Volume shadow copy service running at backup start causing error Code:0x80042316

[robns]

I'm often getting backup failures with VSS related errors when running Veeam backups at night, 'VSS_E_SNAPSHOT_SET_IN_PROGRESS. Code:0x80042316'. The reason is that the Volume Shadow Copy service is already running when backups start. Something is using it. This service is set to manual in Services.msc and only runs when it is required, but whatever is using it is not stopping it when finished.

At this stage, I'm having to run a scheduled task with 'net stop vss' just before backup on the problem servers, but this should not be required. How else can I diagnose or identify what is causing it to run, what's using it, why it's not turning off.

Thanks.
