Q:

rsnapshot diff between snapshots

I am using rsnapshot to manage incremental backups of some GNU/Linux servers. 
Although rsnapshot is delivered with a tool called rsnapshot-diff it just provide disk space statistics. 
The question is how to get a diff: new and deleted files, on a specific snapshot. 
I read suggestions like
# find /raid/rap/$interval -type f -links 1 -exec du -k {} \; | sort -rn

but it didn't work on my snapshots.  I did modify a single file an run the one liner above right after a new hourly.0 snapshot and no differences were reported.  Alhtough if I run it as
# find /raid/rap/$interval -type f -links 2 -exec du -k {} \; | sort -rn

the modified file is reported.  Why there are two links to the modified file? 

A:

Not sure if this question has been answered, but just wanted to do the same thing.  I used:
rsnapshot-diff -v folder1 folder2

which worked for me.  Note that folder1 and folder2 are folders and not snapshot names.  In my case, folder1 was /USB/USB_HDD_7/Snapshots/daily.0
