Information Store (3484) Shadow copy instance 1 encountered error -560 on freeze</p> <h3 data-id="cause">Cause</h3> <p>This problem occurs if the Exchange transaction log files are manually moved or are manually deleted from the transaction log folder when a storage group is running. The VSS process tries to delete each unnecessary log file after a full online backup. If the VSS process cannot find one of the log files, the backup fails and the backup in progress flag is not reset.</p> <h3 data-id="resolution">Resolution<a name="_GoBack" id="_GoBack"></a> </h3> <p>To resolve this problem, follow these steps:</p> <ol><li>Take a full Exchange backup. If this action does not resolve issue, proceed to next step.</li> <li>On the affected Exchange server, stop the Microsoft Exchange Information Store service. Alternatively, dismount all the stores that are in the affected storage group.</li> <li>Run the <b>eseutil/mh</b> command against each database in the affected storage group. Do this to make sure that each database is in a Clean Shutdown state.
