Atomic creation doesn't solve the problem of timestamps being too coarse grained to distinguish between a time just before and a time just after the snapshot was created. -- Colin Percival Security Officer Emeritus, FreeBSD | The power to serve Founder, Tarsnap | www.tarsnap.com | Online backups for the truly paranoid
