Does Bandwidth Expansion Affect the Running DRS Tasks?
When the cloud connection bandwidth is expanded, the bandwidth link needs to be re-established and the network is disconnected. Whether the network disconnection affects DRS tasks depends on the network disconnection duration and whether the source database IP address changes. For example, for the MySQL DB engine, if the network is disconnected for one day and the binlog of the source database is cleared within this day (the binlog clearing policy of MySQL is configured by the user), the task cannot be resumed. In this scenario, you need to reset the task. If the network is interrupted for a short period of time and the IP address of the source database in the VPN remains unchanged after the bandwidth link is changed, the system can continue to resume the task.
