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

use Google Translate


  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


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.


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