Instructions on how to enable Microsoft native VSS instead of the default Acronis VSS in Acronis Backup

This article applies to:

  • Acronis Backup 11.5 (Acronis Backup & Recovery 11.5)
  • Acronis Backup & Recovery 11

(!) If you are using Acronis Backup & Recovery 10, see Acronis Backup & Recovery 10: Using Microsoft VSS instead of Acronis VSS.

Introduction

By default, Acronis Backup & Recovery 11 uses Acronis VSS Provider which interacts with Microsoft VSS to create volume shadow copies of the data. However the actual VSS snapshot created by Microsoft VSS is not used: Acronis Backup & Recovery 11 uses its own snapshot.

Acronis Backup 11.5 has Microsoft VSS provided selected by default.

Troubleshoot VSS-related issues with the free Acronis VSS Doctor tool. If it didn't help and you still need to switch the VSS provider to Microsoft VSS, follow instructions below.

Solution

  1. To set Microsoft VSS usage for all backup jobs, go to Options -> Default backup and recovery options -> Default backup options.

    To set Microsoft VSS usage for a backup plan, create a new backup plan or open an existing backup plan for editing, then go to Plan parameters -> Backup options.

  2. In Options window, go to Volume Shadow Copy Service section. Make sure that the option Use Volume Shadow Copy Service (VSS) is selected. In Snapshot provider menu select the option Software - System provider:

(!) If you are using Microsoft VSS, make sure that:

  • Acronis Managed Machine Service is running under account with Administrator rights (hit Win-R and in the Run window type services.msc. In Services window, locate Acronis Managed Machine service and look in Log on as column: this account must be a member of Administrators group)
  • Make sure the task is launched with Administrator credentials: in Create/edit backup plan window go to Plan parameters and press Show plan's credentials, comments, label. Look under Plan's credentials: the specified account needs to belong to Administrators group.
