This proposal outlines Wikimedia UK's requirements for a backup and disaster recovery solution, encompassing the web/email servers and office computers.
Infrastructure
The WMUK infrastructure consists of two main sections:
- Three virtual servers, hosted with Rackspace
- Personal desktops, volunteer laptops and one server, located in the London office
The virtual servers are located on a private LAN within Rackspaces' London data centre and provide essential services such as web and email. The office machines are on a local network in the London office, administered by XXXXXX.
Requirements
An overall solution is required to securely backup essential Wikimedia UK data for the purposes of security and disaster recovery. The key requirements are:
- Secure backups: data must be securely encrypted
- Offline backups: ability to place recent copies of backups in a fire safe
- Easy to administer: office staff should be able to conduct offline backup procedure, and the system should otherwise require little to no maintenance
- Open Source: in line with Wikimedia UK's commitment to using Open Source software when appropriate
- Comprehensive: capable of backing up server information as well as local files
- Disaster Recovery: the system should form part of an automated disaster recovery plan
- Cross Platform: the system should be capable of backing up Windows/Linux/Mac
Proposed system
