    • To back up network file shares, turn on Enable File Share Backups, and enter your credentials.

 Authentication and System Configuration Notes

  • Backups for Mac OS X/Linux/UNIX (SSH Connections)
    Barracuda Backup uses an SSH (Secure Shell) client to access data contained on Mac OS X or Linux / Unix based computers running an SSH daemon. The SSH client uses public key cryptography to establish a secure connection to the SSH daemon.
    You must configure SSH access to any Mac OS X or Linux / UNIX computer you want to back up. Follow the on-screen instructions on the Backup > Sources > Add Computer page according to the operating system.
  • Directory-Based File Shares
    When you back up a file share you must specify the share name on the network before you can select the folders to be backed up. On a Windows machine, a share name can be a drive volume such as "C$", or a folder and its associated subfolders such as "My Documents". At a minimum you will need Read access to the data that you are backing up and Change Access or Full Control to the shares in order to perform a restore. For Mac OS X and Linux / Unix-based computers with SSH connections, the share name should be the entire path to the directory you would like to back up, e.g., /home/<user>.
    When you select folders for backup you should begin by selecting the folders at the top of the folder tree hierarchy, and then deselect folders lower in the hierarchy that you do not want to back up. You can also specify an optional exclusion rule, which is applied when the backup runs to rule out files that do not meet your back up criteria.
  • Message-Level Backup: Microsoft Exchange and Novell GroupWise
    When you select the Message-Level Backup data type, you must supply the authentication information to access your mail server before you can select which mailboxes to back up. In addition to the authentication information provided on the Barracuda Backup web interface, you must configure the Message-Level settings on your Exchange or GroupWise server.
    For Microsoft Exchange servers, refer to Exchange Message-Level Backups for detailed instructions for configuring message-level backups.
    For GroupWise, refer to GroupWise Message-Level Backups for detailed instructions for configuring message-level backups.

Supported Data Types
For additional information, refer to the Supported Data Types section.

Backup Schedules

Once you configure computers and data sources, create granular backup schedules. Select specific sets of data to back up and configure multiple schedules for each source, each with different sets of data selected. See the Schedules Page for more information.

To create a backup schedule:

Go to the Backup > Schedules page of the Barracuda Backup web interface. Click Add a Schedule and fill in the information on the Add Backup Schedule page:

  • Schedule Name – Enter a label to identify the backup schedule.
  • Items to Back Up – Turn Apply to All Computers and Data Sources for this Barracuda Backup Appliance on to back up all content, or turn off, then expand and select the items you want to back up.
  • Schedule Timeline – Turn on the days you want the back up to run.
  • Daily Backup Timeline – Enter the start time; turn on Repeat if you want to specify a time period and end date to repeat the backup.

If the backup schedule is for Microsoft SQL or Microsoft Exchange, you must specify the type of backup to run:

  • Complete – This backup type performs a full backup of data, including the transaction logs.
  • Log – This backup type only backs up transaction logs created since the last full backup.
  • Smart – This backup type is a combination of the full backup and the transaction log backup, minimizing the impact of backups on network resources necessary to transfer data offsite. Barracuda Networks recommends this backup type for SQL and Exchange servers.

With the Smart Backup type, threshold values are used to determine when to switch between full and log backups. The minimum threshold value specifies how many days Barracuda Backup continues to back up transaction logs before another full backup is run. After the minimum threshold value is met, Barracuda Backup determines whether to perform another backup based on the binary data queue. If the binary data queue size exceeds 1 GB, Barracuda Backup continues the transaction log backup until:

  • the maximum threshold level is met, or
  • the queue size drops below 1 GB

Set the Backup Rate Limit (Optional)

Rate limits control the data replication rate to Barracuda Cloud Storage or other offsite storage locations. You can limit Internet bandwidth consumption during peak usage times, and schedule backups for non-peak hours.

Your initial offsite backup may take on the order of days to complete but all of the data is backed up locally on the Barracuda Backup appliance during this period. After the initial large transfer is complete, replicating your data offsite should complete with only a few hours of transfer each day. By default, Barracuda Backup is configured to run full speed data transfers at night so that bandwidth is not affected while most people are at work. An alternate rate limit allows you to adjust the limit speed and time interval.

The length of transfer time it will take to get your data offsite is impacted by the compression and deduplication rates on your data, the uplink speed of your Internet connection, the amount of data that changes every day, and any speed limits you apply to Barracuda Backup.

To set the backup rate limit:

  1. Go to the Backup > Replication page, and click Add a Target.
  2. In the Add Replication Target, enter the Replication Target Information.
  3. In the Rate Limit section, the following options are available:

    OptionSettingsDetails
    Default Rate Limit
    • Full Speed – Uses 100% of available bandwidth
    • Kb/s or Mb/s – Specify the rate limit in Kilobits or Megabits per second
    Specify the default rate limit.
    Alternate Rate Limit
    • Full Speed – Uses 100% of available bandwidth
    • Kb/s or Mb/s – Specify the rate limit in Kilobits or Megabits per second

    You can optionally create an alternate rate limit which is maintained only during the specified time periods:

    • From/To – Specify the start and end time (24 hour format)
    • On – Select the days on which the alternate rate limit applies
  4. Click Save.

 

Exclude Files from a Backup (Optional)

You can create exclusion rules that use pattern matching to identify directory or file names that are not to be backed up. Files which are typically excluded from backups include temporary files, music, movies and other files which are not essential for business needs.

