You dont say what you are doing with these files except 'storing' them. I=

The packing rate needs to depend on the rate at which old object revision=
s=20
expire. That is, the rate at which objects are deleted, plus the rate at=20
which existing objects change.

If you only ever *add* these huge files, then daily packing will gain lit=
tle.=20

(Independant of the packing frequency, packing regularly via cron is alwa=
ys a=20
good thing)

Are there any production quality non-undoing storages?
