PairTree

Pairtrees for Object Storage

Pairtree is a filesystem hierarchy for holding objects that are located by mapping identifier strings to object directory (or folder) paths two characters at a time. Pairtrees have the advantage that many object operations, including backup and restore, can be performed with native operating system tools.
