If you want to join multiple devices with a per-file granularity (so

the FUSE filesystem called mhddfs; I wrote an article about it some

Thank you very much for this excellent recommendation. I had never heard
of this layered "filesystem" before. And I have to admit, I was
initially quite skeptical of your mhddfs recommendation, because of...
well... FUSE :-)
But I read your article and the mhddfs documentation and it is exactly
the solution I had in mind (where trouble on one of the disks does never
ever affect data on other disks). mhddfs performance is also great,
130MB/s at only 50% load on one of the cpu's cores - it does only seem
to be limited by the disk and not by the CPU or FUSE.
Thanks again. I will now use mhddfs for my backups. And even though I'm
now not using btrfs for my backups, having a perfectly working backup
solution will make it much more likely for me to use BTFS on my main
disk array once the btrfs RAID5/6 support is slightly more complete :-)
Thanks again,
Gerald
