Quiesced Snapshot of Instance Cannot Be Created
Product version: 9.3
Last modified: 19 May 2020
The following error message appears:
Quiesced (application-aware) snapshot of this instance cannot be created.
When the application-aware mode is enabled, the snapshot works as follows:
NAKIVO Backup & Replication injects a runtime VSS Driver into the instance.
NAKIVO Backup & Replication requests the VSS Driver to create a quiesced snapshot.
VSS Driver uses VSS inside a Windows instance to freeze I/O requests of applications inside the OS.
If OS quiescing fails to create an application-consistent snapshot, NAKIVO Backup & Replication displays this error.
The error may be caused by:
Incorrect credentials to the instance
Insufficient level of permissions
Incorrect configuration of the instance security group
Incorrect Windows firewall configuration inside the instance
Incorrect configuration of the instance OS
