This is an issue with SELinux 3.7.19 and higher

This article applies to:

  • Acronis Backup & Recovery 10 Advanced Server
  • Acronis Backup & Recovery 10 Advanced Server Virtual Edition
  • Acronis Backup & Recovery 10 Server for Linux


  1. You are attempting to mount a backup from Acronis Backup & Recovery 10 GUI;
  2. The attempt fails with the following error message:

    Failed to execute the TrueImageMount command
    'mount: you must specify the filesystem type'

You attempt to restore a backup with Red Hat Enterprise Linux 4.6 x64 into an Red Hat Enterprise Virtualization virtual machine. After restore succeeds, the vm does boot into an kernel panic.


Backups fail with error messages stating that the SnapAPI module is not loaded for the running kernel.

In dmesg/messages, you can find these errors from SnapAPI: "make_request_fn is NULL." 


Backup agents BEFORE C21.09 release had a version of the SnapAPI kernel module (versions up to 0.7.140) that could not compile successfully on kernels 4.18.0-315 or higher (in the 4.18. series).
