Backup Plan Live Update Stopped Working

[redreptionil]

Over much of this month, Backup Plan has been failing to show up in the System Tray (it's set to start at Windows launch). Of course, I rarely notice that until later in the day I realize I've gotten no notification that my scheduled backup has run (or its results). If I check Task Manager, Backup Plan is happily sitting there apparently running. But, its window is nowhere to be found and it's not in the System Tray. If I go to the Start menu and try to run Backup Plan manually, I get the security notification asking if I want to run it, but then nothing. If I end the Backup Plan task in Task Manager and try running it again, I get that same security notification and up pops the program. Even more oddly, according to the line for the scheduled backup, it's been starting and finishing those backups normally and on time. The log confirms that and if I run the scheduled backup manually, it doesn't find anything to back up (again indicating that the scheduled backup is running correctly). If I modify and file somewhere and manually backup, it finds and backs that file up. So, it appears as if Backup Plan is running normally and just doesn't want to tell anyone about it. Also, if I "close" Backup Plan, it correctly minimizes to the System Tray and stays there until I reboot.

Looking in Reliability Monitor, I'm seeing a lot of entries saying Backup Plan's Live Update has Stopped Working:

AFAIK, my software is fully up-to-date:
Windows 10 Pro x64, version 1903, build 18362.295
ASUSTOR Backup Plan version 2.0.2.37100 (if I run check for updates manually in Backup Plan, it completes successfully and says I'm up to date).

I really wish Asustor would do something about this. I'm tired of seeing that Backup Plan failure every single day.

I could be caused by anti-virus software. You can try to disable the software after issue happened (re-run backup plan to see if it stopped suddenly). If it's not the case, I think you should send a support ticket to asustor directly.

The .Net Runtime related Event 1026 I posted has System.String.Copy(System.String) as the topmost problem. Looking that up, I find:

https://docs.microsoft.com/en-us/dotnet ... mework-4.8

which says:

"Important

Starting with .NET Core 3.0, this method is obsolete. However, we do not recommend its use in any .NET implementation. In particular, because of changes in string interning in .NET Core 3.0, in some cases the Copy method will not create a new string but will simply return a reference to an existing interned string."

So, I'm assuming it's bad, obsolete code in LiveUpdate.exe and needs to be updated.
