I would like to delete my DB instance.before delete I will create final manual snapshot. I understood snapshot is not full backup.it is incremental.which means that only the data that has changed after your most recent snapshot saved .
so,I would like to know RDS restore DB from only final snapshot event if deleted other created all manual snapshot.
Please help me.Thanks a lot.
AWD RDS final manual snapshot are full or incremental ? final manual snapshot can be restore, event if deleted you taken all other manual snapshots
Although the snapshots are incremental, this process is done in a way that you can restore from the latest backup even if older snapshots are removed. So in short, you can restore your RDS database using your final manual snapshot. See the link for the underlying details.
Deleting previous snapshots of a volume does not affect your ability to create volumes from later snapshots of that volume - https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-deleting-snapshot.html
