However, if the OP wants to keep that data for min 5 months, at 1 
minute resolution, then that's a lot of samples. If, as is hinted, 
changes are infrequent, then that's a very inefficient way of storing 
them - ie there are other tools that would be more appropriate for 

RRD will certainly store his other (scalar) data though.
