Using vmware and snapshots? You probably know about vmware best practices about snapshots, which includes
- The maximum supported amount of snapshots in a chain is 32. However, VMware recommends that you use only 2-3 snapshots in a chain.
- Use no single snapshot for more than 24-72 hours. Snapshots should not be maintained over long periods of time for application or Virtual Machine version control purposes.
- An excessive number of delta files in a chain (caused by an excessive number of snapshots) or large delta files may cause decreased virtual machine and host performance.
- Be especially diligent with snapshot use on high-transaction virtual machines such as email and database servers
