You can change this BUT you will need to delete and re-create all your RRDs
which means you will lose all your data.

If you just want higher accuracy and save the high-resolution
measurements for a longer period than 7 days you can set this in your
config.php:
$config['rrd']['rra'] = $config['rrd']['rra_300']['accurate'];
This will save the measurements for 93 days before downsampling it at the
cost of disk space of course and you will still need to delete all your
current RRDs for this to take effect.

If you want to save data for more than 4 years you will need to edit the
RRA-values, this is a bit more complicated and requires you to understand
the RRD format.
You can find the defaults in observium/includes/defaults.inc.php at line 130
You will need to create a new array with your new values and then set that
as $config['rrd']['rra'] and then delete your RRD-files for it to take
effect.
