I wonder if VaultPress is used by most of the bloggers surveyed because when they started blogging, VaultPress was the best premium solution. I have been using BackupBuddy without major issues for about 5 years and it has grown into a very reliable backup solution. Migrating sites is also very easy now.

I like VaultPress as well, but it is costly. Once you get up to about 25 websites, VaultPress would be at least $1500/year whereas a developer license for iThemes (incl. BackupBuddy, Security, etc.) is $150/year. That makes VaultPress 10x more - or am I missing something? Granted, most of the sites I maintain are smaller sites.

I do have trouble with BackupBuddy on GoDaddy hosted sites, but Updraftplus seems to work well there.
