Final answer:
The best-suited on-premises storage solution should include a NAS for short-term backups, removable hard drives or magnetic tape for offsite security media, and magnetic tape or optical storage for long-term archives. This multi-layered approach ensures data accessibility, security, and compliance with archival policies.
Step-by-step explanation:
For an on-premises storage solution that meets the company’s requirement for short-term backups, offsite security media, and long-term archive storage without using a cloud solution, a combination of different storage technologies would be advisable.
Network-attached storage (NAS) systems would provide readily accessible short-term backup. For offsite security media, utilizing removable hard drives such as RDX technology, or magnetic tape storage, can provide a reliable and cost-effective solution for securely storing backups offsite. Finally, for long-term archival storage, magnetic tape or optical storage media, such as Blu-Ray discs in a robotic disc library, could be suitable as they offer durability and longevity.
A well-rounded strategy would involve a regular backup schedule, where the most recent data is backed up to the NAS frequently (e.g., daily), while less recent backups are periodically transferred to removable hard drives or tape and then securely transported to an offsite location. Periodically, data to be archived for long-term storage can be transferred to the respective archival storage medium.
