用户使用磁带设备的根本目的就是对数据进行备份,备份数据的可靠性是用户购买磁带设备进行存储时最关心的问题,而这一点也是磁带设备优于磁盘的主要因素。同时随着近两年来数据信息的爆炸性增长,用户对备份数据量的需求幅度大幅提高,低端市场开始出现上移,DDS技术的逐渐淡出充分证明了这一点。另外,相对日益增长的数据备份量,企业能够用于备份的时间却在逐渐减少。随着业务全球化的加剧,更多的企业业务转变为7天×24小时的运作方式,用户能够用于对数据管理、备份的时间变得越来越少。面对需求的升级,业界在不断努力,具体体现在:磁带设备的纪录密度和速度的发展正在呈倍数提高,存储量的计算已经开始从10GB上升到几十甚至上百个GB,而存储的速度得到了大幅的提升。从而帮助企业能够以更小的空间保存更多的数据量,以最短的时间备份最多的数据量。各磁带技术都在不断的实现各种技术
The fundamental purpose of users to use tape devices is to back up the data, the reliability of backup data is the most concern when users buy tape devices for storage, and this is the tape device is better than the main factor of the disk. At the same time, with the explosive growth of data and information in the past two years, the demand for backup data has risen sharply, and the low-end market has started to move upward. The gradual dilution of DDS technology proves this point. In addition, the relative amount of data backups is growing and the time it takes for the enterprise to back up is decreasing. As business globalization intensifies, more business operations are transformed into seven days and 24 hours of operation, allowing users to manage data and reduce backup times. The face of the escalation of demand, the industry continues to work, embodied in: tape device recording density and speed of the development is exponentially increased, the calculation of storage capacity has begun to rise from 10GB to tens or even hundreds of GB, and storage Speed has been greatly improved. Thus helping enterprises to save more data in less space and back up the most amount of data in the shortest time. Various tape technologies are constantly implementing various technologies
