It is a fact of life - even the best hardware can fail. Backups can be performed on a daily or weekly basis and are stored onsite. You do not need to buy any special equipment or backup tapes. We use a multi processor IBM pSeries 620 server with 1 GB RAM and LTO Ultrium 3583 Scalable Tape Library for fast backup and recovery. The backup hardware is stored in a separate secure area of our data center.
Access is limited to the system administrators only.
Backup network traffic, which normally amounts to a few GB per month, may incur additional bandwidth costs if you are at the limit of your bandwidth allocation. To recover from hardware failures. To restore old CGI scripts when improvements backfire. To mitigate hackers attacks and restore affected sites. Secure, physically separate, storage on site.
