Hello,

VSS snapshot is mounted either to the off-host proxy or is stored on the on-host proxy (Hyper-V host itself). Can you please clarify your issue? Do you see job failures due to lack of the free space on the disk? What disk do you refer to?

Thank you!

We have thinly deduped volume on which VM vhdx exists. So i wonder if snapshot will not consume all free space because it will lead to volume crash if we exceed space limits. Or maybe veeam will not create snapshot if volume free space is not enough?

And also i havent tried to backup VM with veeam. Due to lack of space i have to delete all previous backup done with other software... But when im not sure about veeam backup success i dont wanna do it

Im doing off-host backup.

I have a similar issue with one of our 2012r2 hosts, and we get error/warning of 'low disk space' &
'Skipping VM processing due to insufficient free disk space on drive'
we tried to change checkpoint location to a different disk, but I guess Veeam is using vss and stores the shadow copy with the .vhdx

Do we need to enable/configure Shadow Copies on the disk we pointed the Checkpoints to, which has pleanty of free space?

Hi,

You can set up a desired value for the notification about the free space and choose to skip processing of the VM there.

If it necessary in your case you can do that, we have no such requirement.
Please review this existing discussion about the same issue. Thanks!
