I'm looking for a script that can do some pretty extensive backups... If someone is willing to help me with anything regarding this, please do! I'm pretty sure it's not a matter of not looking hard enough. I don't know if this exists. I'm looking for the following functions:

• Backup of selected, or all MySQL databases.
• Full backup of all site subdirectories and files.
• (optional) All the files compressed in a zip or gzip archive
• The compressed archive, or all the files, FTPed to a remote server.

Is there anything out there that can do this? I will be hosting a site on free hosting, and I would like this script to do the backup, and FTP it all to an FTP server I have access to. Well? Is this possible? Can someone find or write a script that can do this? I need one preferrably in PHP (MySQL is on the free hosting server, like I said, so that's not a problem). I don't know if the zlib will be installed on the free hosting server, but I can ask. I'd appriciate any help with this. Thanks!
