Projects / pybag


PYBAG implements a portable bag and is intended for fast synchronization and backup. It lets you use a portable digital storage device to carry your electronic documents similar to the way you can use a bag to carry paper documents. You can synchronize the bag with your original files easily. If a synchronization conflict occurs, it will be reported. You can specify rules for automatic conflict resolution. With PYBAG, you can backup files and synchronize any changes made to the original files with the bag. The synchronization process will only copy changed files. The program is cross-platform and independent from the OS and filesystem. You may easily synchronize files between Windows and Linux, for example. Symbolic links are supported on all systems (if the OS or filesystem does not support symlinks, then they are emulated). This program has a GUI and a command line interface.

        Release Notes: Serious speed optimization was done. The second synchronization for 24 GB of backed-up files takes only 4 minutes on the author's system. In the GUI, the tree list was replaced by a fast file list, making the GUI faster. A backup mode was added, which performs one-way synchronization two times faster than the standard mode. Report filters for compared items were added. You can specify filters for items and change the report format. The CLI menu was improved.
