Is deduplication of data safe?
It’s very difficult to harden a storage system so that it has the resiliency that you need to remain operational through a drive failure or a power failure. Find out what technologies the deduplication solution has to ensure data integrity and protection against system failures. The system should tolerate deletions, cleaning, rebuilding a drive, multiple drive failures, power failures – all without data loss or corruption. While this is always important in storage, it is an even bigger consideration in data protection with deduplication. With deduplication solutions, there may be 1,000 backup images that rely on one copy of source data. Therefore this source data needs to be kept accessible and with a high level of data integrity. While the need is higher for data integrity in deduplication storage, it also offers new opportunities for data verification. In Data Domain’s case, we take full advantage of the small resulting data size to do a complete internal test recovery, end to end, t
