Yes, but the Question also is WHY ?<br />
<br />
for what purpose, applying patches ?<br />
<br />
Performance when writing to a delta disk is worse, and performance can be terrible.

I should have put it differently. Because there is a sql server on it, won't the data get corrupted in the snapshot?<br />
Problem now is that snapshot won't work &quot;error occured while quescing the virtual machine&quot; but I do wonder if reverting to a snapshot would be revelant.

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.
