Meaning
Data preservation technology prevents the alteration or deletion of information once it has been recorded to a physical or virtual medium. This write once storage evidentiary is used to maintain immutable records for legal and regulatory compliance. It ensures that the data remains in its original state for the duration of its retention period.
The technology is limited by the physical or logical capacity of the storage device.
Immutability Logic
Forensic requirements in regulated industries demand that logs remain in their original state for several years. When write once storage evidentiary systems are used, the hardware or software creates a permanent lock on the data blocks. This lock ensures that even a person with high-level access cannot modify the files to hide evidence of an action.
It provides a level of certainty that standard storage systems cannot match. The integrity of the record is maintained through cryptographic hashing and physical write protection.
Storage Durability
Discovery of truth during a legal dispute depends on the availability of untampered logs. The use of write once storage evidentiary provides a foundation for trust in the digital records produced by the company. It eliminates the possibility of retrospective data manipulation.
This durability ensures that the evidence is available when it is needed.
Forensic Value
Regulatory compliance for financial transactions often specifies the use of immutable storage. Data kept on write once storage evidentiary meets the strict standards of audit agencies. It protects the company from claims of evidence tampering.
This value is measured by the defensibility of the records in a court of law.
