File::Rsync::Mirror::Recent Description

Mirroring via rsync made efficient File::Rsync::Mirror::Recent is a Perl module that offers a speeding up rsync operation on large trees. Uses a small metadata cocktail and pull technology.rersyncrecent solves this problem with a couple of (usually 2-10) lightweight index files which cover different overlapping time intervals. The master writes these files and the clients/slaves can construct the full tree from the information contained in them. The most recent index file usually covers the last seconds or minutes or hours of the tree and depending on the needs, slaves can rsync every few seconds or minutes and then bring their trees in full sync.The rersyncrecent model was developed for CPAN but as it is both convenient and economic it is also a general purpose solution. I'm looking forward to see a CPAN backbone that is only a few seconds behind PAUSE. Requirements: · Perl Limitations: · If the tree of the master server is changing faster than the bandwidth permits to mirror then additional protocols may need to be deployed. Certainly p2p/bittorrent can help in such situations because downloading sites help each other and bittorrent chunks large files into pieces.
