Better backups for branches
Asigra adds agentless CDP to backup and recovery solution.
Asigra has announced a major revision of its Televaulting backup and recovery software designed to provide continuous data protection (CDP) to branch offices over WAN links.
Version 6.2 adds agentless backup and recovery technology that optimises the volume of data being stored by removing duplicate content, and adjusts the speed of the backup to available WAN bandwidth, said Asigra. The vendor has followed rivals Avamar and Symantec in adopting an agentless approach for a data deduplication system.
The CDP client can be installed on Windows, Unix and Linux platforms, and is aimed at Microsoft Exchange. It continuously monitors the data to be backed up and automatically replicates block-level changes offsite when they are detected. On the downside, the CDP client creates more data that must be stored offsite, causing storage requirements to swell.
“A customer might have a lot of data that is changing rapidly, but the DSL connection to the datacentre might not be big enough to move all of that data offsite,” said Asigra’s Eran Farajun. “Our CDP software recognises that there is a bottleneck and adjusts the pace at which it collects data so it can do so effectively and efficiently with the WAN infrastructure it has to work with. We get to the lowest RPO [Recovery Point Objective] you possibly can with the WAN infrastructure you have in place.”
