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.

How do I fix Quiescing error?

To resolve this issue, perform one of these options:

1. Verify VSS, guest, and backup product configuration.
2. Reduce the amount of ongoing I/O to the virtual machine.
3. Opt for a crash-consistent snapshot (as opposed to application-consistent) of the virtual machine by avoiding quiescing of the file system.

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.
