3-EVEN ID 7001:

VssAdmin: Unable to create a shadow copy: Another shadow-copy creation is in progress, so the current shadow copy cannot be created.  There are a number of common scenarios causing this problem:          * If Shadow Copies of Shared Folders is set up, ensure that no two volumes have schedules that lie within five minutes             of each other.           * If automatic backup of any form is scheduled, ensure that the backup schedule does not overlap with the schedule            used for Shadow Copies of Shared Folders.    Generally, retrying the operation after a few minutes or changing the schedule of an automatic task should fix this problem.
Command-line: 'C:\Windows\system32\vssadmin.exe Create Shadow /AutoRetry=15 /For=\\?\Volume{11ced9fd-88b8-4438-aef9-785a0a4f46c7}\'.
