Setting Up Watched Files
Understanding Source-Based Deduplication
Barracuda's source deduplication method deduplicates local data on the client-side, removing redundancies from the data before transmission,
and then sends that data to the Barracuda Backup Server in deduplicated form, minimizing LAN bandwidth and data sent to the local server.
Source deduplication is implemented through the . During Agent installation, a small database is created on the server toBarracuda Backup Agent
keep track of data chunks so only unique data is compressed and sent to the Barracuda Backup appliance for processing, reducing network traffic
and the backup window, as shown in Figure 1.
Figure 1. Source Deduplication.
For VMware backups, Barracuda leverages VMware’s vStorage APIs for Data Protection (VADP) to back up virtual disks, utilizing Changed Block
Tracking (CBT) to send only unique chunks to the Barracuda Backup Server, as shown in Figure 2.

The seldomly used Watched Files
feature has been deprecated in
firmware versions 5.2, and will not
be supported for new Barracuda
Backup Servers. Note that existing
Watched File Rules will continue to
function as expected.
