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

SYNOPSIS
       rdiff-backup-statistics  [--begin-time time] [--end-time time] [--mini-
       mum-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 for-
              mat 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 (\0).  The default is to assume that newlines separate.
              Use  this switch if rdiff-backup was run with the --null-separa-
              tor 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.
