Yep, this is right, usually snapshots to venti take place every night
so you can only write (or change) a bit less than 6Gb of data per day but
you can store 20Gb in total. The 20Gb are compressed and all duplicate
blocks are merged so that 20Gb goes a long way. If you are dumping large
amounts of data into venti - copying old backup CDs into venti to make them
online, then you can do a snapshot to venti manually to flush out fossil
and free some space in it.
Fossil and venti have served me well and been very reliable - failing disks
are less good but there is a proceedure for recovery.
