Free rsync software for linux

drsync is a Perl wrapper for rsync which keeps track of the filelist between synchronizations. drsync project is ideal for notebook users who want to keep data in two (or more) different places.

It is also good for the Linux PDAs (Agenda, iPAQ, Yopi, etc.), to keep data synchronized with the desktop.

librsync is a free software library that implements the rsync remote-delta algorithm. This algorithm allows efficient remote updates of a file, without requiring the old and new versions to both be present at the sending end.

The library uses a "streaming" design similar to that of zlib with the aim of allowing it to be embedded into many different applications.

librsync is currently pre-1.0, with most important functionality working.

librsync is not wire-compatible with rsync 2.x, and is not likely to be in the future.

This is a new codebase, designed to allow a fresh start on the problem and a cleaner design. It may be used in a future version of rsync or a successor project. Early steps towards that are visible in Waynes rZync prototype, and Martins superlifter design.

The librsync project was created by Martin Pool and is now being enhanced and finished by the folks you can find on the project page.

The librsync algorithm is based on the well-known and trustworthy rsync software by Andrew Tridgell.

Rsync::Config is a Perl module for rsync configuration generator.

Rsync::Config is a module who can be used to create rsync configuration files. A configuration file (from Rsync::Config point of view) is made by atoms and modules with atoms. A atom is the smallest piece from the configuration file. This module inherits from Rsync::Config::Module .

INHERITANCE

Objects from Rsync::Config inherits as in the next scheme

/--- Rsync::Config::Module --- Rsync::Config

Rsync::Config::Renderer

--- Rsync::Config::Blank
/

Rsync::Config::Atom --- --- Rsync::Config::Comment

SYNOPSIS

use Rsync::Config;
use Rsync::Config::Atom;
use Rsync::Config::Module;

sub main {
my ($conf, $module);

$conf = new Rsync::Config();
$conf->add_comment(Main configuration file for our rsync daemon);
$conf->add_atom(read only,yes);
$conf->add_atom(chroot,yes);

$module = new Rsync::Config::Module(name => cpan);
$module->add_atom(path,/var/ftp/pub/mirrors/ftp.cpan.org/);
$module->add_atom(comment, CPAN mirror);

$conf->add_module($module);
$conf->to_file(/etc/rsyncd.conf);
}

Rsync Vault Manager is an archive manager that uses rsync to manage backups of multiple clients across multiple logical partitions (vaults).
Rsync Vault Manager has some features that some other rsync-based backup schemes lack, such as being written in C++, needing no scripts or other programs than rsync and any binaries on which rsync depends (such as SSH), the ability to manage multiple instances of rsync connections to separate clients in parallel, the ability to use multiple logical partitions (vaults) in a configurable fashion for purporses of redundancy and added reliability, and the use of hard links for files that have not changed from one archive to the next.
Rsync Vault Manager was developed on an x86 platform using Linux RedHat 9.0 w/ GCC 3.2.2 and an UltraSPARC platform using Solaris 8 w/ GCC 2.95.5.
Rsync Vault Manager uses GNU autoconf/automake scripts for compilation and installation.
Enhancements:
- Minor bugs fixed: a wildcard resolution bug, incorrect archive directory names, empty job IDs in reports, and this release checks that a vault is writable before running rsync.
- A vault locking option prevents multiple instances of rvm from using the same vault, there is a separate error logging level to be used when retrying an rsync command, and there is an option to delete old log files along with old archives.

File::RdistByRsync is a Perl module that can read rdist distfiles, emulate using rsync.

SYNOPSIS

use File::RdistByRsync

@dist_blocks = parse_rdist($distfile, %options)

($args, $extras, @dist_blocks) = rdist(@ARGV);

rsync(@ARGV)

perl -MFile::RdistByRsync -e rsync(qw/rdist command flags/)

File::RdistByRsync parses and understands rdist distfiles and command lines.
It can share its understanding by returning what it got (parse_rdist() and rdist()) or it can attempt to emulate rdist using rsync.

Why?

Well, because rdist is so slow its unusable and rsync has such a limited interface that its unusable. Im sure a better specification language than rdists could be developed, but rdists language already exists so I used it to drive rsync.

Rsync::Config::Module is a module entry from a rsync configuration file.

Rsync::Config::Module is used to create a module who can be later used in generating a rsync configuration file. Each module is made by atoms (Rsync::Config::Atom).

SYNOPSIS

use Rsync::Config::Module;

sub main {
my $mod_cpan;

$mod_cpan = new Rsync::Config::Module(name => cpan);

$mod_cpan->add_atom(name => path, value => /var/ftp/pub/mirrors/ftp.cpan.org/);
$mod_cpan->add_atom(name => comment, value => CPAN mirror);
}

SUBROUTINES/METHODS

new(%opt)

The class contructor. %opt must contain at least a key named name with the name of the module.

add_blank()

Adds a blank atom to this module. Returns the object. This method internally calles Rsync::Config::Atom constructor.

add_comment($comment)

Adds a comment atom to this module. Returns the object. This method internally calles Rsync::Config::Atom constructor with $comment parameter. Please read Rsync::Config::Atom contructor documentation to see if any exceptions are throwned.

add_atom($name, $value)

Adds a new atom to this module. This method internally calles Rsync::Config::Atom constructor with $name and $value parameters. Please read Rsync::Config::Atom contructor documentation to see if any exceptions are throwned.

add_atom_obj($atom_obj)

Adds a previsiously created atom object to the list of current atoms. If $atom_obj is not a instance of Rsync::Config::Atom REX::Param::Invalid exception is throwned.

atoms_no()

Returns the number of current atoms.

atoms()

In scalar context returns a array reference to the list of current atoms. In array content returns a array of current atoms.

to_string()

Returns the string representation of the current module. If indent is true, a best of effort is made to indent the module.

indent_step

my $current_indent_step = $module->indent_step;
$module->indent_step(2);

Both accessor and mutator, indent_step can be used to get the current indentation level step or to change it.

name

Both accessor and mutator, name can be used to get the name of the module or change it.

Rsync::Config::Renderer is a Perl module for rsync config rendering.

SYNOPSIS

use Rsync::Config::Renderer;
my $renderer = Rsync::Config::Renderer->new(
indent => 1, indent_char => "t" );
print $renderer->indent_string, q{foobar};
# prints: " foobar";

$renderer->indent(4)->indent_char(q{.});
print $renderer->indent_string, q{foobar};
# prints: "....foobar";

print $renderer->render( foobar, 22, baz );
# prints:
# ....foobar
# ....22
# ....baz
