You may receive alert emails reading could not connect to database. These are typically invalid messages. Under heavy load, the backup system may generate these messages even though there are no problems with the connection to the database. Adjust the setting under the Alertman section of the Settings file (Settings > System, Updates, and Licensing > General Configuration) to increase the number of minutes a connection cannot be made before generating an email. This setting is:
[Alertman]
DatabaseEmailTimeoutMins=60
// Minutes the system database must be down before an email is sent
Verify that the client has been registered on the backup system if restoring to an alternate system.
Verify the network settings are correct on the system. If the original system is still configured, verify that there is not a network conflict.
Verify that replication has been restarted on the system.
