Known issues and limitations
Acronis Cyber Protect Cloud
Autodiscovery and remote installation
- [ADP-39185] Active Directory-based discovery does not operate as expected with the default configuration of Windows Server 2025 because it enforces LDAP encryption by default.
- Solution: See this KB article.
Backup
-
[ABR-408680] Proxmox VE: When performing parallel backup operations with 2 or more Linux-based Proxmox VMs, which contain LVMs and XFS file system inside, the backup activities may become unresponsive in some cases.
-
Solution: Reduce the number of parallel VM backups in corresponding protection plan (Backup options -> Scheduling)
-
- [ABR-365442] The backup validation completes successfully, but the validation status is incorrect or missing in backup sets with a large number of backups.
- [ABR-361097] It is possible to create backups with special characters in their names, but such backups are not accessible when saved on a network storage.
- Solution: Do not use special characters in backup names, even though the application allows you to.

Recovery
- [ABR-371521] When browsing backup archives, the sorting of files by last change date does not work correctly.
