I'm interested to hear from members about how often you backup your complete site. Is this hourly, daily, weekly, etc? What is your logic behind your current backup configuration? Do you store your backups off-site or simply on the same server/account? Do you use items such as rsync, rdiff, rsnapshot, r1soft, cpRemote, something else? What do you believe is an acceptable price for a backup service, such as per GB (example: 50GB for $10)?
