63616: Acronis Backup: Backup plan with replication to network folder fails with error "Archive with the same name already exists"

use Google Translate


This issue applies only to Windows 7 and Windows 2008R2

1. You create a backup plan backing up to a local folder with replication to a network folder

2. After backup runs 2-3 times, backup plan fails with the following error:

 Archive with the same name already exists.


Or Service_process crashes:

TOL: Process 'service_process.exe' has failed.



This issue occurs because of a timing issue in the Server Message Block (SMB) version 2 redirector (Mrxsmb20.sys). When this timing issue occurs, the directory cache is not updated correctly. See this Microsoft Support article for more information.


As a workaround, disable SMB2 directory cache on the machine running Windows 7 or Windows 2008R2:

  • Open Registry Editor (Win+R -> regedit) and find the following key:


Set this parameter to ZERO. If this value does not exist, create it as DWORD value and set it to ZERO.
