Are there any production ready Log File Systems out there for linux yet?
The most promising looks to be the NILFS, but it looks to be still in the
preproduction stage. I am looking for a reliable system for production
server. Have any of you tried NILFS or implemented it in a file server, and
what were the results?

Thank you for the help,

Hi. Can't help you, sorry.

But what i a Log File System? On that retains version of files, or perhaps
one the logs the modificaions to files, so you can 'rewind' and re-apply.
Banks seem to do that, I've heard.

I am setting up a file server and I was shooting for both, redundancy
with raid1 and archiving with LFS. Yes, LFS let's you look incrementally
at all the changes to a given file, thus if someone ****s up and changes
something in a file and then saves it, using LFS you can get the prior
copy of the file back. And it's more efficient the other archiving
solutions because it only saves incremental changes, thus if you have
100mb file that has been changed slightly 10 times, you can have access
to all 10 prior copies of that file without wasting 1gb of space on it.
