The time and computation costs are minimal. The main problem you will
run into is that taking a snapshot forcefully pushes out a transaction
group. Normally, ZFS tries to sync transaction groups every 3-5 seconds
in order to group enough data together but not waiting too long to
commit (non-ODSYN

you can find the ZFS on-disk spec at:
http://opensolaris.org/os/community/zfs/docs/ondiskformat0822.pdf
I don't know of any way to produce snapshots at periodic intervals
other than shell scripts (or a cron job), but the creation and deletion
of snapshots at command level is fairly instantaneous
Hi,
I'm interested in the overhead of making, cloning, and destroying snapshots.
It sounds like the cost for all of these is low, but how low??
For example, could I make snapshots of a system every 5 seconds? every second?
More often than that?
I'm primarily interested in the time/computatio
