As its primary means of data reduction, Veeam uses a performance-optimized combination of deduplication and compression, allowing a single backup proxy to process data streams at 1GB/s during both vSphere or Hyper-V backups and restores — up top 10x faster than the competition!
Veeam performs deduplication at the job level at both the source (i.e., at backup proxy) and the target (i.e., at backup repository):
You can choose from four different deduplication options based on backup size and connection speed to backup target ― so you can optimize both backup size and job performance.
Veeam also offers five levels of compression that allow you to find the right balance of storage consumption and backup proxy load, which, in turn, can affect performance. This includes a dedupe-friendly compression designed for deduplication storage devices.
Veeam’s built-in deduplication and compression work hand in hand to provide the best possible ratio of storage savings to backup performance. Unlike compression, inline deduplication is known to be very taxing on backup performance. Veeam ensures performance by using fairly large block sizes for deduplication, which allows for much better compression levels. The resulting data-reduction ratio is comparable to the ratio achieved by most advanced deduplication technologies — but with a much smaller processing overhead!
Deduplication appliance-friendly compression — the best of both worlds More ways to save storage and reduce network traffic.
In addition to well-known deduplication and compression techniques, Veeam introduces BitLooker, a new and advanced procession capability that further reduces vSphere or Hyper-V backup file size, facilitating faster data transfers and optimizing storage usage by up to 20%:
