PHP/Perl code to backup web folder

We have a number of Cobalt RAQ servers running Linux, Apache, PHP, perl-mod, ChilliASP, etc. Script requirements: 1. No need to have root level access 2. Password protected - needs to be in clear text so that user can set it to their requirement 3. Backs up into a compressed file (tar/zip/rar/gz) 4. E-mails to a user determined address. Ability to split e-mails if larger than 5MB or other user predetermined setting. 5. When user drops file into the root of their site, they chmod the file, and access the script through [login to view URL] (eg) and are confronted with a password. Once this is entered, they go to the backup settings page - where they check a box to say "back my entire site up", enter the e-mail address they want the compressed file sent to, and click on "submit it" to start the process running. 6. Must be customisable - eg $sendmail = /usr/sbin/sendmail $tar = /bin/tar $gzip = /bin/gzip $httpreferrers = [login to view URL], [login to view URL] ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. 4) Full instructions for users ## Platform Linux, Apache, PHP, Perl, cgi, ASP. ## Deadline information This is a fairly simple project, and as such we would require delivery of the completed product in 24 hrs from bid acceptance.
