Hi<br />
<br />
I know this is an old question, but I had stopped looking at EE for a while.<br />
<br />
The replicated datastore are literally SNAPSHOTS of the source datastore, snapshot here is being used to indicate a COPY of the original at a point in time.<br />
<br />
They are prefixed with snap- so that the user is able to differentiate them from the originals.<br />
<br />
When a VMFS is created, the value of the device NAA as well as timestamp is added to the metadata, every time ESXi mounts the device, it checks that the NAA in the metadata matches the device it is on, if not, it is called a snapshot, a copy.<br />
<br />
Is this a sufficient explanation? I talk for hours about this but I am trying not to overload things.<br />
<br />
Good luck.

Why VMware SRM replicated datastores named with the snap prefixes

Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.

Virtualization

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.
