It's a pity that:
# min hour day-of-month month day-of-week command
30    3    */28         *     *           rsnapshot-script...
won't work -- I take it that would just fire on the 28th of every
month?
I think you may have to write a script that can tell when it is the
correct day.
e.g.:
SHELL=/bin/bash
# min hour day-of-month month day-of-week command
30    3    *            *     *           [ $(( $(date +%j) % 28 )) eq 0 ] && rsnapshot-script...
%j says that date should print the day number of the year, so
modulus 28 and only execute when that's 0.
Cheers,
Andy
