Detail Summary-AWS RDS Databases- Part 2

Here I would present More details on Back up strategies of the AWS RDS

RDS Backups

As RDS Supports Automatic backups, daily back up happens on 30 minute windows in general, these are enabled by default with 7 day retention period. if we do no need back up set to disable by setting retention to 0. we can set retention period max to 35 days. The first back up is full and the next are incremental and these are saved in S3 buckets.

The data is stored in S3 and you cannot see them in AWS S3 console as AWS owns these buckets internally. you might experience a IO suspension if we are on single AZ when backups are running.

There are two types of backups.

Backups -Automated, incremental, retention (0–35 days)

Snapshots - Manually triggered, full backup, retain as long as we want, does not support PITR.

We can use AWS Backup service or AWS lambda to do manual backups.

Copying and sharing the Backup.

we can copy the automated backups or snapshots across region or across accounts. For copying across accounts there is a cost incurred.

Copying and sharing encrypted snapshots.
