Question

A financial services firm retains seven years of transaction data to satisfy regulatory obligations. Most queries touch only the last 90 days, but the entire dataset currently resides on high-performance production storage that is nearing capacity. The risk practitioner is asked to advise on managing this data through its lifecycle. Which recommendation BEST balances cost, performance, and risk?

Accepted Answer

Move data older than 90 days to a lower-cost archival tier while preserving integrity, access controls, and retrievability to meet the retention requirement

Answer

Delete all transaction data older than 90 days to free capacity, since it is rarely queried

Answer

Purchase additional high-performance storage so all seven years remain on production tier for uniform fast access

Answer

Compress the older data in place on production storage and remove the access controls to reduce management overhead
