The disclosed computer-implemented method for data placement in container-based storage systems may include (i) identifying a file stored within a container-based storage system, where the container-based storage system stores the file as data segments within containers, (ii) receiving, in response to a write operation directed to the file, a request to store within the container-based storage system a new data segment generated by the write operation, (iii) describing the file in terms of a plurality of consecutive slabs, (iv) determining that the new data segment falls within a specified slab, and (v) fulfilling the request to store the new data segment within the container-based storage system by storing the new data segment in a designated container that corresponds to the specified slab in response to determining that the new data segment falls within the specified slab. Various other methods, systems, and computer-readable media are also disclosed.

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.
