My apologies for my questions as I'm a newbie with regards to web hosting via a VPS. Just wanted to ask when using a VPS which relies on a Virtual Machine (VM) on the host server, do these VMs get corrupted that often i.e., once a week, once a month, once every 6 months or once every 2-3 years? Apart from VMs getting corrupted (which means I would have to ask the VPS provider's tech support to use and restore our "VPS backup") what are some other problems a VPS user may get quite often that means they either can't logon to their VPS or have to rely on their "VPS backup" to get up and running again? Any comments or guidance would be really appreciated.
