Several server configuration

Hello, I need to modify some configuration in my server: BACKUP I want to have a backup of everything set up as daily, in a new volume inside the server. The backup must remember the last 14 days. It's required to install this virtual new volumen in this amazon server. STAGE SERVER We want to have a second virtual server as "stage" and tests system. In this server there must be a copy of CTD web and [login to view URL] web, set up via the Subversion system installed in the machine. SFTP I need the main username to be accesible via .pem file but also with username/password from any computer via sFTP (FTP must remain unavailable). This main user must be able to see every folder in server via sFTP. I also require documentation of how to create new sFTP users, how to change their passwords and how to delete them. WEBDAV We want to change the path of it to [login to view URL], and point it to /var/webdav We need a username to access it with password and not with .pem file, and the documentation about how to change username/pass. [login to view URL] We need you to point this domain to this same server and we need a stage version in the new stage server. We also need to know how to create sFTP users to access to this domain, documented. REDMINE Email notifications doesn't work. We need to fix it and work when sending notificacions to @[login to view URL] emails (googleapps) and also to other domain mailboxes. POSTFIX Every email account is used by Google Apps, so we don't want emails to arrive to this server and stay stored neither. We need them to be forwarded to jc@ctd.io. We need that every email sent from this server appears as sent by jc@[login to view URL], and we need that it works when sending to gmail, yahoo and hotmail email. It'll requiere to set up the needed certificates. if you check the mail log, it fails when sending to jc@[login to view URL] PHPMYADMIN We want it to has a different url, this: [login to view URL] DOCUMENTATION Everything said as "documentation" in this brief must be delivered as a PDF at the end of the tasks. Thanks jc
