Retry or cancel
This problem started for a quite a while time ago.
While running back up plan any task could run into situation when it fails to lock the file.
In this case Acronis engine comes up with the message box "Failed to lock the file, please Retry or Cancel", and waits(!!!!!!) for response, and if I do no check it on the daily or even hourly basis it hangs and get all backup plans followed by this failed task postponed, possibly for any time till I check it manually (!).
The question is what kind of back up server is it, if it does not time out own message boxes and going ahead by itself? Server must have the watchdog and know how many backup plans is scheduled, scan hanging tasks and exactly in the way operating system scheduler does it.
Is there any way to set these boxes to get timed out? I was out for some business, came back and found office was not backed up for two weeks now.
