I was classing corruption and failure as 2 different things in this instance. So their view on failure would stand true, but possibly not for corruption.

If's corrupt the replicated data would also be corrupt.

If's corrupt the replicated data would also be corrupt.

<div class="content wysiwyg-content">
If a VM is replicated over 2 sites (2 unique SAN's), if the VMDK hosting the OS, apps, databases and DB backups in the primary site corrupts for whatever reason - will the corruption also be replicated to the copy on the other site? Our admin is writing backups to a local drive on a VM, he claims if the hardware (i.e. SAN) failed then he wouldn't lose both the online DB and the backup as the copy on the other SAN would stay in tact. Yet I wasn't sure if the same rules apply for corruption as opposed infrastructure failure?

VM replication and corruption

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.

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.
