Acronis Backup & Recovery shows the "Failed to create the backup plan" error message when trying to back up to\restore from a subfolder on a network share

This article applies to:

  • Acronis Backup & Recovery 11


  1. You create a backup plan or attempt to recover a backup;.
  2. On the Archive step, you select as a backup location via the tree view pane a network share that has subfolders, the names of which have capital letters:

  3. The execution of the backup task fails with the following error messages in the Acronis Management Console:

    When creating a backup plan:

    Failed to create the backup plan

    Failed to create the archive

    Failed to save the archive metainfo. You either do not have write access to the folder or it is unvailable at the moment.

    When restoring an archive:

    Cannot find the specified archive.


You have selected the network subfolder via the tree view pane. In this case, Acronis Backup & Recovery 11 converts all upper case letters in the name of a parent network folder into lower case.

On the screenshot below, compare the letter case of folders in the folder tree pane and in the Path field. The name of the parent folder Folder in the folder tree pane starts with a capital letter; however, the same folder name in the Path field starts with a lowercase letter.


(!) This has been fixed. The fix is available in the latest released build of the product. See Installation of the latest update of an Acronis product.

To work around the issue without installing the latest build, on the Archive step in the Create backup plan or Recover wizards, select the network backup location in the tree view pane and correct the case of the characters manually in the Path field. Alternatively, type in the full path to the network backup location paying attention to the letter case.
