Unlock the partition using diskpart
- Using Acronis Backup & Recovery with using Volume Shadow Copy Service or Acronis True Image with Enabled Microsoft VSS support you back up your system;
- After the backup, the partition is locked. As a result, Database stops working, because it cannot write data to the locked partition.
VSS may lock the partition after a backup by changing the partition's attribute to read-only.
See Microsoft Knowledge Base Article 840781.
