Which of the following backup strategies is MOST cost-effective for long-term storage in the cloud?
The Correct Answer is: D. Archival cold storage
Archival cold storage is specifically designed for long-term data retention at a lower cost. It stores infrequently accessed data such as backups, compliance records, and archives, making it ideal for organizations aiming to reduce storage expenses. Though retrieval times may be longer, its affordability and scalability make it the most cost-effective cloud backup strategy for long-term storage.
Why the other options are incorrect:
A. Daily full backup
Daily full backups consume significant storage and bandwidth, resulting in high costs over time. While reliable, they are not optimized for long-term, infrequent access.
B. Weekly differential backup
Differential backups save space compared to daily full backups but still require more storage than archival solutions and are not as cost-effective for multi-year retention.
C. Snapshot backup
Snapshots are ideal for short-term recovery and rapid rollbacks but are not suitable or optimized for low-cost, long-term archival storage. Their costs accumulate over time.
