What do you use for backups to ftp server?
I've tried the setup with Amanda and virtual tapes on the ftp server mounted with Curlftpfs and I'm not satisfied with it. I just don't feel confident about Amanda.
Also I cannot use anything that uses rsync on the ftp mounted filesystem because it only creates the directories and doesn't create files as it cannot execute "mkstemp".
I've been thinking about Bacula but I can't find any good HOWTO for it.
