Best practive for backup Centos VM on Hyper-V

[pawell]

Hello. There is some virtual machines with Centos 6.5 that i want to backup using Veeam. VM has MySQL, Posftix, Apache running. Hyper-V integration components should be built-in since centos 6.4 according to technet.
Question is how to configure quiescence options to make succesful backup without data loss?

Hello. You can use pre-freeze/post-thaw scripts to make application consistent backups of your CentOS VM. Please look through this existing topic for some script usage examples > Best Practice for Backing Up Linux VMs. Hope this helps!

We have been trying to freeze\thaw MySQL on Ubuntu 14.10 guests using scripts but the scripts never get invoked (as evidenced in the logs).

I found this old post from 2 years ago suggesting calling the Veeam backup job from powershell - not sure if this still applies to Version 8 of Veeam: http://forums.veeam.com/microsoft-hyper ... tml#p78419

I have been working with support but we have not gotten anywhere yet so wondering if the powershell method is our only option or if Veeam 8 should be able to execute .sh scripts on Ubuntu guests now.

Freeze\thaw works fine on Windows guests.

Update:

Found that for Ubuntu, it is required to manually install some daemons even though the integration services are listed as "built-in": https://technet.microsoft.com/en-us/lib ... 31029.aspx

Will see how freeze\thaw runs overnight with these daemons installed and report back.

Unfortunately, the .sh scripts still fail to run - nothing is logged in the job or task logs for invoking the scripts either.

Hi Chris, what's your case ID, so that I could discuss it with the devs internally?

Thanks - sorry for the late reply. Veeam Support ended up providing a hotfix consisting of 2 x .dll files that solved the issue. .sh scripts are being invoked properly.

Compressed hotfix file was named: Fix_42913_

Maybe referencing that hotfix will help others in the near term.
