Synchronize local directories with FTP servers.
|Version:||3.1, Date: Mar 15, 2020|
Major version updates (1.0 => 2.0, 2.0 => 3.0, …) introduce breaking changes to the previous versions. Make sure to adjust your scripts accordingly after update.
- This is a command line tool…
- … and a library for use in custom Python projects.
- Recursive synchronization of folders on file system and/or FTP targets.
- Upload, download, and bi-directional synchronization mode.
- Configurable conflict resolution strategies.
- Unlike naive implementations, pyftpsync maintains additional meta data to detect conflicts and decide whether to replicate a missing file as deletion or addition.
- Unlike more complex implementations, pyftpsync does not require a database or a service running on the targets.
- Optional FTPS (TLS) support.
- Architecture is open to add other target types.
The command line tool adds:
- Runs on Linux, OS X, and Windows.
- Remember passwords in system keyring.
- Interactive conflict resolution mode.
- Dry-run mode.
- The FTP server must support the MLSD command.
- pyftpsync uses file size and modification dates to detect file changes. This is efficient, but not as robust as CRC checksums could be.
- pyftpsync tries to detect conflicts (i.e. simultaneous modifications of local and remote targets) by storing last sync time and size in a separate meta data file inside the local folders. This is not bullet proof and may fail under some conditions.
- Currently conflicts are not detected, when a file is edited on one target and the parent folder is removed on the peer target: The folder will be removed on sync.
In short: Make sure you have backups.
