I am receiving errors on our website when customer tries to purchase a product. We believe this is an issue related to a HTTPS canonicalization issue. Our previous server expert solved this same exact issue on year ago. These were his notes: "your server has CentOS 5.9 installed, so it doesn't support SNI, so there was a subdomain mess. I've just had to make some changes to webserver configuration so solve the issue" We are seeking professionals with server-side development experience who can help us with this issue. We also have some future ongoing back-end and front-end work in the future that we can give to you if you can help us out.

Amazon S3 Backup Script We have a Linux server that uses Cent OS and we are looking to backup the server to Amazon S3 . We would like to have a script that does the following: - Backup to Amazon S3 only the changed files every day in certain directories Amazon has a Glacier component that is cheaper, so maybe once every 3-4 weeks, create a folder there with the date, and then copy over all files there. So this will mean every 3-4 weeks, we are taking a full backup and just moving it to the special section of Amazon that does not cost us much. -Making sure we keep the permission of the file structure when we backup. -Take a mysql dump of the databases everyday -Move the mysql database dump to the regular section also. Also, move the database off to the special Glacier section after it is in the normal section for 1 month -Included with this is showing us how you script installs and writing instructions for us to install on a new server and then helping us install on another server -Giving us complete details on how to use and do a restore -Anything else you think can help us setup a good backup plan for a Linux server on Amazon S3
