Hyper-V VM backup temp location

Question

Hi all ,

We have a hyper-v cluster and we`re backing up vms with snapshot.

Where are the snapshots temporary folder when the backup is running ?

We have the following errors on the host event viewer and the backup is failing :

There was insufficient disk space on volume to grow the shadow copy storage for shadow copies of . As a result of this failure all shadow copies of volume are at risk of being deleted.

The shadow copies of volume were aborted because the shadow copy storage failed to grow.

Cluster Shared Volume '' ('CSV-Vol06-SSD-Noriel') has entered a paused state because of '(c000000e)'. All I/O will temporarily be queued until a path to the volume is reestablished.

Thanks !

All snapshots are VSS and stored under 'System Volume Information' folder on the Volume which is a Super Hidden folder. In order to view it you will need to uncheck 'hide protected system files' under Folder options.

Hello,

Any idea how to force removing those snapshots under CSV/system volume information folder ?

Here we are facing the following issue:

- NMM9.0.1 backup failed due to insufficent disk space.

- After that try we rezised the disk with additional space (LUN expansion from VNX)

- Retried backup => Fail

- We discovered that disk space is growing

- Stopped Networker services, check for checkpoints => no checkpoints found (Get-VMSnapshot -VMName * -ComputerName $node returns no snaps...)

- We found that under "CSV/system volume infromation folder" there was "orphaned snapshots" created when the backup sessions were tried. But we can't delete those snaps (access denied error)

Any suggestion please?
