The size of my db is more then 50GB , so I consider that the pg_dump
is not a good backup tool for me.
And, sometimes, I need query data which is some days ago ( between 1 ~
14 days ).
If I want to transfer my db to different PG version, I will use slony-I. :)
I worried that mksnap_ffs spend much time on making a new snapshot.
I don't know whether PG work very well during the period of making snapshot.
Or the snapshot be made successfully when the PG execute / commit sql
statments continuously.

Could I use mksnap_ffs under freebsd to make
