[rrd-users] rrd + zfs compression = massive space savings

[Tntteam]

Hey,,

"
note that the gain will drop as your rrd files are filling with
actual data ... so make sure you have plenty of free space on that
system !
"


So when the rrd"s are full, the gain of space will be like how many % ? Any
idea ?


Thanks
