When you enable background snapshots, you can continue working while Workstation Pro preserves the state of a virtual machine. A progress indicator for the background snapshot appears in a corner of the Workstation Pro window.
Important:
Enabling background snapshots for a host with slow hard disks can adversely affect performance. If you experience significant performance problems when taking or restoring snapshots, disable background snapshots.
Prerequisites
On a Linux host, run Workstation Pro as the root user. Only root users are allowed to change background snapshot settings.
