Comment 6 for bug 340671

Maybe that's just because only "hourly" (in your configuration) really backs up files from your "productive" machine/volume, while the "higher" backup levels like "daily" and "weekly" just clone the hard links from the "parent" level (e.g. "daily.0" is a clone of "hourly.0").

See the man page of rsnapshot:

"Intervals must be specified in the config file in order, from most frequent to least frequent. The
first entry is the one which will be synced with the backup points. The subsequent intervals (e.g.,
daily, weekly, etc) simply rotate, with each higher interval pulling from the one below it for its
.0 directory."
