Backup process can be divided into several stages:

Introduction

Make sure that your problem appears during file-level backup only. This is the case if you also tried to run a Disk level backup

  • of the same source (e.g. backup of the whole C: drive)

  • with the same backup settings (VSS, etc)

and in the result the disk level backup worked. In this case check for known issues.
