Re: The clients are auto restarting backup after concluded. How can I fix it?

The mminfo/save set report only show the result - it will not tell you why the group is restarted.

Looking at the save sets' timestamps from your first screenshot, could it be that the interval for the group has been changed from the default (24hrs) to only 4hrs ... and that the group is just started again right after it has finished?

Look at the group's properties ... and at the backups' duration.

In fact NW 8 could help here because you can easily select earlier savegroup completion reports to compare the values.
