rsnapshot is actually smart to handle this situation.  What it will do
is copy hourly.0 to hourly.1.  If you can't connect to the server, it
just assumes that the last good one is the one you stick with.

I run mine every 2 hours during daylight hours (hourly is just a name).
The daily/weekly/monthly run at a time when I expect the computer to
actually be one.  Here's my crontab entries:

50 10,12,14,16,18,20 * * *    root rsnapshot -q hourly
30 9 * * *      root rsnapshot -q daily
50 9 * * sun    root rsnapshot -q weekly
10 10 1 * *     root rsnapshot -q monthly

My intervals in rsnapshot.conf are as follows:
interval        hourly  6
interval        daily   7
interval        weekly  4
interval        monthly 3

Also, rsnapshot handles the daily and weekly backups properly too.  The
daily is just the oldest hourly from yesterday - the snapshots just
rotated through.  I've got many "copies" of my data using very little
disk.  It just runs by itself and I don't have to babysit it.
Occasionally rsync will spit out an error from files that are deleted in
progress (usually mail temp files) and I just delete those messages.
