We are having issues with these. Sometimes they work and sometimes they don't. When they fail, we get Task Exception Errors like these:
- Exception in Task: Object reference not set to an instance of an object.
- The given key was not present in the dictionary.
- Value cannot be null.
We actually run two backup jobs - the default one and one that backs up the settings to a network share. The network share job almost never fails, only the local job.
However, in the last 2 days, 2 different machines have gotten "stuck" in the Running status (both jobs, local and network share) and would not stop until I restarted the VisualCron service.
The real problem is when they get stuck, they are using a TON of resources (25% CPU and hammering the disk drives.) One of these occurrences were on a production web server. I'm not sure what to do to troubleshoot the issue.
