58237: [Fixed] Acronis Cyber Protect Cloud / Acronis Cyber Backup Service: Backup Fails with "Key not valid for use in specified state"

Last update: Fri, 2020-05-01 06:16

Symptoms

  1. You create a backup plan and set up encryption.
  2. After a while, you change the user running Acronis Managed Machine Service on the protected machine.
  3. Backup fails with:

| Error
| Backup failed

| Key not valid for use in specified state
| Error code: 65520
| Module: 0
| LineInfo: 0x36E942E8021F4B85
| Fields: {"$module":"security_core_vsa64_2406","code":"2148073483"}
| Message: Key not valid for use in specified state

Cause

Current security design permits read/write operations with backups exclusively to the encryption key owner. This means that subsequent backups have to be executed by the user that set the encryption key.

Solution

The issue has been fixed in Acronis Cyber Protect Cloud 7.5, please update to the latest build.
