Job backup creates unaccessible folders

IllesKokenyesi

Earlier we used RS2019 Jobs function, (and RunJob executable as well) to backup all our robots. (licensed RS2019.5)

Now, if we create a job with a single Backup action, all the controller file folders are unable to open.
Windows explorer error message: 
Location is not available. If the location is on this PC, make sure the devide or drive is connected or the disk is inserted, and then try again. If the location is on the network, make sure you're connected to the network or Internet, then try again. If the location still can't be found, it might have been moved or delete.

None of above is true. (local folders on system disk)

Strange, but if i create a Backup Program Modules action, everything works well, only full backup jobs fails. (tested on more computer of the company, local, or network path, none can access)

Here is our job.xml config file, standard backup action template:

<?xml version="1.0" encoding="utf-8"?>

<JobSpecification>

  <Filter></Filter>

  <SubFilter></SubFilter>

  <Actions>

    <Action id="IRC5.Backup">

      <Parameters>

        <Parameter name="BackupRootPath" value="c:\ABB\{Date}_{Time}" />

        <Parameter name="BackupName" value="{ControllerName}_{Date}" />

        <Parameter name="Overwrite" value="True" />

      </Parameters>

    </Action>

  </Actions>

  <Devices path="c:\ABB\backup.xlsx" filter="(All)" />

</JobSpecification>
