Jeremy Zawodny’s blog post from early last month has prompted me to look at offsite backup solutions again. Currently I am backing up all my websites, from various servers and accounts, to my home server using rsnapshot, running at 4am every morning. So far so good, and I loves the flexibility of rsnapshot. I guess if one of my server dies, it would be trivial re-populating another server, moving the DNS records, and start serving again.
Moreover, the cost of running a home server is in fact less than what Jeremy has calculated. My home server (a 1Ghz Duron + 3 smaller disks) uses less juice, but more importantly, it needs to be running anyway regardless whether I am using it to perform backups or not, as it also provides a few other services. Like, acting as a file server for my home network.
