Lab 4 - Restore from Snapshot
The last option to migrate a database from x86-64 to Graviton is to restore a database snapshot to a Graviton instance, creating a new database, and leaving the existing database in place.
An alternative lab to this one exists here
Check for an existing snapshot or create a new one
- The default settings should have created a snapshot at DB creation time. Select Snapshot from the RDS menu on the left, and click on the Automated tab to see which snaphots are available.
- You also have an option to create a snapshot manually with the Take Snapshot button. Refer to the RDS documentation
to take a manual snapshot if required.
Use the snapshot to create a new database running on Graviton
- Select the checkbox next to the snapshot you want to restore, for this lab we are going to use the mariaDB instance created in the preparation
step. The snapshot should follow the format
- From the actions dropdown menu, choose Restore
- Enter a new name for the database instance identifier, e.g.
- Under Instance configuration select the radio button Burstable classes (includes t classes)
- Select db.t4g.micro
- Leave other settings at defaults and click the Restore DB Instance button
- The database will now be created from the snapshot
- Once the database is in Available status the lab is complete and you can move to cleanup.
