Storage Backup

Last update: Thursday, 13. Mar 2014

This article refers to the Barracuda Message Archiver release 3.1 or higher.

In this article:

The Message Store of the Barracuda Message Archiver should be backed up just as you would back up your data on any other data storage device. Data is stored on the share in files of about 1GB in size. All files in all shares must be backed up. Be aware that although you can back up the files, you must contact Barracuda Networks Technical Support in order to restore any of the data.

Backups can be saved to any FTP or SMB location to which the Barracuda Message Archiver has access. To create internal storage volume backups, you can enable Show Local Backup Options on the ADVANCED > Backup page to display the backup options.

Backup of Archives

In the Backup of Archives section, you can enable NFS or SMB access to the message store, and create local storage backups. For more information, refer to Archived Data Backup.

  • For backups via SMB, the username used to connect to the published SMB share is always smb, but you can optionally specify a workgroup name and an access password. 
  • When publishing the data partition via NFS, please contact Barracuda Networks Technical Support for assistance in restricting access to the NSF share by IP address.

The Message Store can be made available as an NFS or SMB share on your network. Provide the following information to enable any share:

  • Back Up Archives via NFS – Set to Yes to enable access to the Message Store as NFS shares.
  • Back Up Archives via SMB – Set to Yes to enable SMB access to the Message Store.
  • Workgroup – Enter the name of the Workgroup that the share is to be a part of.
  • Password – Enter the password required to access the network share.
NFS Shares

The number of shares on the Barracuda Message Archiver can vary. All models will have share number 1, while higher model numbers may have additional shares. Possible share configurations include:

share numbers
1
1, 2
1, 2, 3, 4

Enabled NFS shares can be mounted as: 
host:/BMA-NFS-# 

where host is the hostname or IP address of your Barracuda Message Archiver, and # is the share number.

Users of NFS v4 must also include the option -o vers=3 in the mount command.

Example:

If the IP address of your Barracuda Message Archiver is 192.168.1.10, to mount the second share you issue the command:
mount -t nfs 192.168.1.10:/ BMA-NFS-2 dir
where dir is the path where the share is to be mounted.
Similarly, for NFS v4 users, use the command:
mount -t nfs -o vers=3 192.168.1.10:/BMA-NFS-2 dir

SMB Access

If SMB access to the Message Store is enabled, it can only be accessed by the username smb using the Password specified above.

SMB shares enabled for backing up the Message Store are not the same as the shares used for other purposes, such as importing .pst files. Refer to the BASIC > Administration page to enable SMB shares for other uses.

The number of shares on the Barracuda Message Archiver can vary. All models have share number 1, while higher model numbers may have additional shares. Here are the possible share configurations:

share numbers
1
1, 2
1, 2, 3, 4

Enabled SMB shares can be reached at:
\\host\BMA-SMB-# 

where host is the hostname or IP address of your Barracuda Message Archiver, and # is the share number.

If you are already connected to another SMB share on your Barracuda Message Archiver, you may need to specify the host name instead of the IP address.

Example:

If the IP address of your Barracuda Message Archiver is 192.168.1.10, to connect to the second share use:
\\192.168.1.10\BMA-SMB-2

Desktop Backups

Backups can be made of the configuration of your Barracuda Message Archiver to a file on your local machine. These files can be used for backup purposes, as well as for uploading to another Barracuda Message Archiver running the same or higher firmware version. Backups can be created manually to be saved to your desktop as needed, or created automatically to be saved onto a storage server on a regular basis.

Select a file in the Available Backups table in the Cloud-Based Configuration Backups section, and then click  Backup in the Desktop Backup section to initiate the creation of a configuration backup file to be saved locally. The default filename is in the format BAR-MA- serial-date -Config_Backup.bak, where:

  • serial is the serial number of the unit
  • date is the date and time the backup was initiated

A checksum is placed in each configuration text file to prevent accidental errors in the Barracuda Message Archiver configuration information. Any changes made to the file will cause the existing checksum to be incorrect, which prevents upload of the modified configuration file. Customers who want to manually edit a configuration file should contact Barracuda Networks Technical Support for the proper procedure.

Automated Configuration Backups

The settings in the Automated Configuration Backups section allow you to select the components you want to back up, specify the backup schedule, and determine how many backups to keep on the remote server.

To automatically generate backups, configure a location on a remote server where the backups are to be kept, and determine which backups should happen when. Each backup type is saved individually, even if they are scheduled to be created at the same date and time.

  • Server Type – The type of server used to store the backup files. Options are FTP andSMB (Windows Shared). Set to Off to temporarily disable automated backups without losing any configured data.
  • Server Name/IP – The hostname (FQDN) or IP address of the backup server.

    If you have selected SMB above and are using a Windows 2003 server, you must use the Windows netbios name and not an IP address in this field.

  • Port – The port used to connect to the backup server. If left blank, the port number most commonly associated with the selected server type is used.
  • Username – The username used to connect to the backup server. Generally a single, lowercase word with no symbols.
  • Password – The password used with the username above. On save, this always displays as 14 filled circles, no matter the length of the actual password.
  • Folder/Path – The full path to the folder or share that is to be mounted by the backup process. This is required in all cases.
  • Backup Schedule – When to perform the backup. Changes to the backup schedule take effect after midnight, so even a modification made at 09:23 for a 15:00 backup does not kick in until the following day at 15:00.
  • Backups to Keep – The number of backups to retain on the backup server. Older backups are automatically purged.

Click Test Backup Server to verify connectivity to your backup server once your access information is entered. Results display in a new browser window.
