Re: [gentoo-user] What can I use for a compressed file system?

[William Kenworthy]

I already use reiserfs with notail, but potentially 60G wont go into 40G
of space without compression, and then there is trying to keep
versions ...  Its notail is also irrelevant if you backup into a single
file.  Same for LVM snapshots (though in this case its a non-LVM laptop
that I want disaster protection for - i.e., in case I drop it!).  My
working data is actually handled well by unison onto a solaris system at
work, but again, space/time and data transfer costs are a problem when
trying to do whole systems remotely, so it would be nice to handle it
myself, I just dont want to go buy another disk to do it unless I have
to.
