Almost the same here.

Then you even have one reason less for not making incremental backups.
In your case it's almost free storage-wise. The nice thing about
rsnapshot is that you get a complete tree of your backed-up directories
for all increments. This is done using hard links, so it uses very
little space.

It might be enough, but as soon as you need more than a one-liner for
backups in your crontab, I suggest moving to rsnapshot. Don't start
scripting your own backup solution. (It should be mentioned, though,
that rsnapshot supports custom scripts to collect the files to be backed
up. This is useful for databases and other files which you don't want to
copy verbatim while the system is running.)

I wish I could do more to put the sparkle back into my marriage.
