Hi folks,
is anyone working on an compressed filesystem ?
I'm currently using fuse-compress (on Linux) for an compressed
backup storage (done via rsync). But it's a bit too unstable
and doesn't help much on small files.

Hi folks,
is there already an compressed (9p-)filesystem ?
I'm doing regular rsync backups of several machines and like to
save disk space. Performance is not important here.

hello
venti compress the blocks it stores iirc, so if you put the data into
a fossil which dumps to a venti server, you will be compressing the
data.

hmm. I need someting that can run on Linux (ie npfs or libmixp based).
I'm currently playing around with some FUSE based filesystems,
but I'm not actually satisfied.

hello
venti works on linux with plan9ports, take a look at the plan9ports
manual pages.
slds.

vacfs, the venti-backed file server is read-only. Not sure if that's
what Enrico needs.
Thanks,

Venti compresses data as the archive back-end to Fossil. That would
meet your requirements pretty closely, I think.

What are you backing up? /home or /usr or /usr/local or ....
depending on what you are backing up, venti may be a huge win, as
duplicate blocks from different machines will result in only one block
being written.
What is "several" -- 2 or 3 or ...
What's the disk space issue? how much disk?
