Somebody needs to create a system that encompasses continuous data protection, deduplication and cloud storage.  Many vendors have various parts of such a solution but none to my knowledge has put it all together. Why CDP, deduplication and cloud storage? We have written about cloud problems in the past (eventual data consistency and what’s holding back [...]

Deduplication is a mechanism to reduce the amount of data stored on disk for backup, archive or even primary storage.  For any storage, data is often duplicated and any system that eliminates storing duplicate data will be more utilize storage more efficiently. Essentially, deduplication systems identify duplicate data and only store one copy of such [...]
