Filesystem Snapshots... Do any filesystems have them?



I was wondering as we were discussing cloning and whatnot in the other
thread about using dd and such, are there actually any filesystems
available for Linux that make use of FS snapshots?

I know that LVM seems to have this capability, but is there anything on
just a filesystem level (similar to FreeBSD's mechanism with UFS2) that
anybody is aware of?

Just curious,
Mike
