Causa
The problem arises when you are protecting a machine which does not have an actual SQL role and/or instance running in it, but has the SQL Server VSS writer present and not being used. Rapid Recovery queries the writer, along with all others, when it's time for a backup which may be in a failed or waiting for response state and Rapid Recovery flags this as a VSS problem. -
Resolução
To resolve this issue, follow these steps:
- Launch the Core GUI
- Navigate and select the affected machine from the column of protected machines to the left
- Enter the Settings tab of the agent
- Under the Transfer section locate the sub-section called Excluded Writers
- From the list of excluded writers locate the one called SqlServerWriter
- Click on the No option to display the option to check a box and make it a Yes
- Click on the check mark to accept the change
- Force a snapshot for the agent
