As I have not once wrote, EMC deserve great applause for the approach to the subject releasing their products in the community version. This allows us to get acquainted with a number of solutions, including the latest one, which is Data Domain Virtual Edition. If you do not know what it is, I hasten to explain. It is a device that can function as a NAS or as a software tape library (VTL) and used as a backup repository (generally). Thanks to incredibly efficient deduplication algorithms, in a relatively small space we are able to cram a huge amount of data. Add to that the replication between devices, and several other useful features and you have a really interesting solution supported by most backup solutions (eg. EMC Avamar, Veeam Backup). In this year was released virtual version of Data Domain, which is distributed as a OVA file and includes a community license. This license allows the use of space 0.5T RAW (after deduplication safely accommodate 3T or more standard data), replication, encryption, and DD Boost ( support for external solutions).
