Virtual data backup best practices: Shared storage and snapshots
This article is part of the Virtual Data Center issue of May 2009, Vol. 10
When it comes to virtual data backup, IT administrators face a constant dilemma. They need to protect an increasing number of servers in less time, with fewer staff, risking little -- if any -- data loss. At the same time, they need to maintain higher availability and user productivity while minimizing recovery time and meeting stringent reliability needs. More on virtualization backup and DR Virtual data backup best practices VM backup problems How to configure virtual server backup How to optimize server virtualization backup Virtual data protection and recovery checklist Virtual disaster recovery case study Virtualization has further complicated the problem. Consolidation means more risk, so each virtual machine (VM) hosted on a single physical host demands more acute backup attention. Although tape is the typical standby, it just isn't adequate for virtual data backup. Disk-based backups are better, using storage systems like a virtual tape library (VTL). But data centers are now rethinking their approach to virtual data ...

If it's done right, optimizing server utilization with virtualization can save data centers money.
Business-unit squabbles over server ownership and allocation are complex in virtual environments. But using virtual systems management principles, such as chargeback and capacity planning, can help.
Virtual data backup is more complicated than you're used to. New data backup best practices, such as shared storage and snapshots, will help you meet these challenges.
