The File::Rsync::Mirror::Recent modules are constructed around the idea. There's a little program I use to sanity-check whether the roll-over times are following the plan that is made up for them: % rrr-overview /home/ftp/pub/PAUSE/authors/RECENT-1h.yaml Ival Cnt Max Min Span Util Cloud 1h 57 1285609921.43 1285606962.91 2958.53 82.2% ^ ^ 6h 230 1285609921.43 1285589306.26 20615.18 95.4% ^ ^ 1d 411 1285609321.88 1285525747.73 83574.15 96.7% ^ ^ 1W 2074 1285602058.99 1284997293.30 604765.70 100.0% ^ ^ 1M 7614 1285602058.99 1283010164.75 2591894.24 100.0% ^ ^ 1Q 19780 1285339261.48 1277566019.09 7773242.38 100.0% ^ ^ 1Y 97275 1283500141.57 1251943652.99 31556488.58 100.0% ^ ^ Z 158266 1277368802.31 0.12 1277368802.19 - ^ ^ The ascii art in the last column displays how the time intervals overlap. -- andreas
