DB Backup stopped

[vedadramovic]

Hello,

I have a problem with my DB backup. In many servers on distributed project it stopped working. Automatic backup is set every day at 6 am. In Backup Panel, it gives a status: "WCCOAtoolMedia stopped unexpected". On media there is still a lot of free space.

Here is a log:

Hello,

when looking at the log-messsage you can see that it takes about one hour and the backup is not finished then. Maybe too much data needs to be copied and therefore it lasts to long. Normally a backup shall be finished in a short period of time. As long as the backup is running the functionality is restricted and the system is buffering data.
Please check the settings for the online backup (time range, devivce) and the read/write performance for the used devices (project directory, backup device).

Hello,

When i manually start DB backup, it takes just a minute to stop it and gives a message "WCCOAtoolMedia stopped unexpected" and info says "Not possible to initialize data media" and error code is (-4). It looks like that the problem is in the line that says:

Could not open output file from WCCOAtoolMedia

In configuration of Backup Panel I set last parameters 0, 58 and 0 respectively.

I hope these informations will give you better review in my problem.

Thanks.
