55 Dell Virtual Storage Manager: Installation Considerations and Local Data Protection | 2079-BP-V-VSM
Note: While VMware snapshots can be non-disruptive, selecting Quiesce guest file system invokes a process to bring
the virtual machine disks into a state suitable for backups. Depending on how active the data is and the application in
use, this may cause disruption.
7.3 Additional vVol snapshot functionality with VSM
In a somewhat confusing circular fashion, VSM builds on the VMware snapshot functionality that also enables vSphere
to perform. This allows vSphere administrators to extend snapshots to groups of virtual machines, have more granular
scheduling options, and use additional restore options.
7.3.1 Protecting groups of virtual machines
Often multiple virtual machines are involved in supporting an application. For example, a web-based application may
have one or more web servers, a database backend, and a file server. There are times when it will be appropriate to
have a snapshot of the entire application stack at the same time. VSM builds on the VMware hardware-assisted
snapshots and provides this functionality. To enable a snapshot of a group of virtual machines at the same time, they
must be placed within a virtual machine folder.
Note: The VSM interface can be used to snapshot folders of virtual machines, or individual virtual machines.
1. From the virtual machine folder context sensitive menu, or its Actions dropdown menu, select All Dell VSM
Actions > Create Snapshot.
