在面臨系統(tǒng)斷電或者災(zāi)難的時(shí)候，一種新型資料保護(hù)服務(wù)可以為腫瘤信息系統(tǒng)用戶提供關(guān)鍵資料的持久保護(hù)。

這套高度可靠快速恢復(fù)保護(hù)(HARRP)系統(tǒng)是由Varian公司(Palo Alto, CA, USA)研發(fā)的，專門設(shè)計(jì)用于Varis可視腫瘤學(xué)信息系統(tǒng)，該系統(tǒng)也是由Varian公司開(kāi)發(fā)的。HARRP以NSI軟件公司的Double Take軟件工藝為基礎(chǔ)。配備HARRP使得依賴數(shù)據(jù)的腫瘤科，在面臨日復(fù)一日地錯(cuò)誤或者網(wǎng)絡(luò)服務(wù)器災(zāi)難地時(shí)候，能夠快速簡(jiǎn)便地拯救Varis數(shù)據(jù)。

Varian腫瘤信息系統(tǒng)副總裁Christopher Hanna博士解釋說(shuō)：“接受放療的時(shí)候，每個(gè)患者的治療方案在保護(hù)周圍健康組織的同時(shí)，都尋求最大劑量來(lái)治療腫瘤。治療方案視根據(jù)患者大量解剖資料和治療計(jì)劃來(lái)制定的。醫(yī)生一定不期望在患者來(lái)接受每日常規(guī)治療的時(shí)候，發(fā)現(xiàn)患者資料已經(jīng)丟失了。HARRP將確保這種情況不會(huì)發(fā)生?！?/P>

使用HARRP技術(shù)，在服務(wù)器崩潰的時(shí)候，治療中心能夠備份而且在1小時(shí)之內(nèi)啟動(dòng)。該系統(tǒng)在共享或者私人Internet protocol(IP)協(xié)議為基礎(chǔ)建立的網(wǎng)絡(luò)，當(dāng)數(shù)據(jù)發(fā)生字節(jié)水平的變化的時(shí)候就復(fù)制數(shù)據(jù)。數(shù)據(jù)變化幾乎即刻捕獲，當(dāng)需要的時(shí)候可以提供最新拷貝的數(shù)據(jù)。在主要服務(wù)器斷電的時(shí)候，軟件允許附屬服務(wù)器在按下按鈕之后即可開(kāi)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.
