Open Source File Systems

Filebench is a file system and storage benchmark that can generate both micro- and macro-workloads. It employs versatile Workload Model Language (WML) for detailed workload specification. Filebench includes several popular macro-workloads in its distribution: Web-server, Mail-server, Database-server, and others.

SynchedIn is a portable utility created to enforce realtime or latent synchronization of data (generally files) between different data storage sources. You can create as many synch configs as you please. Each synch config specifies a number of data sources, a number of schedulers. Each scheduler determines when the data sources must be checked for synchronization. Each data storage source represents a hierarchical (file system ...) or other type of data storage medium. These include hard drive, removable media, sequential devices, online storage services. Perhaps the most distinguishing quality of this utility is POP3 and IMAP storage providers which enable storage of files in a mail server, such as gmail or yahoo, in so much the same way as an online storage service (google drive, drop box ...). Storage providers could be configured for encrypted storage and specification as to what part of the underlying medium the provider represents. Components: GUI+CLI+Daemon+ConfigStorage

jmailfs is a mail based file system. It uses smtp and pop3 protocol to write, read your files on mail server.
