VAW source disk space warning query

[gosnells]

Hi,

I have Veeam Agent for Windows setup to backup a machine.
One drive is dedicated to the pagefile, with 1.36GB free, or ~3.36% free.
Veeam Agent backups up ok, but the backup job email notification includes a warning: Disk pagefile (I:) is running low on free space"

I've done a search but only found references to BackupRepositoryFreeSpaceThresholdPercent (destination) and DisableVolumeFreeSpaceCheckWarning (all source drives) registry tweaks.

Is there a valid VolumeFreeSpaceThresholdPercent or similar regkey to tune this free space setting ?
Is there some other way to tune either the free space threshold or free space warning check on a PER drive basis ?
What would be the default percentage of space available threshold that triggers the disk space email job notification warning?
(this VAW instance is not linked to a B&R repo)

many thanks in advance.

edits: for clarification
Windows Server 2016 system

issue only observed on system running VAW 3.0.1.1039
A similarly configured system (with same sized pagefile on same sized drive) running VAW 2.2.0.589 doesn't give the same backup job disk space low warnings.

Hello,
nope, nothing for drives. The DisableVolumeFreeSpaceCheckWarning is the only one to get rid of the message if you cannot free up space.

About VAW2: might be an issue that was fixed with VAW3

Best regards,
