![]() ![]() A 2 TB virtual disk is hence split into 1,024 files of 2GB size. It results in splitting VMDK files into 2GB files. Unfortunately VMware uses a really dumb default setting that most users ignore. After the snapshot is created, the original VMDK remains untouched. Once you ‘freeze’ a virtual machine by taking a snapshot of it, VMware stops writing disk changes to the original virtual disk and starts a new virtual disk file instead. For each VMDK (the virtual machine’s hard disk file), for example, and each snapshot you take for the VM, there will be a new VMDK. VMware implements snapshots by saving the virtual disk and the virtual machine’s internal memory state, among other things, into separate files, so-called snapshot files. But how is this done internally? Therein lies the answer as to why you shouldn’t perceive snapshots as a backup mechanism. ![]() Naturally, this feature is very popular with software developers and software testers because it allows them to repeat tests with all tests having the exact same defined starting point and system conditions. What is a VMware Snapshot?Ī snapshot in VMware is a mechanism that allows the user of the virtual machine to ‘freeze’ the machine and go back to that frozen state at a later point in time. First of all, you need to be aware of what snapshots and the AutoProtect features do and not do, in order to make an informed decision. The reasoning and alternatives are outlined below. VMware and all other virtual platforms do not recommend using VMware Snapshot or AutoProtect Snapshot features to function as VMware backup for virtual machines. ![]()
