Our latest survey finds that more companies are relying on automated processes to back up their remote offices, and more backup data is making it back to the main data center than ever before.
Three years ago, nearly 25% of the firms we polled entrusted data backup at their remote sites to non-IT staff members. That number has now plummeted to only 6%. At the same time, the number of companies using automated processes to back up remote offices grew from 33% to 46%, so it looks like many firms are no longer relying on “civilian” backup jockeys. And two-thirds report that backup data is shipped to the main data center from an average of 28 remote locations. Thirty percent back up directly to disk at remote sites and then replicate to the data center, while 25% dedupe backup data first and then replicate. Thirty percent of firms looking to centralize their backup are considering a WAN optimization device and 29% expect to add a dedupe appliance that can replicate to the data center. The biggest gripe about remote site backups is throughput and packet loss issues when sending data over the WAN.
“I think the biggest problem with cloud backup is that the bandwidth required for efficient backup is never available.” --Survey respondent
