4625 Audit Failure messages on data share server
I just installed 11.5 and scheduled a series of backups for local workstations. The backups are being stored on a file share on a Windows2008R2 server. The backups run and appear to be error free however on the server where the share is located, there are a number of Audit Failures for logins related to each PC being backed up. These audit failures are being red flagged by the security audit team. I have deleted the backup jobs and created new ones checking and double checking the credentials for the backup administrator with no success. As a test I created a centralized vault location on same file server as the share and redirected the backup to that vault and the Audit Faults ceased. This however is not a permanent solution. Below is the text of one of the errors.

The Process Information fields indicate which account and process on the system requested the logon.
The Network Information fields indicate where a remote logon request originated. Workstation name is not always available and may be left blank in some cases.

Our scenario is the same. We too have a third party providing the EBR software. I thought I found that if I setup data vault rather than write to a share I do not see that error but today I tried again to confirm and I do see the error even to a managed vault.
Hello Gregory, Kevin,
this issue is a known one and it is being worked on. According to development you can simply ignore these messages, because they don't affect anything.
Thank you,
Greetings Anna Trifonova,
It is a pain for us to receive these messages because they fill up our Security log file which may cause us to miss a valid event. I would really like for a workaround to be considered. I'm curious to know if adding the local "ANONYMOUS LOGON" group with "Read Only" permissions to the Windows network folder would solve the problem and if it would be an acceptable practice by Acronis. Please let me know your thoughts. Thank you for your help.

Hi Chad,
at the moment there is no available workaround, but I understand your concern and I'll forward your feedback to development.
Thank you,
The fix below was provided to me and it appears to have corrected the issue.
1. Open Registry editor (Start > run > regedit.exe)
2. Create a key [DWORD] HKLM\SOFTWARE\Acronis\Global\Configuration\UseServiceCredentialsForShareAccess = 1
3. Restart Acronis Managed Machine Service service (Start > run > services.msc)
4. Check how the backup is working
