I have a backup script which backups up all files for a website to a zip file (using a script similar to the answer to this question). However, for large sites the script times out before it can complete.
Is there any way I can extend the length of time available for the script to run? The websites run on shared Windows servers, so I don’t have access to the php.ini file.
Simply put; don’t make a HTTP request to start the PHP script. The boundaries you’re experiencing are set because you’re using a HTTP request, which means you can have a time-out. A better solution would be to implement this using a “cronjob“, or what Microsoft calls “Scheduled tasks“. Most hosting providers will allow you to run such a task at set times. By calling the script from command line, you don’t have to worry about the time-outs any more, but you’re still at risk of running into memory issues.
If you have a decent hosting provider though, why doesn’t it provide daily backups to start with? 🙂
