Errors in Windows Application event log
Posted: 24 Jan 2021, 05:11
Hi...
Environment:
Windows Server 2008 R2 standard, service pack 1, standalone (no domain)
Cobian Backup Gravity (service mode)
CB Service is running as local system
Two backup tasks, both from one folder on local disk to another folder on local disk.
Trigerred by schedule every night, incremental mode, 2 full copies to keep...
Tasks are executed properly, backup is done as expected, but...
Every time any of this two tasks is trigerred by schedule I get following 4 errors in win Application event log.
Checked permisions in com, HKEY_LOCAL_MACHINE>SYSTEM>CurrentControlSet>Services>VSS>VssAccessControl.
Any idea?
