NAME

       rdiff-backup-statistics - summarize rdiff-backup statistics files

SYNOPSIS

       rdiff-backup-statistics [--begin-time time] [--end-time time] [--minimum-ratio ratio] [--null-separator] [--quiet] repository

DESCRIPTION

       rdiff-backup-statistics	reads the matching statistics files in a backup repository made by rdiff-backup and prints some summary statistics
       to the screen.  It does not alter the repository in any way.

       The required argument is the pathname of the root of an rdiff-backup repository.  For instance, if you ran "rdiff-backup in out", you could
       later run "rdiff-backup-statistics out".

       The  output  has  two  parts.  The first is simply an average of the all matching session_statistics files.  The meaning of these fields is
       explained in the FAQ included in the package, and also at http://rdiff-backup.nongnu.org/FAQ.html#statistics.

       The second section lists some particularly significant files (including directories).  These files are either contain a lot of  data,  take
       up increment space, or contain a lot of changed files.  All the files that are above the minimum ratio (default 5%) will be listed.

       If  a  file  or directory is listed, its contributions are subtracted from its parent.  That is why the percentage listed after a directory
       can be larger than the percentage of its parent.  Without this, the root directory would always be the largest, and  the  output  would	be
       boring.

OPTIONS

       --begin-time time
	      Do  not  read  statistics  files older than time.  By default, all statistics files will be read.  time should be in the same format
	      taken by --restore-as-of.  (See TIME FORMATS in the rdiff-backup man page for details.)

       --end-time time
	      Like --begin-time but exclude statistics files later than time.

       --minimum-ratio ratio
	      Print all directories contributing more than the given ratio to the total.  The default value is .05, or 5 percent.

       --null-separator
	      Specify that the lines of the file_statistics file are separated by nulls ().  The default is to assume  that  newlines  separate.
	      Use this switch if rdiff-backup was run with the --null-separator when making the given repository.

       --quiet
	      Suppress printing of the "Processing statistics from session..."	output lines.

BUGS

       When aggregating multiple statistics files, some directories above (but close to) the minimum ratio may not be displayed.  For this reason,
       you may want to set the minimum-ratio lower than need.

NAME

       librsync - library for delta compression of streams

SYNOPSYS

	#include <stdio.h>
	#include <stdlib.h>
	#include <librsync.h>

	cc ... -lrsync

DESCRIPTION

       The  librsync library implements network delta-compression of streams and files.  The algorithm is similar to that used in the rsync(1) and
       xdelta(2) programs, but specialized for transfer of arbitrary-length octet streams.  Unlike most diff programs, librsync does  not  require
       access to both of the files on the same machine, but rather only a short ``signature'' of the old file and the complete contents of the new
       file.

       The canonical use of librsync is in the rproxy(8) reference implementation of the rsync proposed extension to HTTP.  It may  be	useful	to
       other  programs which wish to do delta-compression in HTTP, or within their own protocol.  There are HTTP-specific utility functions within
       librsync, but they need not be used.

       A number of tools such as rdiff(1) provide command-line and scriptable access to rsync functions.

BUGS

       The rsync protocol is still evolving.  There may be bugs in the implementation.	The interface may change in the future, but it is becoming
       more stable.

       Many  routines  will panic in case of error rather than returning an error code to the caller.  Patches to fix this are welcome, but at the
       current state of development aborting seems as useful as trusting to possibly-incomplete checking in the client.
