FILESYSTEM RECOVERY AND INDEXING WITHIN A USER SPACE

原文（中国語）

Methods, systems, and devices for data management are described. A data management system (DMS) may support backup and recovery of a filesystem. The DMS may, as part of the backup, obtain a snapshot of the filesystem. The DMS may mount the snapshot within a user space of a node of the DMS. The user space may be isolated from other processes that execute on the node of the DMS. The DMS may generate, within the user space based on the mounted snapshot, index files that index the filesystem. In response to a subsequent request to access one or more files, the DMS may retrieve the one or more files from the snapshot mounted in the user space based on the index files.
