What is Immutable Storage? How is it Un-hackable? Why do I need it?
Immutable Storage consists of several technologies and processes to ensure data integrity and resilience. The technology that makes it easy to understand is WORM or Write Once Read Many.
Since immutable Storage writes the data in write-once-read-many form, the data blocks are Immutable!! The Blocks Can Not be altered, overwritten, or edited. Each vendor has different process and technology to further enhance Immutable Storage, encryption, serialization, fingerprints etc.. At BEST we choose NEXSAN Assureon for our Immutable Storage. In Assureon’s history Not a single file has been lost!!
One of the key use cases that has developed over the last few years is the fact Hackers are now attacking archives first to ensure once they encrypt your data you cannot simply restore and older copy from archival.
There are many additional use cases and don’t forget Audit / Compliance or other Regulatory requirements.
