Some of the duplicate datastorage hierarchy, creating a one-step archive and one-step exists across multiple source systems, but most of the duplication is caused by storing repetitive full backup sets.
10 Using IBM data reduction solutions to manage more data with less infrastructureThe basic idea behind data deduplication is to store just one Data deduplication can and does occur at many points in thecopy of any data object, and place pointers to the single copy data creation and management life cycle. In general, these pointswherever duplicates are eliminated (see Figure 5). Some solu- of deduplication can be broken into source-side, where the datations do this at a ﬁle level, so that the ﬁles have to be exactly the is created, and target-side, where it is stored and managed.same to be deduplicated. This is often called single-instance Backup applications, for example, can perform source-sidestorage (SIS). Other solutions deduplicate data at a ﬁxed or deduplication by not transferring data that has previously beenvariable block length. IBM’s solutions use a blended approach backed up over the LAN or WAN, saving on bandwidth.based on the size of the data—ﬁle-based for smaller ﬁles, andvariable block for larger ﬁles. Most deduplication solutions run On the target side, the most popular use of deduplication is ina combination of checksum algorithms against the selected data virtual tape libraries, or VTLs.

Today, IBM offers two compelling data deduplication solutions. Tivoli Storage Manager includes both source and target data deduplication capabilities. On the source side, the backup agent Data Deduplication decides if it has sent a data block to the backup server in the past; Data Store Data Store Data Store if it has, it doesn’t send it again. It then also interrogates the backup server to determine if the same block has been backed up by another client. The net result is a reduction of data sent over the network, speeding backup processing. 1. Data chunks are 2. Signature values are 3. Duplicate data chunks evaluated to determine a compared to identify all are replaced with pointers unique signature for each duplicates to a single stored chunk, Virtualized server environments, such as VMware vSphere, saving storage space typically contain a large amount of duplicate data, considering the commonality of most virtual machine images.
