Re: cloud backup services

At iInTheCloud.com we offer two cloud based backup options.

1- Back up to a local Crossroads SPHiNX VTL which is then replicated 
automatically to our SPHiNX.
	- Advantage is fast backups with a local copy for fast restores.
	- Automatic off-site copy as soon as the backup completes.

2- Use PowerHA or Mimix or MaxAva or ... to replicate data to a 
partition in our cloud. Backups are then done on our system and you have 
no outage whatever.
	- Advantage is data is ALWAYS off site and current there.
	- Advantage is bandwidth is much less as only changes cross the wire 
and they do so all day long as they occur.
	- Disadvantage is a local restore is hard because the backups are with us!

	Nathan's response pointed out one issue with backups to the cloud: 
Bandwidth! You need a bunch in most cases unless you can really figure 
out what to back up each night. Change 1 row in a 500,000,000 row table 
and you get to send the entire table with that night's backup. If you 
were replicating to a remote server or partition ONLY that one change 
goes across so its done instantly.	

	ALSO COnsider that until the ENTIRE backup has been copied off-site you 
got NOTHIN off site. Partial doesn't do you much good. With replication 
you're current off site almost continuously.

	Just some points to ponder.....
