 OK　I think you have same snapshot patterns for different snapshots schedule. Change the Naming Pattern for Generated Snapshot as follows to each policy.  Snap1      Snap1_%Y-%m-%d-_%H-%M Snap2      Snap2_%Y-%m-%d-_%H-%M Snap3      Snap3_%Y-%m-%d-_%H-%M  By default "ScheduleName_duration" parts wouldn't change even if you modified the policy name.You have to modify it by yourself.
Hi,   when we try to create a manual snapshot its working just fine. but scheduled snapshot is failing with below error.  at 10PM schedule time we have only one other  share snapshot schedules so basically we have 2 shares snapshot schedules at same time , is this a problem ?   i look up in admin guides couldn't find any of this issue.
Snapshot failure - Multi-schedule collision
