One of the major selling points was the ability to take filesystem snapshots in order to make backups from a consistent filesystem on such a high-traffic system. Unfortunately, when I take a snapshot, performance slows to a crawl - to the point where the system stops responding to network requests (ping, SMTP, etc.). Also, the snapshot takes 10-15 minutes to complete. Is this a typical situation? Will I need to schedule downtime for backups in spite of this nifty new feature? Am I doing something wrong? Could use some advice.
