5877: Acronis Backup & Recovery: Impossible to Back Up Both Local and Network Folders in One Task

Create two separate tasks if you are planning to back up local and network folders

This article applies to:


  1. You create one task to back up both local and network folders:

    On the Data to Back Up screen you select a local folder:

    Then you select a network folder:

  2. The operation fails with the following error message:

  3. The operation log will have an error similar to the following one:

    Task 'Simple backup task' failed: 'File I/O error.|Additional info: |--------------------|Error code: 7|Module: 4|LineInfo: f35f747b3b21faa9|Fields: function : WNetGetUniversalNameW, filename : C:, $module : C:\Program Files\Acronis\BackupAndRecovery\mms.exe|Message: File I/O error.|--------------------|Error code: 65520|Module: 0|LineInfo: bd28fdbd64edb8b9|Fields: code : 2147944650|Message: This network connection does not exist|--------------------'." code="11,863,304(0xB50508)" module="181" Owner="Acronis Agent User"

  4. An attempt to edit the backup task will fail with Acronis Backup & Recovery 10 asking for credentials:

    The product will not accept any credentials.


This is a limitation of the product. One task cannot have different access credentials.


As a workaround, create separate tasks to back up data from different sources.
