    SynchedIn

    To synch and encrypt all sorts of data across different sources

    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
