Every administrator knows when evaluating the annual comparison, double-digit growth rates are often recorded for data volumes. IDC forecasts a five-fold increase in the amount of data generated annually in the coming years. Usually, IT managers react to this by purchasing new storage capacities - and this process puts themselves offside in the long term. In addition, companies are legally obliged to regularly and reliably implement suitable data backup routines. But how remains this from possible against the background of growth scenarios without building up a complex, new IT infrastructure for it?
This is where SEP sesam Si3 deduplication comes in. Efficient Si3 inline deduplication uses variable block lengths, is high-performance and is performed simultaneously with the backup processes. There is no staging area for buffering the data. Deduplicated data consists of two elements: A pool of data blocks and a catalogue that references the pool of data blocks. This catalogue knows the original file name and the reference to the data blocks it contains. When an identical file is backed up repeatedly, only one entry is written to the file catalogue with a reference to the blocks which are already stored in the pool. The deduplication solution divides the data blocks within the file like a template. SEP sesam Si3 deduplication is the basis for bandwidth-saving replication of data between distributed company locations or data centers.
