48      Barracuda Backup Service Administrator’s Guide

The 

 page provides an overview of the performance and health of your Barracuda Backup. If 

you have more than one Barracuda Backup Server linked to your account, you can select a specific 
server and view its individual statistics. 

From the 

 page you can view:

• Backup activity for local and offsite locations, indicating the size and the number of 

backup files added by date.

• Storage statistics representing the total amount of storage used by each data source type 

on the local Barracuda Backup Server and at Barracuda Cloud Starage as well as the 
number of files and messages backed up. If this system is replicating data to or from 
another Barracuda Backup Server, then those storage statistics appear on the 

page on both Barracuda Backup Servers.

• Efficiency statistics show:

-  Actual Storage: The amount of actual storage space being used 
-  Snapshot Equivalent: The amount of space that would be required to back up your 

data based on your retention policies projected over the next three years, without 
deduplication and compression 

-  Deduplication Ratio: The overall amount of space savings with deduplication and 

compression compared to the snapshot equivalent. See Deduplication for Backup 
Efficiency, page 6, for details about how deduplication works. 

• Status indicators for the health of the Barracuda Backup Servers, local and offsite 

backups, and data sources. Green shows that your servers are online and that no errors 
have been encountered as a result of your backup. Red indicators are displayed when a 
local server is offline or when errors were generated during a backup. Mouse over the 
indicators to see more details.

• Performance statistics for the Barracuda Backup Servers, including percentage of CPU, 

disk and Ethernet usage. Performance statistics displayed in red signify that the value 
exceeds the normal threshold. These values will fluctuate based on the amount of data 
that is being backed up, but if any setting remains consistently red for a long period of 
time, contact Barracuda Networks Technical Support. 

• Storage History (if one Barracuda Backup Server is selected) displays the current, 

historic and actual data storage size on the local and cloud locations by date.

• Transfer History (if one Barracuda Backup Server is selected)  displays the efficiency of 

your data transfer and the size of the file parts yet to be transferred offsite, organized by 
date.

To check that a Barracuda Backup Server is operating correctly, select it from the list of Barracuda 
Backup Servers and navigate to its 

 page. 

You can look at the Transfer History and see the amount of bytes remaining to be transferred. If there 
is a large amount of data there (80 GB or more), there are a number of things to check, all under the 

 tab:

• Adjust the rate limit.
• Check the amount of data being backed up nightly to ensure the Barracuda Backup 

Server is doing transaction log backups for Exchange and SQL.
