Fetch Available AWS Redshift Snapshots
There was a problem that the LLM was not able to address. Please rephrase your prompt and try again.
In AWS Redshift, snapshots are backups that capture the entire system state of a cluster at a specific point in time. Users may need to fetch or list these available snapshots for various reasons, such as monitoring, auditing, or planning a recovery operation. By fetching the list of snapshots, users can view details like snapshot creation time, source cluster, and snapshot size. Retrieving this list aids in effective snapshot management and ensures informed decision-making within the AWS environment.
