How to Back Up Archives

Step 2. Set Up Raw Email Data and Metadata Snapshot Backup

1. Log into your Windows Network or Backup System such as Barracuda Backup.
2. Connect to the Barracuda Message Archiver data partition by accessing \\ host \BMA-SMB-#.
3. Back up the following files and directories:
   • Raw Email data:
     
     • *.zip (1GB-sized message archives)
     • <nnn>/ (directory containing recently received emails, not yet merged into a . zip)

   • Snapshots of Metadata

     The following snapshots are performed nightly. In the event that data restoration is necessary, typically only the raw emails (from .zip files) arrived in the last day must be reprocessed.

     • FolderSync (snapshot of foldersync data) 
     • index (snapshot of archives of index metadata)
     • index_backup (snapshot of the entire index)
     • ldap_cache (snapshot of ldap group information)
     • log (snapshot of important system information)
     • postgres_backup (snapshot of system databases)

1. Log into the Barracuda Message Archiver as the administrator, and go to the Advanced > Storage Manager page.

   1. In the Default (Group) table, select the share from the drop-down menu.
   2. Click Add Mirror.
3. If you do not have a CIFS/Windows share already set up, complete the following steps:

   2. In the Group table, select the share you want to use to back up the data from in the drop-down menu, and click Add Mirror.

Barracuda Cloud Storage may only be used to mirror the data that is stored on the Barracuda Message Archiver to Barracuda Cloud Storage for off-site redundancy. Retention policies that you set on the Message Archiver appliance will be the same in Cloud Storage. Once you link your Barracuda Message Archiver to a Barracuda Cloud Control account, you can mirror all new and existing mail and then search, export, or forward that mail from both the Barracuda Message Archiver web interface and from Barracuda Cloud Control. Select Mirror in the Cloud Storage section on the Advanced > Cloud Storage page in the web interface.

Use the following steps to set up mirroring to the Barracuda Cloud:

1. Log into the Barracuda Message Archiver as the administrator, and go to Advanced > Cloud Storage.

2. Click Connect to Cloud Storage; the Login page displays.
3. Enter your Barracuda Cloud Control account credentials, and click Sign In.
4. In the Location page, enter the City, State, and Country where your mail server is hosted; your account can only link to one location. The first Barracuda Message Archiver appliance you link to determines the data center that all appliances on your account will use. For example, if you select Canada as your country, your appliances will use the data center in Canada.
5. Click Next. In the View Summary page, click Activate to link your Barracuda Message Archiver to the Barracuda Cloud Control account.
6. The Advanced > Cloud Storage page refreshes and displays the Cloud Storage options. Select Mirror; read the warning, and click Confirm to continue.
7. In the Rate Control section, specify the data replication rate to Barracuda Cloud Storage.

As messages are sent to Cloud Storage, related statistics display on the BASIC > Dashboard page.
