Resync

Non-destructive local folder synchronizer.

Features

Efficiently synchronizes big file trees between local disks without computing checksums.
Processes the updated, changed, moved, removed and added files independently.
Allows to include/exclude files by folder, name or path using wildcards.
Stores replaced and removed files.

Limitations

Symbolic links are not processed.

resync --create --different --store STORE_FOLDER/ SOURCE_FOLDER/ TARGET_FOLDER/

resync --create --updated --changed --removed --added --emptied --confirm SOURCE_FOLDER/ TARGET_FOLDER/

resync --updated --changed --removed --added --moved --emptied --verbose --confirm SOURCE_FOLDER/ TARGET_FOLDER/

Finds the updated/changed/removed/added/moved files and the emptied folders, then prints these changes and asks confirmation before applying them to the target folder.
