Join Brandon Neill for an in-depth discussion in this video Understanding snapshots, part of Up and Running with VMware vSphere 6.
- Snapshots all for me to freeze a virtual machine…at a single point in time and then make changes,…and then if I want to back out those changes,…I can go back to that earlier point in time.…Before I go into how to make snapshots,…I want to add a word of caution about snapshots.…Snapshots are not intended to be used as backups.…Running off of a snapshot for long periods of time…can significantly affect the performance…of a virtual machine.…VMware's recommendation is to only run off of snapshots…for up to 48 hours, and to have no more than eight…snapshots in a single chain.…
In addition, snapshots should never be used on virtual…machines that sync with an outside server.…For instance, exchange servers, any clustered service,…or anything that connects to an external data base.…To create a snapshot of a virtual machine…I can right click on the virtual machine,…go to "snapshots" and select, "Take Snapshot."…I give the snapshot a name, usually indicating…the changes that I intend on making to the VM, and I have…the option of snapshotting the virtual machine's memory.…
This course teaches the basics of installing, configuring, and maintaining vSphere 6, including installation of the ESXi hypervisor and vCenter Server using a pre-created environment called AutoLab. Following lab creation, Brandon Neill introduces the core components of vSphere (ESXi and vCenter) and shows how to configure storage and networking. Finally, he runs through some typical virtual-machine management tasks, such as creating a virtual machine manually vs. creating one with templates and clones, working with snapshots, and performing a vMotion migration.
