NAME

       rsnapshot-diff - a utility for comparing the disk usage of two snapshots taken by rsnapshot

SYNOPSIS

       rsnapshot-diff [-h|vVi] dir1 dir2

DESCRIPTION

       rsnapshot-diff is a companion utility for rsnapshot, which traverses two parallel directory structures
       and calculates the difference between them.  By default it is silent apart from displaying summary
       information at the end, but it can be made more verbose.

       In the summary, "added" files may very well include files which at first glance also appear at the same
       place in the older directory structure.  However, because the files differ in some respect, they are
       different files.  They have a different inode number.  Consequently if you use -v most of its output may
       appear to be pairs of files with the same name being removed and added.

OPTIONS

       -h (help)
           Displays help information

       -H (human)
           Display  more  human-friendly  numbers - as well as showing the number of bytes changed, also show MB
           and GB.

       -i (ignore)
           If verbosity is turned on, -i suppresses information about symlinks, directories, and special files.

       -s (show size)
           Show the size of each changed file after the + or - sign.  To sort the files by decreasing size,  use
           this option and run the output through "sort -k 2 -rn".

       -v (verbose)
           Be verbose.  This will spit out a list of all changes as they are encountered, apart from symlink, as
           well as the summary at the end.

       -V (more verbose)
           Be more verbose - as well as listing changed files, unchanged files and symlinks will be listed too.

       dir1 and dir2
           These  are  the  only  compulsory  parameters, and should be the names of two directories to compare.
           Their order doesn't matter, rsnapshot-diff will always compare the younger to  the  older,  so  files
           that  appear only in the older will be reported as having been removed, and files that appear only in
           the younger will be reported as having been added.
