So I've learned a valuable RAID 0 lesson, and it fortunately was not a major catastrophy. I got lucky, and had a workable-enough backup on tape to make the user who needed some data happy. Now, from the OS side, LVM is an option. Say the RAID controller only allows hardware striping or mirroring for logical volumes, but I want to use more than two disks, and I don't want the...

...rom a ZFS volume gives you even more trouble, and it is rather noticeable that ZFS wasn?t designed with performance in mind. That doesn?t even mention features like checksumming, deduplication, compression and the creation of subvolumes (or their equivalent). It also doesn?t mention that LVM is a catastrophy. I could use hardware RAID, but neither XFS, nor ext4 offer the required features. So what should I use instead of btrfs or ZFS? I went with btrfs because it?s less troublesome than ZFS and provides features for which I don?t know any good alternative. So far, it?s working fine, but I?d rather...

I''m looking for a way to backup my entire system, the rpool zfs pool to an external HDD so that it can be recovered in full if the internal HDD fails. Previously with Solaris 10 using UFS I would use ufsdump and ufsrestore, which worked so well, I was very confident with it. Now ZFS doesn''t have an exact replacement of this so I need to find a best practice to replace it.

Changing the subject since this is rather Btrfs specific now.
