Backing up VMs: Traditional apps vs. virtual machine backup software
This article is part of the December 2011 issue of IT in Europe
Most organizations are still relying on traditional data backup and recovery software for virtual machine (VM) backup, but there are downsides to that approach. In Jacob Gsoedl's latest Storage magazine article, learn about the best way of backing up VMs, whether it's with traditional virtual machine backup options or new virtual machine backup software. In most IT shops, virtual servers are backed up just like physical servers at first, but as the number of virtual servers increases traditional backup methods start breaking down. The fact that a single physical machine can host many VMs poses challenges that simply don't exist when backing up dedicated physical servers. With multiple VMs competing for processing, storage and networking resources, contention for those resources is the No. 1 challenge of virtual server backup. Concurrent backup jobs on multiple VMs can seriously impact the performance of applications hosted on those VMs. And when traditional backup methods are used to protect virtual servers, some key ...

Don't let capacity concerns or virtualized servers bog down the performance of your storage systems. Here are 10 ways to pump up the performance of your storage arrays and networks
VMware’s latest releases suggest it has serious intentions about encroaching on storage vendors’ turf, which might be a wakeup call for the data storage industry.
If a tech is judged by the products that crop up around it and the techs it spawns, then it’s hard to argue that solid-state storage hasn’t reached a certain level of maturity.
Virtual servers and storage systems don’t have to exist in separate worlds; new tools and plug-ins provide single-console management of both virtual servers and storage.
