SharedSnapshotQuotaExceededException: Handling Exceeded Shared Snapshot Quotas in AWS RDS
Are you facing issues with exceeding your shared snapshot quotas in Amazon Web Services (AWS) Relational Database Service (RDS)? Don’t worry; you are not alone. Many AWS RDS users encounter the “SharedSnapshotQuotaExceededException” error when their shared snapshot quota limits are reached. In this comprehensive guide, we will explore the causes, implications, and most importantly, how to handle this exception effectively.
Introduction to AWS RDS Shared Snapshots
Before diving into the specifics of SharedSnapshotQuotaExceededException, let’s familiarize ourselves with AWS RDS Shared Snapshots.
Shared snapshots provide a convenient way to share automated database backups across AWS accounts. These snapshots can be shared with other AWS accounts within the same region, allowing multiple users with separate accounts to access and restore backups. AWS RDS Shared Snapshots help you facilitate collaborative efforts, replicate data in multiple regions, or create logical backups across different accounts.
Understanding the SharedSnapshotQuotaExceededException
The exception SharedSnapshotQuotaExceededException is thrown when you reach the shared snapshot quota limit set by AWS for your account. This quota determines the maximum number of shared snapshots you can create and share with other AWS accounts within a specific region.
When the SharedSnapshotQuotaExceededException is encountered, you won’t be able to create any additional shared snapshots until you free up some space or request a quota increase from AWS. This exception serves as a safeguard to prevent potential abuse or overutilization of resources.
Reasons Behind Shared Snapshot Quota Exceeded Exception
There can be several reasons for encountering the SharedSnapshotQuotaExceededException in AWS RDS. Let’s explore the common causes:
1. High Demand for Shared Snapshots
The quota restriction is in place to maintain resource utilization and prevent scalability issues. It’s possible that the increased demand for shared snapshots has pushed your account’s usage beyond the set threshold, resulting in the quota being exceeded.
2. Insufficient Cleanup or Retention Policies
If you are not regularly cleaning up or purging old or unnecessary shared snapshots, it’s easy to accumulate snapshot data and eventually exceed your quota. Additionally, retaining shared backups for extended periods can lead to limited space for creating new backups.
3. Inadequate Initial Quota
New AWS accounts usually have a lower initial shared snapshot quota. As your usage and requirements grow, this initial quota might not be sufficient. It’s crucial to monitor your usage and proactively request an increase in the shared snapshot quota to avoid running into this exception.
Handling SharedSnapshotQuotaExceededException
Encountering the SharedSnapshotQuotaExceededException can be frustrating, but there are several ways to handle this exception effectively. Let’s explore the recommended strategies:
1. Identifying Resource Usage and Cleaning Up
The first step towards resolving the quota exceeded exception is identifying the resource usage and reclaiming snapshot space. The following AWS CLI command displays the list of shared snapshots and their associated accounts:
1
aws rds describe-db-cluster-snapshots --query "DBClusterSnapshots[*].[DBClusterSnapshotIdentifier,SharedAccounts]"
Review the shared snapshots and verify if any unnecessary or outdated snapshots can be safely deleted. Additionally, consider revising your backup retention policy to prevent excessive snapshot accumulation in the future.
2. Requesting a Quota Increase
If regular cleanup is not sufficient or you anticipate an increased demand for shared snapshots, submitting a request to increase your shared snapshot quota is advisable. AWS provides a simple process to request a quota increase.
- Open the AWS Support Center.
- Create a new case and select “Service limit increase” as the category.
- Provide detailed information about your use case, explaining the need for a higher shared snapshot quota.
- Submit the request and wait for AWS to review and approve it.
AWS usually responds to such requests promptly, addressing your requirements and increasing the shared snapshot quota accordingly.
Conclusion
In this in-depth guide, we delved into the SharedSnapshotQuotaExceededException of AWS RDS and explored the causes behind encountering this exception. We learned about the concept of shared snapshots, the significance of quota limits, and how to handle exceeded shared snapshot quotas effectively.
To avoid facing a shared snapshot quota exceeded exception, it is crucial to regularly monitor your usage, clean up unnecessary snapshots, and submit a quota increase request if required. By implementing these best practices, you can ensure smooth operations and scalable collaboration across multiple AWS accounts.
Remember, efficient resource management is key to maintaining a well-structured AWS RDS infrastructure. By understanding and addressing shared snapshot quota limits, you can make the most of AWS’s collaborative features and mitigate potential quota exceeded exceptions.
