Abstract: Maintenance of plural active file systems (100), wherein each of the active file systems initially access data (120) with another of the active file systems, and wherein changes made to each of the active file systems are not reflected in other active file systems. When a second active file system is created based on a first active file system, the first active file system and the second active file system initially share data. When changes are made to the first active file system, modified data is recorded in the first active file system in a location that is not shared with the second active file system in a location that is not shared with the second active file system. When changes are made to the second active file system, modified data is recorded in the second active file system in a location that is not shared with the first active file system. Also, creation of the plural active file systems.

Abstract translation: 维护多个活动文件系统（100），其中每个活动文件系统最初与另一个活动文件系统访问数据（120），并且其中对每个活动文件系统所做的更改不会反映在其他活动文件系统 。 当基于第一活动文件系统创建第二活动文件系统时，第一活动文件系统和第二活动文件系统最初共享数据。 当对第一活动文件系统进行改变时，修改的数据在不与第二活动文件系统共享的位置处不与第二活动文件系统共享的位置记录在第一活动文件系统中。 当对第二活动文件系统进行改变时，修改的数据被记录在不与第一活动文件系统共享的位置的第二活动文件系统中。 另外，创建多个活动文件系统。
