VMWare ESXi Data Recovery


Virtualization, for sure, has own specific advantages, but it adds complexity to disaster and data recovery operations. Multiple servers on a single machine and virtualization platform allow us to use hardware resources more efficiently. However, if server monitoring measures are not present, in the event of a machine crash, multiple servers may become inaccessible at the same time. It is not the first such case that we received. The customer had a host machine with VMWare ESXi hypervisor and several deployed guest servers. In this virtual environment, the thin-provisioning option was enabled. At some point, RAID1 failed and the customer tried to fix the problem by himself. Obviously, after consulting with us, the client decided to take drives for technical inspection. Failure was caused by a system related crash, but recovery of data was possible. The client did not hesitate to approve recovery of virtually archived files. So, PITS’ engineers successfully recovered all required data and gave valuable advises avoiding such problems in the future.
