Symantec BackupExec

Accelerate Symantec BackupExec over the WAN

Symantec BackupExec is a small-medium business solution for backing up local or remote data to virtually any storage device including tape, disk and cloud. BackupExec users can restore data from files, application objects, applications, VMs, and servers directly from backup storage.

To ensure disaster recovery, many organizations maintain backup facilities in locations geographically distant from their main data centers. Any backup solution sending large volumes of data over longer distances can run into limitations in the wide area network. When the WAN has limited bandwidth, packet loss, out-of-order packets, or high latency, backup jobs can fail or exceed desired timelines.

How Silver Peak can help

Silver Peak Replication Acceleration software fixes the problems that exist on the WAN, enabling more data to be backed up, in less time, and over longer distances. Silver Peak software solves WAN problems by repairing dropped and out-of-order packets, overcoming the effects of round trip time (RTT) latency, and providing real-time deduplication and compression of all data sent across the WAN. Silver Peak also provides an IPsec AES-256 site-to-site VPN that secures backup traffic without impacting performance.

  • Improve data transfer times. Silver Peak’s Network Acceleration overcomes the effects of round trip time (RTT) latency. 
  • Maximize network efficiency. Silver Peak’s Network Memory recognizes repetitive information and delivers it locally, a concept known as data reduction. Network Memory can reduce as much as 99% of WAN traffic by eliminating the transfer of duplicate information. Advanced compression techniques further reduce the amount of WAN bandwidth required for backup and replication. See the customer results below for an example.
  • Reduce packet loss and delivery errors. Silver Peak reduces the impact of both packet loss and jitter that occurs when router links are oversubscribed, causing dropped or re-ordered packets.

Once deployed, Silver Peak software is easy to monitor and manage. Reports are in storage-friendly terms showing the data throughput across the WAN in bytes. Storage traffic is segmented by application, such as replication and or backup. Reporting includes minute, hour, and daily intervals, and includes a 10 day chart to reflect performance data before and after any changes made during the weekend. When the problems on the WAN have been repaired, it is easy to meet, maintain, and even reduce Symantec BackupExec times.
