Why use a 3 Tier Backup System?
We all know backups are important, if shit can happen, shit will happen, they are important both online and offline, but if you are hosting a site or several sites, its important to have a backup strategy, that's why S2R created the 3 Tier Backup System (sounds way more exciting than what it is):
1) Hosting Provider Backup System
- Choose a hosting provider that makes backups, having RAID and high availability and failover hardware, that's all cool for performance and redundancy, but backups should be expected and not on the same hardware as the server (offsite or high end backup software is a plus), having backups from your host eases most problems and makes most disasters easier to handle, as such this is the first backup tier.
2) Offsite Backup System
- Have a cheap vps or backup account from another hosting provider (if he also provides backups that's a plus), then use your hosting panel or rsync or whatever backup system you prefer to use to make and transfer backups to this box, we normally choose a weekly schedule for this (running on weekends when traffic is low), there is no need for daily copies, cause the goal is to have a weekly clean backup, of course we store 3 backups, so 3 weekly backups are always available on the server, the idea is to use this encase your hosting provider goes bankrupt or closes your account for some reason (nowadays its more likely than you think), and you get cut off from your first tier backups, so therefore this is the second tier backups.
3) Local Backup System
- This one is also easy to understand its a local backup of the accounts, in my case its to my custom made backup system (2TB mirrored to another 2TB, way more than enough for my sites and personal files + Mozy Backup of all of this), similar to RAID, this is done also weekly (could be done only monthly), this is done for the simple reason of peace of mind and safety, i never needed it, but there is no such thing as too many backups and having one locally guarantees that whatever happens to your sites they will always be able to comeback from any disaster, so this is the final third backup tier.
