That gives tedious manual work.. and btw, won't save you if you from
loosing stuff from when the backup was made until now.

Again lots of manual work.. I actually have a DAT-station.. but I'm not
getting it used. People have DVD-burners, but many don't get time to do
a backup anyway. A Copy-On-Write feature in the filesystem would save
the average dataloss situation todag (for home users). Where they
accidentally deletes stuff.

> Streamload.

Why, when it could be quick and transparent. And Linux is used many
places where you cant let data out-of-the-house of where bandwidth
"sucks". The waste-space in my diskdrives increases everyday .. and i
fill up with a tar-ball of the system every now-and-then, but it would
definately be better suited and more effecient (save me more times) done
directly in the filesystem.

Thats called raid, we have that allready. But raid won't help for and:
rm /etc/passwd, a Copy-On-Write filesystem (not-snapshot) would. Used on
a mirrored raiddisk, with enough space on the disk, it would actually
guard you from allmost anything but getting the computer stolen.

Totally unrelated to reiser4 but a feature that would be nice to have in
"any" filesystem.