Use the following steps to create an exclusion rule:

  1. Go to the Backup > Exclusions page of the Barracuda Backup web interface. Click Add an Exclusion.
  2. Fill in the information on the Add an Exclusion page:
    • Exclusion Rule Name – Enter a descriptive label to identify the exclusion rule.
    • Add Exclusions to Reports – Turn on to include exclusions in reports, and turn off if you do not want to include exclusions in the reports.
    • Apply Recursively to Sub Directories – Specify whether to apply the exclusion rule recursively to sub directories.
    • Where to Exclude – Turn Apply to All Computers and Data Sources for this Barracuda Backup Appliance on to apply the exclusion rule to all computers and data sources for the selected Barracuda Backup appliance, or turn off, then expand and select the items to which to apply the exclusion rule.
  3. In the What to Exclude section, specify what to exclude:
    • From the Preset Expressions menu, select the content you want to exclude, for example, Video files, then click Add.
    • In the Expressions field, enter a search string to exclude, for example, *.mp3, then click Add.
  4. Click Save at the top of the page to add the exclusion rule. 

To edit an existing exclusion rule, go to the Backup > Exclusions page of the Barracuda Backup web interface, and click Edit following the exclusion rule you want to edit. Make the necessary changes, then click Save.

To delete an exclusion rule, go to the Backup > Exclusions page of the Barracuda Backup web interface, and click the Remove following the exclusion rule you want to remove. Click OK to remove the rule.

Create Data Retention Policies

Data is retained based on a traditional grandfather-father-son (daily-weekly-monthly) rotation model. You can specify how long to keep daily, weekly, monthly, and yearly backups by creating data retention policies. Different retention policies can be created for different sets of data including files, data backed up by the Barracuda Backup Agent (Exchange, SQL, System State), and email messages.

You can create one policy for all of the computers and data sources on a Barracuda Backup appliance or multiple policies that each include some subset of the data.

To set retention policies:

  1. Go to Backup > Retention Policies, click Add a Retention Policy, and enter a name to identify the policy.
  2. In the Items to Retain section, specify the data sources to which the retention policy applies; the Retention Timeline section displays. Select a timeline template on which to base your retention policy, or specify your own revision timeline.
  3. If applicable, specify the Email Message Timeline.
  4. Click Save.

When data is removed according to a retention policy, it is deleted from both the local Barracuda Backup appliance and the offsite storage locations. Removed files that have been backed up using Network File Shares Protocol or SSHFS may be retained for a longer period of time, according to the configuration. Otherwise, once your data has been purged, it is gone forever. Purging applies to historic file revisions only; your current data is not impacted by a retention policy.

Your initial backup takes some time to complete; you can view backup status in the Reports > Backup page.

Replicate Data to another Barracuda Backup

Before configuring a backup destination, verify the following:

  1. Make sure that your retention policies are configured before configuring replication. Otherwise you may waste bandwidth copying data that does not need to be replicated.
  2. Verify Internet connectivity between the local and remote Barracuda Backup appliance(s). Configuring a secure VPN connection between multiple Barracuda Backup appliances ensures the highest level of security possible.
  3. You must have the serial number and replication code of the destination Barracuda Backup appliance. Go to the destination Barracuda Backup appliance, and go to the Backup > Replication page. The serial number and replication code display at the top right of the page.

Important

  • Only the Barracuda Backup appliance 490 and higher can act as a backup to other Barracuda Backup appliances, although any Barracuda Backup appliance can send data.
  • Data can be backed up to both a second Barracuda Backup appliance and to Barracuda Cloud Storage. Data that is backed up on a second Barracuda Backup appliance cannot be backed up yet again onto another Barracuda Backup appliance.
  • For every Terabyte of data replicated, Barracuda Networks recommends a 1.5 Mbps or T1 connection.
  • You must have the serial number and replication code of the destination. These can be found by selecting the destination Barracuda Backup appliance and looking at its Backup > Replication page.

Barracuda Backup appliances used to back up data from one or more Barracuda Backup appliances are known as destinations. Data from one Barracuda Backup appliance can be replicated to one or more destinations.

To configure data replication,

  1. Log in and select the Barracuda Backup appliance to which you want to add a replication destination, and go to the Backup > Replication page.
  2. Click Add a Target.

  3. In the Add Replication Target page, enter the target Barracuda Backup details in the Replication Target Information section, or select an appliance on your account from the drop-down menu to automatically populate this section.
  4. In the Rate Limit section, select the Default Rate Limit; by default, Barracuda Backup uses Full Speed as the default rate limit.
  5. Optionally, you can enable an Alternate Rate Limit.
  6. Click Save.

Once a target is added, it appears in the Sending Data To table. If the status displays as online and reporting successfully (status_success.png), the two systems are able to communicate.

You can select to replicate all data to a target appliance or to Barracuda Cloud Storage. If you want to send data from diverse sources to both of these options, do not select Replicate all data to this target. Instead, edit each data source on the Backup > Sources page, and specify where its data is to be replicated.

This option is not available in Local Control.

Edit Replication Settings
  1. Log in and go to the Backup > Replication page.
  2. Click the Settings (SettingsIcon16x16.png) icon in the Target List section.
  3. In the Replication Target Information section, you can modify the destination IP address, disable data replication, modify rate limits, and specify whether to send all data on the Barracuda Backup appliance to this target.
Remove a Barracuda Backup Appliance

To permanently remove a replication destination, click Remove in the Target List.

Disable Replication

Pausing replication causes data from the appliance to be queued for 24 hours; data replication automatically resumes after 24 hours. To temporarily disable replication, clear the Enable data replication setting on the Backup > Replication page.
