Amazon Aurora | Backup and Restore Flashcards
How do I scale the compute resources associated with my Amazon Aurora DB Instance?
Backup and Restore
Amazon Aurora | Database
You can scale the compute resources allocated to your DB Instance in the AWS Management Console by selecting the desired DB Instance and clicking the Modify button. Memory and CPU resources are modified by changing your DB Instance class.
When you modify your DB Instance class, your requested changes will be applied during your specified maintenance window. Alternatively, you can use the “Apply Immediately” flag to apply your scaling requests immediately. Both of these options will have an availability impact for a few minutes as the scaling operation is performed. Bear in mind that any other pending system changes will also be applied.
How do I enable backups for my DB Instance?
Backup and Restore
Amazon Aurora | Database
Automated backups are always enabled on Amazon Aurora DB Instances. Backups do not impact database performance.
Can I take DB Snapshots and keep them around as long as I want?
Backup and Restore
Amazon Aurora | Database
Yes, and there is no performance impact when taking snapshots. Note that restoring data from DB Snapshots requires creating a new DB Instance.
If my database fails, what is my recovery path?
Backup and Restore
Amazon Aurora | Database
Amazon Aurora automatically maintains 6 copies of your data across 3 Availability Zones and will automatically attempt to recover your database in a healthy AZ with no data loss. In the unlikely event your data is unavailable within Amazon Aurora storage, you can restore from a DB Snapshot or perform a point-in-time restore operation to a new instance. Note that the latest restorable time for a point-in-time restore operation can be up to 5 minutes in the past.
What happens to my automated backups and DB Snapshots if I delete my DB Instance?
Backup and Restore
Amazon Aurora | Database
You can choose to create a final DB Snapshot when deleting your DB Instance. If you do, you can use this DB Snapshot to restore the deleted DB Instance at a later date. Amazon Aurora retains this final user-created DB Snapshot along with all other manually created DB Snapshots after the DB Instance is deleted. Only DB Snapshots are retained after the DB Instance is deleted (i.e., automated backups created for point-in-time restore are not kept).
Can I share my snapshots with another AWS account?
Backup and Restore
Amazon Aurora | Database
Yes. Aurora gives you the ability to create snapshots of your databases, which you can use later to restore a database. You can share a snapshot with a different AWS account, and the owner of the recipient account can use your snapshot to restore a DB that contains your data. You can even choose to make your snapshots public – that is, anybody can restore a DB containing your (public) data. You can use this feature to share data between your various environments (production, dev/test, staging, etc.) that have different AWS accounts, as well as keep backups of all your data secure in a separate account in case your main AWS account is ever compromised.
Will I be billed for shared snapshots?
Backup and Restore
Amazon Aurora | Database
There is no charge for sharing snapshots between accounts. However, you may be charged for the snapshots themselves, as well as any databases you restore from shared snapshots. Learn more about Aurora pricing.
Can I automatically share snapshots?
Backup and Restore
Amazon Aurora | Database
We do not support sharing automatic DB snapshots. To share an automatic snapshot, you must manually create a copy of the snapshot, and then share the copy.
How many accounts can I share snapshots with?
Backup and Restore
Amazon Aurora | Database
You may share manual snapshots with up to 20 AWS account IDs. If you want to share the snapshot with more than 20 accounts, you can either share the snapshot as public, or contact support for increasing your quota.
In which regions can I share my Aurora snapshots?
Backup and Restore
Amazon Aurora | Database
You can share your Aurora snapshots in all AWS regions where Aurora is available.
Can I share my Aurora snapshots across different regions?
Backup and Restore
Amazon Aurora | Database
No. Your shared Aurora snapshots will only be accessible by accounts in the same region as the account that shares them.
