[rrd-users] RRA's for a Month

I do something very similar to this with MRTG and Routers2 using the rrd-archive utility (only really useful for MRTG/RRD so probably not for you).

I'm also working on a patch to rrdtool 1.4.4-trunk  that allows rrdcached to be 'quiesced' temporarily --send it a pause command and a subsequent unpause -- for backup/archive purposes.  Its working in test at the moment but I've not pushed it into prod here or submitted the patch to Tobi yet.

Not a bad idea!  Do you know how rrdcache would handle copying a rrd
file while it's running.  What if say a update is happening on that file
when the copy command is issued.  I know i could stop rrdcache but i
could be copying 10000 files and thats a good amount of time the
rrdcache daemon would be down.
