Select based on how quickly and frequently you restore backups and how long you plan to keep your backups in storage.
Many cloud storage vendors offer different storage classes / data tiers. Select based on how quickly and frequently you restore backups and how long you plan to keep your backups in storage. For backups that need quick and/or frequent restores, consider using the vendor’s hot storage as retrieval is fast and the most cost-effective. For long-term storage, consider moving data to archive storage. Restores can be slower, and there might be additional costs to retrieve data, but the storage costs are considerably lower – especially if you plan to keep the backups for years. Some vendors offer object lifecycle policies that can automatically move data between tiers, which reduces administration and lets you more easily realize cost savings.
