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 (\0).
              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.
