In today’s scenario, every IT Firm tries to optimize its expenditure spent on backup storage to work efficiently. That’s why they frequently inquire about the expected Amazon RDS backup storage cost, particularly new customers who are commencing their cloud journey. They frequently wish to predict and budget for database backup purposes depending on their business requirements. and to estimate the costs it is crucial to know about the variables that affect the final cost of the backup.
The purpose of this blog is to briefly explain to you the variables that affect the monthly cost of backup storage. Let’s get started.
Different variables affecting the monthly cost of backup storage:
Database storage size- This denotes the allocated database storage of your instances inside a region. For example, Amazon AWS offers up to 1.8 TiB-month of backup storage at no extra charge if you have an active Amazon RDS for Oracle instance with 1 TiB of provisioned storage and an active Amazon RDS for SQL Server instance with 800 GiB of provisioned storage.
Database workload patterns- The first snapshot comprises blocks that will be utilized for your data. As an illustration, if a database is configured with 1 TiB of storage, your data may take up 700 GiB of that space, leaving 30% of that capacity available for use. The only blocks contained in successive snapshots that have changed since your most recent snapshot are progressive (as long as the whole snapshot is accessible).
Retention period- Retention time for automated backups ranges from 0 to 35 days. Automatic backups are disabled and all previous automated backups for that instance are deleted when the backup retention period is set to 0. Most likely, you won’t be charged for backup storage if your retention period is set to 1 day.
Frequency of user-initiated snapshots (manual snapshots)- You can start manual snapshots of your instances for long-term storage in addition to automated backups. Manual backups are excluded from the designated retention period. Manual snapshots need more backup storage the more frequently you use them, which might result in higher backup storage costs.
Other instances, their database storage size, and backup policies in the Region- Due to the fact that the allotted non-chargeable backup storage capacity is based on the combined database storage of all instances within a region, other instances and their backup and retention policies within the account will affect the monthly cost of your backup storage. The default configuration might potentially result in extra costs if the backup and retention strategy is uniform across all instances.
