工作站数据备份管理系统的实现

大庆物探公司研究所有41套工作站，4台磁带机，它们承担着公司二十几个区块的地震资料解释任务，工作非常繁忙。为了避免因数据丢失而影响生产甚至造成无法估量的损失，必须及时地对解释数据进行备份。现有的4台磁带机要供41套工作站使用，不同的工作站备份时就要挪动磁带机，工作起来极不方便。我们开发的“工作站数据备份管理系统”比较好地解决了这一问题，实现了41台工作站共享4台磁带机，每个用户在不挪动磁带机的情况下能随时备份，收到良好的效果。

Realization of data back-up management system in workstation

There are 41 sets of workstation and 4 magnetic tape units in Research Institute of Daqing Geophysical Exploration Company, which take on seismic data interpretation in more than twenty blocks of Geophysical Exploration Company and are very busy. It's necessary to make back-up of the interpreted data in order to avoid the data losses that has influence on production and makes even uncountable losses in production. The available 4 magnetic tape units support 41 sets of workstation, which are inconvenient for moving magnetic tape unit when different workstation makes back-up. The developed data back-up management system by us can better solve the problem, realizing 41 sets of workstation sharing 4 magnetic tape units, that can make data back-up at any time without moving magnetic tape unit for each user and has good results.
