below is a perl script which i run after each backup -- it shows the
statistics for the most recent session, the average of all sesssions, and
lists any directories which contain more than 4000000 total bytes of new
or increment files. this helps to find which users are causing the most
rdiff-backup traffic.
invoke with: backup-statistics /path/to/mirror
(i.e. the path above rdiff-backup-data)
you'll probably want this patch as well -- otherwise filenames with \n
in them can mess up parsing of the file_statistics*gz files.
both of these are now in http://arctic.org/~dean/rdiff-backup/ ... the
patch is included in the "dg3" patch there with several other one-liners.
