重删型快照需要相对较少的存储空间,且创建时间也较短。因此十分适合需要在多个时间点频繁创建快照的情况。文章介绍了重删型快照技术的优势,以及在浪潮存储产品中的应用。随着数据容量和速度加速增长,用户对数据不间断可用性程度需求更高,以便保持系统升级、迁移和合并的不间断。快照是一种保证数据连续可用性的有效途径,在某一时刻对一定规模的数据采集获取它们的状态,对其快速地进行在线映像或者拷贝。快照可以在不中断当前业务的情况下生成存储系统在某时间点即时一致的数据镜像。
Deleted snapshots require a relatively small amount of storage space and a short creation time. So it’s great for situations where you need to create snapshots frequently at multiple points in time. The article describes the advantages of deduplication snapshot technology and its application in Inspur storage products. As data capacity and speed grow faster, there is a greater need for uninterrupted availability of data to keep systems up-to-date, migrate, and consolidate. Snapshots are an effective way to ensure the continuous availability of data, obtaining their status at a certain moment for a certain amount of data acquisition, and quickly performing an online image or copy. A snapshot can generate an instant consistent data mirroring of a storage system at a certain time without interrupting the current service.
