San Diego大学大师VM备份和恢复量子

更好的备份虚拟机和储蓄超过1美元Million

San Diego大学IT人员是虚拟化的早期支持者，今天的近98％的服务器是VM。当员工看到他们的遗产备份和灾难恢复系统无法再保持时，团队知道它必须寻找更好的解决方案。

备份太长了

“我们到了一个人根本无法获得备份的观点，”USD的网络基础设施系统和服务经理Mike Somerville Mike Somerville说，“我们开始认真地看待另一种选择。”

The initial stage of the disk-to-disk backup was a layer of NAS filers which became much too expensive to maintain, and, explains Christopher Wessells, University Vice-Provost and CIO, “all the estimates for what we would have to pay in upcoming years were going through the roof.”

最终的主要问题正在改善恢复操作，特别是对于VM。从磁带恢复数据时，它可能需要数小时甚至几天，并且即使数据在磁盘上也恢复VMS总是慢。“在我们可以用它做任何事情之前，每个VM恢复必须由备份应用程序进行备份应用程序，并且在时间太多时间，”Somerville说。

解决方案研究导致DXI和VMPRO

“We analyzed software-based solutions and various kinds of appliances, and the clear conclusion from a scalability standpoint, a performance standpoint, and from a cost reduction standpoint were the Quantum solutions,” explains Wessells.

Ultimately the solution that USD selected had two parts—a Quantum DXi deduplication appliance and its vmPRO backup software for virtual servers.

Backup Performance Issues Solved

新系统立即解决了备份窗口问题。“之前，我们无法及时完成备份，现在我们每周都会回到备份一切 - 我们有很多余量，让我们在增加时让我们处理更多数据，”Somerville说。“我认为我们已经获得了两个可用备份窗口的全天。”

The deduplication rates have been impressive; today the current ratio is a full 22 to 1, so that 14TB of DXi space is all that’s needed to store 300TB of backup data.

Better Backup & Recovery for VMs

量子’s vmPRO is an agentless backup system that integrates with vCenter, using virtual appliances to create fast backup images of VMs in native format.

“The vmPRO solution has been absolutely amazing,” Somerville reports. “We installed it, and it really just worked out of the box. We were actually doing a test between our current backup software and this new system, when a restore request came in, so we used both. The vmPRO unit was immediately available. The other one was still churning two hours later.”

Lower Costs Friendly on Budget

“不仅是DXI比购买企业磁盘价格便宜，而且它比坦率地坦率地不太好的竞争产品不如不太好，”Somerville说。

“Primary enterprise storage costs us about $2,500 per terabyte, so our 22 to 1 dedupe ratio saves us $52,000 in direct costs,” Wessells explains. “We estimate a cost reduction in excess of one million dollars over a three year period.”
