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.
