The system call level is not valid

Thread needs solution

I have problems with backups of shared folders, always an error message "The system call level is not valid" appears me. This started after an upgrade to Acronis Backup Server 11.5 Release 6.

What should I do to correct the problem?

Hello Edoardo,

Thank you for your posting! Do the issue occur only to some specific shares or to all shares? Could you create a new backup plan and check if the issue persists. Please also attach the full log after backup (Log - Save all to file).

Thank you,

I returned to create the backup job but I still get the same error. I'm noticing that this message is replicated in various shared folders.

Does it have to do with the configuration?

Hello Edoardo,

Thank you for additional information! Please specify shares per IP and check suggestions from this article: https://kb.acronis.com/content/2954 Make sure you are specifying credentials in the proper form:

  • NAS.local\user
  • IP_of_server\user
  • Domain.local\user   

The user (Acronis Managed Machine user) should also have full access to the backed up folders, subfolders and files.

Thank you,
