Subject: Re: [Networker] recommendation to backup 1.5 million small files?
yes,
that's
1
one
directory.
It
takes
days
to
backup,
even
3
million
files
takes
30+
hours
to
backup.
I
know
it's
the
worst
way
to
organise
data
but
it
was
given
to
us
by
a
external
programmer.
so
is
there
a
way
using
legato
to
bypass
the
filesystem
layer
?
