Linux Hyper-V Guests Backup
One of the main improvements that Microsoft added in Server 2012 R2; was the support and functionality of Linux Hyper-V guests. One of the main friction points for users up to this point was actually backing up Hyper-V guests running Linux.
While it was possible to run Linux within Hyper-V to this point; many didn’t due to these very restrictive limitations.The big one for backup was that Hyper-V had no way to communicate properly through to the Linux OS on the guest as it requires VSS to do so (which is Microsoft proprietary technology). When a backup ran; the Linux machines would be placed into a saved state – which would interrupt it’s ability to serve data and services.
By opening up support for such basic functions as backup – it’s made it more viable for MSP’s and VAR’s to implement various flavors of Linux within Hyper-V environments; when they perhaps wouldn’t have previously.
Hyper-V Integration Services
We’ve written about the Hyper-V Integration Services previously; however it’s worth noting that these are one of the most important parts of any Hyper-V backup. This includes Linux Hyper-V guests back ups as well. Where possible; it’s recommended to have the Hyper-V Integration Services installed on all Linux guest machines to provide access to the additional functionality added.
Microsoft also provide a specific set of Linux Integration Services that can be installed within the majority of common Linux distros as well.
By having these installed; the Linux guest machine will be backed up without interruption – which is the major gripe that most users had.
For best results; use a third party backup application
Linux Hyper-V guests backup has been a major sore point. Luckily; some of the better known players in the backup software space saw this as an opportunity. The likes of Altaro and Veeam have built their businesses around virtualization backup; to the point that they’re the most recognised brands in this area.
This is why it’s always a good idea to fork out a few dollars for a proven solution. In the long run you’ll end up saving time and money by having less monitoring and maintenance to perform.
