UniSync

Universal offline/online direcotry sync/diff utility (C++, Multiplatform)

Search the differences of two directory structure.

Checks the directories, file sizes, modification times, and file hashes (md5,sha256). You can compare two (same time available) directory contents, or you can even compere two offline directory structures too. UniSync can create a catalog file which contains, the stucture, the sizes, hashes, etc,.. and later comperes it to another directory on a different machine too.

Syncronize two directory structure.

Checks the directories, file sizes, modification times, and file hashes (optional) and syncronioze the differences of the directories.

Creating incremental backup of a directory structure.

Because the unisync can generate an update package from a directory structure according to a catalog file it can be used to generate incremental backup of a directory tree. The only necessary thing you have to do is to create a catalog with unisync when the full backup is archived. Later the unisync can compare the data matching to the live data and create a directory as incremental backup.

Offline syncronize two directory structure.

The unisync can even syncronize two directories which can't available same time. The unisync can make a catalog from the OLD directory structure. After you tranfer this small catalog file to the second place where the NEW directory structure is located, the unisync can generate and "update package" to sync the OLD directory to same content as NEW. After you bring back the update package to the OLD directory, the unisync can apply this update. This way you can syncronize two different located not available directories with big amount of data. Of course the "update package" contains the modified and new files only.
