Here's a patch which addresses a very old itch of mine:
I wanted just one invocation to get the backup
and all necessary rotations in one go.
This is useful for desktops and laptops,
which do not run 24x7 and frequently miss rotations otherwise.
I solved the same problem using a wrapper script and wrote 9/1/2010 12:09:
do-rsnapshots: intelligent and fully automatic management for the rsnapshot
folders hourly daily weekly monthly yearly
I use rsnapshot since 2006 with Suse Linux at my desktop and are very happy
to have it..
Many thanks to the developers.
Since 2010 I have a laptop with Suse Linux 11.2 use rsnapshot-1.3.1.
I have in rsnapshot.conf
interval hourly 8
interval daily 7
interval weekly 4
interval monthly 12
interval yearly 100
because I want to hold on my old data.
In the crontab should be
0 * * * * /usr/bin/rsnapshot hourly
50 23 * * * /usr/bin/rsnapshot daily
40 23 * * 6 /usr/bin/rsnapshot weekly
30 23 1 * * /usr/bin/rsnapshot monthly
20 23 1 1 * /usr/bin/rsnapshot yearly
Since the laptop is not always running, its very unsure when the daily
weekly monthly and yearly backups are made.
If it is not running after 23:00, there is no rsnapshot daily weekly monthly
oder yearly.
Therefore I wrote do-rsnapshots, that calls rsnapshot as needed.
In the crontab now is only
0 * * * * /usr/bin/do-rsnapshots
do-rsnapshots first reads the rsnapshot configuration file and then knows
how many updates should be there for each of daily weekly monthly or
yearly.
Then it looks for the last monthly folder. If it exists, it looks for
yearly.0. If that does not exist or is not made in the same year as the
oldest monthly folder, rsnapshot yearly is called with all options from the
command line of do-rsnapshots.
The same is done with monthly weekly and daily.
At last it calls (rsnapshot sync if activated and) rsnapshot hourly with all
options from the command line of do-rsnapshots.
So the backup folders are automatically build and managed.
Since all the actual work is done by rsnapshot, I hope, there are no new
bugs (exception see below).
It is also possible, to do different things.
If you want to have one daily update for a whole year (huh
and then only
the yearly ones, you ought to have in rsnapshot.conf
interval daily 366
interval yearly 100
it all goes automatically with
0 14 * * * /usr/bin/do-rsnapshots
in crontab. But I didn't test that.

REQUIREMENTS:
You have to use only some of the the known interval names hourly, daily,
weekly, monthly and yearly.
Of course the bash has to be installed, also grep and the coreutils for cat
and cut.
KNOWN BUGS
I didn't implement the args in man rsnapshot
