26184: Acronis Backup & Recovery 11: Acronis Storage Node Crashes if Antivirus Locks Managed Vault

use Google Translate

Last update: 08-04-2016

To solve the issue, exclude managed vault and deduplication database from the antivirus scan

This article applies to:

  • Acronis Backup & Recovery 11


  1. You are backing up to a managed vault with enabled deduplication;
  2. During the backup or immediately after it, your antvirus software starts scanning all files located in the managed vault;
  3. At this point, the Acronis Storage Node Service crashes.


Antivirus software locks the database files in the managed vault. Acronis Storage Node cannot access its database when performing post-backup indexing operations and crashes.


(!) This issue has been fixed. The fix is available in Acronis Backup & Recovery 11 Build 17437 or higher. See Installation of the latest update of an Acronis product.

To resolve the issue without installing the latest build, as a workaround, please add both the managed vault and the deduplication database to the exclusions of your antivirus software:
