Just to be clear, fossil stores the whole file if it differs from venti not just a diff. Venti however compresses data and factors out duplicate blocks from all files so is very space efficent. Fossil can also store its own snapshots but these are not compressed and are usually reclaimed after a day or two. I use this to take a fossil snapshot every 15 mins which is kept for 3 days and venti snapshot taken every night which is kept forever. > How much hassle is it to mount venti on a different (secondary) partition? > In that case, how much trouble have I to go through to simply set up venti > on that partition and start using it, without having to re-install and > -format everything? Plan9 filesystems (on the PC) always live inside a primary DOS partition, however this may then divided into several plan9 sub-partitions. I don't believe you can put plan9 partitions inside a secondary DOS partition. -Steve
