Hi all, This is Chaitanya, new member on this forum. I am maintaining a SQL server on which we have about 150 databases which we backup using a maintenance plan. Since a week the plan is failing to backup two databases with the "Operating System error 3". Using "net helpmsg 3" command I found the explanation of the error which says "Path not found". For me this is weird as all the databases are being backed up at same location and only two are failing with this error. All the other are backed up properly. Please find the error log for the maintenance plan as below: I am a bit apprehensive about the bold part of the log. I am failing to find out the issue that may be causing the plan to fail only for two databases. If there were any errors in the plan itself, none of the databases should have been ever backed up. But all the databases were backed up properly but since a week I am having this issue. NOTE: All the databases are backed up in a separate sub folder for each in a directory which has relevant privileges for user which runs SQL Agent.
