The main backup purpose is to protect your data against disasters and VM failures. Having only one copy of a backup file does not provide the necessary level of safety. To build a successful data protection and disaster recovery plan, you must have at least one independent copy of a backup file offsite, for example, in the remote site. To optimize data transfer between remote sites over the WAN, Veeam Backup & Replication offers the WAN acceleration technology.
To learn more about the 3-2-1 backup strategy and WAN acceleration, see this Veeam Blog article.
This report analyzes amount of traffic transmitted to target repository by backup copy jobs, evaluates the efficiency of backup data transfer through WAN accelerators and estimates the amount of network traffic savings.
The report output includes three charts and provides details on traffic usage:
- The Traffic Efficiency (GB) chart shows the actual amount of traffic read from the source datastore and the amount of traffic transmitted over the network to the target repository.
- The Traffic Savings by Day (GB) chart shows the amount of traffic saved on each day of the reporting interval (that is, the difference between the amount of read traffic and the amount of transferred traffic).
- The Savings Ratio by Day chart shows daily fluctuations in the raw data to traffic savings ratio.
- The Accelerators Details table provides details for each pair of WAN accelerators used by backup copy jobs: number of restore points transferred, amount of data read from the source repository, actual amount of data transferred to the target repository and amount of saved traffic.

- The Job Details table provides detailed information on job sessions, restore points transferred by the pair of WAN accelerators, original backup file sizes, actual amount of data transferred, amount of saved traffic and savings ratio.
WAN accelerators allow reducing the amount of network traffic transmitted to remote DR sites by leveraging the deduplication techniques.
This report helps you analyze traffic savings and raise the efficiency of your backup copy jobs.
You can specify the following report parameters:
- Scope: defines a list of Veeam Backup & Replication servers to include in the report.
- Accelerators: defines pairs of source-to-target WAN accelerators to include in the report.
- Backup Copy Jobs: defines a list of backup copy jobs to include in the report.
- Interval/Start Date – End Date: defines the time period to analyze in the report.
