![]() Business continuity has never been as easy or as reliable. While virtualized, backup clients can continue a normal backup schedule. Network resources can also be configured dynamically, allowing for changes to be made without restarting the virtual machine. When virtualizing a recovery point, Datto’s advanced web interface allows for the configuration of CPU and memory resources. Regardless of whether the recovery point is months or even years old, Datto’s DRaaS solutions end the long RTOs caused by reconstructing backups on disk or restoring from magnetic tape. How to Back Up a Virtual Machine with a SIRISĭatto Instant Virtualization allows a protected system to be virtualized and hosted either locally on a Datto BCDR appliance (SIRIS), or remotely in the secure Datto Cloud (Datto SIRIS and Datto ALTO) in seconds. Depending on the backup software vendor’s pricing model, agentless backups can be less expensive as well, since users don’t need to pay licensing fees on a per-agent basis. Agentless backup doesn’t require users to install agents on protected servers, preventing potential data loss. Therefore, you don't have to use IOPS on the local VM or use network bandwidth that would be better used for actual production processes. ![]() You get more benefits using agentless backups with a virtual storage location that understands how to transmit data from the hypervisor to the data store without using networking traffic. A good agentless backup software uses the Change Block Tracking (CBT) that exists with the Hypervisor. Where agentless backup procedures really shine is VM infrastructure. However, there is a chance that temporarily injected modules can create data integrity issues on protected machines. For the most part, this isn’t an issue, especially if the application is backed up offers an API for the backup software to interface with. Many agentless backup products, for physical production machines, must inject temporary executable modules into systems before the backup can occur. This is particularly important in virtual environments with many production machines, VMs can be spun up so easily it’s common for them to go unprotected when using agent-based backup because a backup agent is never installed.
