# Perform a LAN Backup using MS Networking

NuPoint UM supports manual and scheduled backups of all application data from the NuPoint UM server(s) using Microsoft Networking or a FTP server on the customer's LAN. Each backup is a full and independent backup of NuPoint UM data, and does not include existing MSL configuration data. You perform backups over the LAN to an FTP server or a Microsoft network share.

NuPoint UM provides a system restore capability from the LAN archive to the server. You can restore data using FTP / MS Network interchangeably, provided that you use the same directory path for both. The format of the backed up data is the same, regardless of whether you backed it up using FTP or MS Networking.

Backing up NuPoint UM data can take a few seconds or up to several hours. Factors that influence the duration include

- The nature of the files to be backed up and the amount of information being transferred. Messages, names, and greetings are large files and significantly increase the backup duration.

- The network speed: the throughput of the network between the NuPoint UM system and the storage server.

- The processing speed of the storage server.

### Before You Begin

- Ensure the folder or drive to be used for LAN backups is shared with Read/Write permission for the userid configured in the NuPoint Unified Messaging menu. Failure to do so will result in errors.

- Ensure the Windows PC has sufficient disk space available for the backup.

- If you have added local hostnames for VPIM servers to the Mitel Standard Linux server, the hostnames are not backed up by the LAN backup procedure. To back up local hostnames for VPIM servers on the Mitel Standard Linux server, you must back up the Mitel Standard Linux server settings before you perform the LAN backup procedure. For information about backing up the Mitel Standard Linux server, refer to the Mitel Standard Linux Installation and Maintenance Guide available at Mitel OnLine.

- Ensure the network connection is functioning and is stable.

- The file size limit for LAN backups is set by the destination file system: 4 GB for a FAT32, 2 TB for NTFS, and 16 GB to 16 TB for ext3 (depending on file system block size). The current MSL ext3 block size is 4096 bytes which allows file sizes of 2TB.

- For Active/Active and Active/Passive systems, ensure the backup is restored to the correct server (for example, the server1 backup must be restored to server1) in order to maintain cluster and ILO information.

- Configure the MS Network Share for backups and restores.

To specify network, login, and default backup settings for the Microsoft Network destination server

1. Access Text console and connect to the NuPoint UM node.

2. Log in as "root" and type the admin password.

3. To access the MS Networking Backup menu, select S (System Maintenance), L (NPM Backup Menu), and M (Lan Backup using MS Networking).

4. In the MS Networking Backup Menu, configure the following settings:

1. - (I) MS Network Destination Hostname = [enter the IP address of the server to which you will back up the data (for example, 10.33.63.111).]

   - (A) MS Network Shared Path = [enter the path to the shared folder on the PC where the data will be backed up]

   - (U) MS Network User Id = [enter the user name for the local account on the PC where the data will be backed up.]

   - (P) MS Network Password = [enter the password for the local account on the PC where the data will be packed up.]

   - (D) Backup Path = [enter the path to the folder where the data will be backed up.] You specified the name of the root folder in Step 1 of Configuring the MS Network Share for backups and restores.

   - (M) Backup Messages (Y/N)? = [enter Y (yes) or N (no) to indicate whether you want to restore the mailbox messages.]

   - (N) Backup Names and Greetings (Y/N)? = [enter Y (yes) or N (no) to indicate whether you want to restore the mailbox names and greetings.]

   - (F) Backup Fax Coverpages (Y/N) = [enter Y (yes) or N (no) to indicate whether you want to restore the Fax cover pages.]

Note: The system configuration is automatically backed up to the MS Networking server.

5. Select B (Perform Backup) to begin the backup process. When the backup is complete, under General information the Status line confirms if the backup was completed successfully.

6. Exit to the Main Menu and quit Text console.

### Troubleshooting a LAN Backup (MS Networking)

- If the backup fails (times out, broken connection), you are given a choice to either start it again from beginning or to resume the last backup. The time-out value in case of a broken LAN connection is 1 minute.

- The following scenarios are possible during a LAN Backup/Restore:

- LAN connection failure - The backup stops after a time-out of 1 minute. In this case, you must restart the backup manually. The system prompts you to either resume the backup or restart it from the beginning. The log file will specify the error encountered.

- Windows server share not available - This scenario is same as LAN connection failure. See above.

- Remote disk full - The backup process can not find out if the disk space is full or not. The processes will simply log the error that it could not copy the file(s). Attempts to resume the backup may continue failing. Ensure that enough disk space is available on the remote server.

- Login failure - Backup will stop immediately, indicating the appropriate error in the log file.
