php automatic backup via ftp from host to remote server

NOTE: PLEASE DO NOT BID IF YOU DO NOT HAVE EXPERIENCE IN THIS, 0 RATING OR LESS THAN 9 FEEDBACK THANK YOU! I am hosting several sites on the rackspace cloud - cloud sites and have a remote backup server with bq internet. There is no ssh access for rackspace. I would like to have a script run via cron to backup all my sites via ftp. The sites should be zipped to save bandwidth and space, then moved. In addition to this, I would like only modified/new files to be saved, though a full backup would be nice every month or so. The modified/new files should be backed up at 6am, 12 noon and 6pm. Old backups should be deleted every 3 months. ## Deliverables 1) Signup, contact, search, login and other forms might send info to the client. Never use anything other than the email address we provide you with and a fake name like 'Joe Test' to test the system. No contact should ever be made with our client. If we have not set you up an email address, and you need to test, then just ask. 2) Never use existing code or photography unless provided by or approved by us. 3) Source code should be documented, but no mention of your name, company should ever be used. Everything whether code or testing text must be professional and in English. No language other than English is to ever be used. 4) Clearly document how all items were completed. In addition, give descript details on what is needed to do to upload the changes/modifications to another server. Upload all source files as well. 5) Document everything in the project manager. At least one update every 24 hours is required. Your most updated work is to be uploaded to the server at least once every 24 hours as well. 6) Backup the files before you work on them, and save the files you worked on in a backup folder on the server, before any modifications were made. It must be very easy to revert back, if needed. 7) Triple Check everything for flawlessness and cross-browser compatibility. A project should never be delivered with any flaws at all! 8) No work done for us is to ever show up in your portfolio, or anywhere else. Our traffic logs show where they are linked â?'?“ and no traces should be sent tfrom you! 9) Deadlines are to be met - this means FLAWLESS work is to be presented before the deadline. ## Platform rackspace cloud sites. would like this done using php
