[SOLVED] Filesystem suggestions

acid_kewpie · 07-18-2011, 11:57 AM

yes, latest is one thing, or "since before I did that upgrade" but your example of 1 week, 1 month, 3 months etc, suggests a level of structure and reliance you would expect form a backup system. I would have full confidence is going back to a tape containing a full system backup from 12 months ago. I would *NOT* have confidence in expecting a 12 month old snapshot to still exist.

Again, backing up to tape is *massively* wasteful, but the benefits far outweigh the negatives.

Roger that!

So, btrfs or native zfs?

See https://secure.wikimedia.org/wikiped...wiki/ZFS#Linux for zfs on Linux; note the 2 versions: zfs-fuse, native kernel zfs.
btrfs https://secure.wikimedia.org/wikipedia/en/wiki/Btrfs

zfs is rock solid on Solaris (because they built it yrs ago).

zfs-fuse is ok but a userland FS, not in the kernel.
native zfs is a kernel module, but you'd have to get it from them, not from any distros right now I believe, due to License issue as stated.

BTRFS is still under heavy development https://btrfs.wiki.kernel.org/index.php/Main_Page

You'd have to research the options quite a bit I feel.

I found another alternative as well: the debian port kFreeBSD. Linux userland + bsd kernel. This means stable zfs on Linux. Yay!

However, there is no sun java for the port. :-( *sigh* the backup solution I was planning to use requires sun java 1.6

Back to the drawing board I guess...
