Varian公司开发出高效快速的肿瘤学资料恢复软件

在面临系统断电或者灾难的时候，一种新型资料保护服务可以为肿瘤信息系统用户提供关键资料的持久保护。

这套高度可靠快速恢复保护(HARRP)系统是由Varian公司(Palo Alto, CA, USA)研发的，专门设计用于Varis可视肿瘤学信息系统，该系统也是由Varian公司开发的。HARRP以NSI软件公司的Double Take软件工艺为基础。配备HARRP使得依赖数据的肿瘤科，在面临日复一日地错误或者网络服务器灾难地时候，能够快速简便地拯救Varis数据。

Varian肿瘤信息系统副总裁Christopher Hanna博士解释说：“接受放疗的时候，每个患者的治疗方案在保护周围健康组织的同时，都寻求最大剂量来治疗肿瘤。治疗方案视根据患者大量解剖资料和治疗计划来制定的。医生一定不期望在患者来接受每日常规治疗的时候，发现患者资料已经丢失了。HARRP将确保这种情况不会发生。”

使用HARRP技术，在服务器崩溃的时候，治疗中心能够备份而且在1小时之内启动。该系统在共享或者私人Internet protocol(IP)协议为基础建立的网络，当数据发生字节水平的变化的时候就复制数据。数据变化几乎即刻捕获，当需要的时候可以提供最新拷贝的数据。在主要服务器断电的时候，软件允许附属服务器在按下按钮之后即可开始工作。
 
Data Recovery Software for Oncology
 
A new data-protection service is designed to provide users of an oncology information system with continuous protection for critical data in the event of a system outage or disaster.

The High Availability and Rapid Recovery Protection (HARRP), developed by Varian Medical Systems, Inc. (Palo Alto, CA, USA), is designed for use with the Varis Vision oncology information system, also developed by Varian. HARRP is based on NSI Software, Inc.’s (Hoboken, NJ, USA) Double Take software technology. HARRP is devised to enable data-dependent oncology departments to recover Varis data rapidly and easily when there are day-to-day failures or disasters involving network data servers.

“For radiation therapy, each patient’s treatment seeks to maximize the dose to the tumor, while protecting the surrounding healthy tissues,” explained Christopher Hanna, Ph.D., vide president of Varian’s oncology information systems. “Treatments are based on a mountain of data about the patient’s anatomy and treatment plan. You do not want a patient showing up for a daily treatment, and finding that you cannot proceed because of data loss. HARRP will help to ensure that doesn’t happen.”

With HARRP technology, if a server crashes, a treatment center can be back up and running within one hour. The system replicates changes in data as they happen at the byte level over a shared or private Internet protocol (IP)-based network. Changed data are captured almost immediately, and an up-to-date copy of the data can be accessed when needed. In the even of a primary server outage, the software enables a secondary server to stand in with the push of a button.
