Abstract
A computer-implemented method for taking snapshots in a deduplicated virtual file system may include (1) maintaining a deduplicated virtual file system that stores, at an original location within a non-virtual file system, at least one configuration file storing metadata for a target file and an extent map for the target file, the extent map defining how to construct the target file from deduplicated data segments in a deduplicated storage system, (2) receiving a request to take a snapshot of the target file corresponding to the configuration file, (3) copying the configuration file storing metadata for the target file and the extent map for the target file into a snapshot location within the non-virtual file system, and (4) transmitting a file reference request to the deduplicated storage system to add a file reference within the deduplicated storage system. Various other methods, systems, and computer-readable media are also disclosed.
