SubShare synchronizes your data

SubShare follows the Unix principle "Do one thing and do it well." Therefore the feature list is pretty short: Synchronize files and directories between computers.
However, even this one single task involves many details: Cloudstore is...
  • ... fast
    SubShare copies only modified data. If a file is not modified, it is not copied. If a file is large and only a small part of it is modified, only this small part is copied. If a file is moved or renamed, it is not copied over the network - instead, the move operation is imitated on all remote repositories.
  • ... secure
    SubShare uses strong encryption and a sophisticated, password-less authentication mechanism. Read more about this on the Security page.
  • ... easy to use
    Due to its unique approach to security, the initial setup is done in a few seconds (no cumbersome password management). And once set up, SubShare synchronises data in the background. You don't need to do anything, anymore.
  • ... robust
    SubShare does everything possible to prevent data loss: For example, it detects collisions and resolves them; also if a data transfer is interrupted, SubShare resumes it later.
  • ... flexible
    Synchronise a repository with as many other repositories as you want. You can synchronise a sub-directory only, too (e.g. sync only a small part of your server's huge repository to your notebook).
  • ... test-driven and clean code.
    Fellow developers might appreciate that SubShare is test-driven and - please see for yourself - clean code.
