I like write-anywhere/COW filesystems.
Unfortunately the open source ones kinda blow due to interesting performance penalties (I'm looking at you, btrfs back ref management) or crazy memory usage/non-extent based systems/read-modify-write induced mania (I'm looking at you, ZFS block tree)
- mcpherrinm 14y agoWhat non-open source ones do you like, then?
- sliverstorm 14y agoOh, you've probably never heard of them.
- zanny 14y agoI've been playing with btrfs under the 3.7 prerelease kernel on an arch kvm with a virtio disks, and with lzo compression btrfs is kicking some serious read / write butt vs every other major filesystem I can think of. Given sufficient hardware, of course. Haven't tried it on an ssd though, only on 7200rpm turnstables.
