data block.

Abstract: 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.

Abstract: 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.

Abstract: 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.
