A relational database can be quickly and easily deployed, managed, and scaled with the help of Amazon’s Relational Database Service (Amazon RDS). It lets you focus on your apps and business rather than on the time-consuming responsibilities of database maintenance while still providing scalable storage at a low cost.
Your database can be backed up automatically, and your database software can be kept up to date, both using Amazon RDS. The ability to quickly increase or decrease the size of your database’s storage space or processing power is a major perk of using a relational database. In addition, for read-intensive database workloads, AWS Backup RDS makes it simple to employ redundancy to increase database accessibility, strengthen data longevity, or expand beyond the limits of a single database instance. Just like every other Amazon Web Service, Elastic Compute Cloud requires no initial financial outlay and charges only for the resources actually utilized.
AWS backup RDS options for enterprise companies
Database backup automation tools are built into Amazon RDS. When you back up your database with Amazon RDS, the entire DB server is backed up, not just the databases you choose. Amazon RDS allows you to set a backup frame for scheduled backups, make snapshots of your database instances, and distribute and replicate those backups across multiple accounts and geographic regions.
With Amazon RDS, you may back up and restore your database instances in two distinct ways:
A DB instance can be restored to any previous point in time (PITR) thanks to automated backups. When you initiate a new database instance, automated backups are enabled immediately.
When you create a database instance in Amazon RDS, you can choose a backup window during which Amazon RDS will execute a full backup of your data once per day. Automatic backups can be set to keep data for as long as 35 days if desired. Every 5 minutes, Amazon RDS will transfer the database instance’s transaction data to Amazon S3. When restoring a database instance, Amazon RDS uses both your daily backups and your database’s transaction logs.
You can use the DescribeDBInstances API method to get the most recent restore point for your database instances. As an alternative, you can check the database’s description in the Amazon RDS management portal.
You can initiate a PITR to have your database instance restored to a specific time by using the transaction logs in conjunction with the most recent daily backup.
Database snapshots are consumer backups that may be used to roll back your database instance to a specific point in time. After saving your previous state, you can always go back to it.
AWS Backup methods
AWS Backup, which also offers other capabilities, supports both of these backup methods for Amazon RDS. You can use AWS Backup to create a standardized backup plan for your Amazon RDS databases, and you can use the user-initiated instance backup tools if you need to create a specific backup plan for a specific database.
During the backup window of your DB instance, Amazon RDS will automatically create and store backups of your DB instance. Rather than just backing up the databases themselves, RDS produces a snapshot of the complete storage volume containing your database instance. According to the backup retention period you set, RDS will save automated backups of your DB instance. Should the need arise, you can restore your database to any moment within the time frame of your backups.
Database copies and backups can be made both automatically and manually, and manual backups can be shared. Please refer to Copying a DB Snapshot for details on how to duplicate a database backup. Learn more about the specifics of database snapshot sharing by reading Sharing a DB Snapshot.
