Re: [WebDNA] backup / mirror website & databases

texte = 1797 I'm currently setting up two servers for one of my clients, a main server and a clone that I will call the backup server. They will reside in different data centers, one East Coast, one West. I'll run a WebDNA script via trigger on the backup that flushes dbs on the main, then duplicates the main dbs to a separate folder every hour. Rsync then pulls the main dbs from this folder. If rsync can't connect to the main my script will text me. Then I'll check to see if the main has gone down. If so I'll point my DNS to the backup until the main is online again. Since the main is not expected to go down very often, an hour offline for server switching and DNS propagation doesn't bother my client, especially when I can implement this solution at low cost. The benefit are (1) constant backups in native file format, (2) a backup that's ready to take over for the main 24/7, and (3) a backup that's immune to physical disaster on the main.
