How could I keep this historical data more detailed on Cacti, like the graph from the backbone provider above ???

I don't know wich software they are using, but I beleave we can do the same on Cacti.

Basically, edit your data source profile and add rows to the respective RRA's. Best delete all the RRDfiles, or splice them afterwards.

1) Update the data source profile to new Rows and retention
2) Move old RRDfiles to temp directory
3) Let Cacti recreate the RRDfile with the new setting
4) Learn to use the splice_rrd.php script to merge the two files.
