ArchiverFS

The file archiving solution for file servers and network file storage systems that lets you use any device as second tier archive storage, while only requiring a tiny footprint on the host system. Featuring full support for cloud, DFS, replication, de-duplication, and compression ArchiverFS lets you use any NAS, SAN or cloud platform as storage for your old unstructured files. If you can share it to the network with a UNC path and format it with NTFS (or REFS) then you can use it as second line storage.

Unlike other file archiving software ArchiverFS doesn't use a database to store files, pointers to files or file meta data. We use pure NTFS (or REFS) from start to finish. It is this approach that gives ArchiverFS it's tiny footprint on the host system.
