Collecting Log Information for the ZertoVssAgent
When 
ZertoVssAgent is installed
, adding checkpoints to the journal can be synchronized with Microsoft Volume Shadow Copy Service (VSS) snapshots, as described in 
Ensuring Transaction Consistency in Microsoft Windows Server Environments.
Logs generated by the 
ZertoVssAgent are saved separately and not collected using the
 Zerto Virtual Replication diagnostics tool, described in 
Collecting Zerto Virtual Replication Logs. These logs are small and can be zipped and sent to Zerto support separately.
The logs are saved to a Zerto folder under the program data folder. For example, depending on the Windows operating system, the logs are in via C:\Documents and Settings\All Users\Application Data\Zerto or C:\ProgramData\Zerto.
