This kind of issue defines why a site should have a storage architect, to
select the best overall implementation of such storage, including safeguarding
against problems. Some storage requires only failsafe protection represented
in RAID 1 or RAID 5. Some requires multi-generation file-level backup for
recoverability from logical errors and tampering. Then there are disaster
recovery requirements of the site. The site storage specialist would also have
knowledge of the characteristics of the data at the site, and be versed in
regulatory requirements, for privacy and retention factors to be considered in
the overall solution. The storage specialist would also be up on the latest
storage technologies and products, to select the most appropriate to the needs.
The days of a company department acquiring a clump of disk and implementing it
in an arbitrary manner are long gone...or should be.
