SourceForge makes a .tar.gz of each project's complete CVS repository each night. Project admins can access the download from the admin page. Only the most recent tarball is available at SF, so some project admins keep multiple ones on their own servers. The nightly tarball is currently about 12MB. I imagine that someone has written a short script to download the files automatically, but I haven't looked for one. I don't know what AOL does for backup, if anything, but I'll try to remember to ask at the next chat. I also want them to start using the syncmail scripts so that developers will get notices after commits. According to the SourceForge documentation, SF makes backups in case of hardware failure, but won't help if the problem is your fault.
