I manage a handful of web services spread across multiple shared hosting accounts and VPSes. I do manual backups on an occasional basis, but the process of backing up all of the web content combined with databases and, in the case of the VPSes, settings and config files, is very tedious and exactly the sort of thing that should be automated.I've been working on and off on a batch file to automate the FTP backups / database dumps, but I'm curious how everyone else manages offsite backups. Are there any clear market leaders in server-backups-as-a-service, or any open source software that already does this well?
