What does Quiesce guest file system do?
For Microsoft Windows systems, the quiescing of the file system is a process of bringing the disk data of the virtual machine computer into a state suitable for backups. This process might include such operations as flushing dirty buffers from the memory cache to disk or other higher level application specific tasks.
What does quiesce mean VMware?
What is Quiescing? According to a VMware® Knowledge Base article, “Quiescing a file system is a process of bringing the on-disk data of a physical or virtual computer into a state suitable for backups.
What does quiesce snapshot mean?
A quiesced snapshot simply gets the VM quiet so that a better snapshot can be performed. A quiesced snapshot doesn’t shut down or reboot the guest. VMware Tools is a critical component of a quiesced snapshot with the Sync driver.
How do I fix Quiescing error?
To resolve this issue, perform one of these options:
- Verify VSS, guest, and backup product configuration.
- Reduce the amount of ongoing I/O to the virtual machine.
- Opt for a crash-consistent snapshot (as opposed to application-consistent) of the virtual machine by avoiding quiescing of the file system.
What is quiesce file system?
Quiescing a file system is a process of bringing the on-disk data of a physical or virtual computer into a state suitable for backups. This process might include such operations as flushing dirty buffers from the operating system’s in-memory cache to disk, or other higher-level application-specific tasks.

What does a quiesce operation do in a snapshot?
A quiesce operation ensures that a snapshot disk represents a consistent state of the guest file systems. Quiesced snapshots are appropriate for automated or periodic backups. For example, if you are unaware of the virtual machine’s activity, but want several recent backups to revert to, you can quiesce the files.
How do I view the VMs that failed to quiesce?
You can view the VMs that failed to quiesce from the Backup History for the subclient -> right click on the Job that Completed with Errors -> View Job details -> Virtual Machine Status. Sort the list of VMs by Status, you should see Partial Success and Failure reason “Unable to quiesce” .
What is data quiescence in VMware Tools?
Data quiescence is crucial for highly-transactional applications. It helps create transactionally consistent backups or replicas and guarantee safety of application data. To create consistent backups and replicas for VMs that do not support Microsoft VSS (for example, Linux VMs), enable VMware Tools quiescence in job settings.
