Reparenting >>

The default settings created by set the binlog expire_logs_days to 3. Once the binlogs expire, you will not be able to bring up new empty replicas that can catch up to the current state.

If you are not using an online backup method like xtrabackup, the command will shut down the MySQL instance to perform the operation. The instance will be unavailable until the backup is finished, the restarted MySQL instance is pointed back at the primary and caught up on replication.

It is recommended that you also periodically backup your binlogs. Vitess does not natively support this ability. You will need to set this up yourself.

If a MySQL with existing data is restarted either manually or due to a failure, an automatic restore will not be performed. Instead, a recovery will be performed from the existing data files.

Please refer to the documentation for more information.
