Also, you might see a delay in the amount of time it takes the virtual machine to power on. Performance degradation is based on how long the snapshot or snapshot tree is in place, the depth of the tree, and how much the virtual machine and its guest operating system have changed from the time you took the snapshot.

Snapshots can negatively affect the performance of a virtual machine.

Also, large numbers of snapshots are difficult to manage, consume large amounts of disk space, and are not protected if there is hardware failure. If the files containing a virtual machine are lost, its snapshot files are also lost.

Snapshots provide a point-in-time image of the disk that backup solutions can use, but Snapshots are not meant to be a robust method of backup and recovery.If your virtual machine currently has snapshots that prevent you from configuring bus sharing, delete (consolidate) the snapshots. If you require bus sharing, consider running backup software in your guest operating system as an alternative solution. VMware does not support snapshots of virtual machines configured for bus sharing.Snapshots are not supported with PCI vSphere DirectPath I/O devices.Quiesced snapshots require VMware Tools installation and guest operating system support.Powered on virtual machines with independent disks cannot support memory snapshots. Virtual machines with independent disks must be powered off before you take a snapshot.VMware does not support snapshots of raw disks, RDM physical mode disks, or guest operating systems that use an iSCSI initiator in the guest.Snapshots are useful as short-term solutions for capturing point-in-time virtual machine states and are not appropriate for long-term virtual machine backups. Snapshots can affect the virtual machine performance and do not support some disk types or virtual machines configured with bus sharing.
