Point In Time Recovery or PITR - is an enhanced version of the on-demand backup and restore feature, providing you with the ability to perform point in time recoveries. This feature is extremely handy in situations when you’re modifying data and want a safety net in place for the situation where your data modifications didn’t result in the way they should have. With PITR in place, you can simply restore back to a specific time. PITR takes the burden away of having to plan backup schedules, etc.
Point In Time Recovery operates at the table level, and when enabled provides you with the ability to perform a point in time recovery for any time between the current time and the last 35 days. This feature needs to be enabled as it is disabled by default. Once enabled you can request a recovery by specifying a date and time with second precision or granularity. The restoration will always be performed into a new table - of which you specify the new table name at time of restoration request. Table restoration can be performed in the same region as the original table, or into a different region altogether.
