It seems like a great solution, but I don't think I can put into production a possibly stale project without a significant user base. Have you tried it? I perform SMB consulting and when a Linux solution fits the client's needs, I always go with Linux. But increasingly, I can't justify Linux file servers. I've written some cron scripts that take and release lvm snapshots on a schedule, but compared to the Volume Shadow Copy of NTFS that Microsoft released in 2003, it's just cumbersome and basic. We're approaching 8 years without a comparable response. I'm just rather shocked when thinking about it.
