# MNM Backup and Restore - Conditions

The following conditions apply:

- MNM Backup and Restore is only available in an SDS Administrative Group that supports Multi-Node Management (MNM) applications.

- To support database backups from multiple elements, you must have an external FTP or SFTP server in the network where the system can save the backups. You must configure the path to the FTP or SFTP server and other FTP or SFTP server parameters in the External FTP Server form.

- By default, the FTP or SFTP Server Parameters are shared by SDS among the elements at the "Admin Group Members" scope. If you want to specify different FTP or SFTP servers for different elements, disable the sharing of the FTP or SFTP Server Parameters by setting the sharing scope to "None" in the SDS Form Sharing form.

- You need to ensure that the FTP or SFTP server

- is working properly and that there is sufficient disk space on the server for the database files

- supports the required number of concurrent client sessions. To perform database backups from multiple elements a concurrent client session is required for each element in the Administrative Group. For example, if the Administrative Group has 10 elements, the FTP or SFTP server must support a minimum of 10 concurrent client sessions.

- You can still use the Backup form in the System Administration Tool to save the database of the local system to the hard drive of the System Administration Tool client PC.

- The backup and restore databases will include the following FTP or SFTP server information:

- IP address

- Port

- Login user name

- Login password

- Path (optional)

- The list of MNM element members are saved in the database backup file and can be restored from the backup file.

- The MNM Backup and Restore application does not affect the backup and restore functions that are available from the MiVoice Business Software Installer Tool.

- If for any reason the backup process fails on a node, a Backup Failure alarm is generated for that node. The alarm is local to the node that failed; it is not generated for any remote nodes. However, you can use the Admin Group Alarm Summary form to view possible Backup Failure alarms on the remote nodes. For more information, see Backup Failure Notification.
