Backups

[Twister]

For a production server with ~ 1 Terabyte of data on it, what would be a good way to backup all that data? What about only a couple hundred Gig?

I am horrible at implimenting backup procedures because I simply never had to before. Could someone point me to some informations, or shed some light on some modern backup techniques?

You need a good definition of your requirements, first off. Just saying `I need 1TB of backups` doesn't cut it. You need to know how tolerant the main server is of faults, how tolerant the organization is of downtime, how much the data changes in, say, an hour, what the security situation is, what laws govern use/distribution/leakage of the data, etc. From this you can tell whether you can just do a nightly tape backup, or if you need something more complex like constant updates to a near-line server that can do failover if need be, then backup off that several times a day and move data offsite in encrypted volumes, whether you can do monthly full backups and daily incrementals, or daily full and hourly incrementals, or whatever else. Trust me, it gets complex very quickly, but in the end it's not that hard. You just need to sit down and think about things one step at a time.
