amazon-redshiftHow do I restore a snapshot to an existing Amazon RDS instance?
To restore a snapshot to an existing Amazon RDS instance, you can use the AWS CLI.
First, you will need to create a new DB instance from the snapshot. To do this, use the aws rds restore-db-instance-from-db-snapshot
command, which will create a new instance from the snapshot. For example:
aws rds restore-db-instance-from-db-snapshot \
--db-instance-identifier my-restored-instance \
--db-snapshot-identifier my-snapshot
This command will create a new DB instance named my-restored-instance
from the snapshot my-snapshot
.
Next, you will need to modify the existing instance to use the restored instance as a source. To do this, use the aws rds modify-db-instance
command, which will modify the existing instance to use the restored instance as a source. For example:
aws rds modify-db-instance \
--db-instance-identifier my-old-instance \
--source-db-instance-identifier my-restored-instance
This command will modify the existing instance my-old-instance
to use the restored instance my-restored-instance
as a source.
Finally, you will need to delete the restored instance. To do this, use the aws rds delete-db-instance
command, which will delete the restored instance. For example:
aws rds delete-db-instance \
--db-instance-identifier my-restored-instance
This command will delete the restored instance my-restored-instance
.
Once all of these steps have been completed, the existing instance will be restored from the snapshot.
