pirsyncd 20110412

pirsyncd is a daemon to watch a directory for kernel’s inotify events and then execute an rsync command to synchronize two different directories (local or remote).

This is a poor man’s mirroring or an alternative (not so) real data replication mechanism and it is based on Pyinotify.

pirsyncd monitors for these inotify events:

 * IN_ATTRIB
 * IN_CLOSE_WRITE
 * IN_CREATE
 * IN_DELETE
 * IN_MODIFY
 * IN_MOVED_TO
 * IN_MOVED_FROM
 * IN_DELETE_SELF

· Ability to check and stop the daemon
· Syntax help with ––help
· For every parameter there is a usage examples with ––examples
· Support multiple running instances
· Mirroring to a remote (destination) server (needs password-less connection) through ssh connection
· Mirroring to a remote (destination) server (needs rsync password-file) through rsync connection
· Error handling via exceptions
· A customized delay for mirroring directories (dont rsync asap when an event is trigged)

· Logging functionality of rsync process
· Partial rsync functionality
· Append rsync functionality
