Mark Lomas discusses disaster recovery for IT infrastructure. Traditional backup software is not sufficient and only captures certain file data, not full system images. A better approach uses replication of file servers, email, databases and other critical systems to a remote site, along with virtualization and centralized storage. This allows for rapid recovery of the full system after a disaster rather than just individual files. Remote access is also important to provide users a way to access the recovered systems. Proper preparation through approaches like replication, virtualization and remote access is key to effective disaster recovery.

- 16. Summary • Tape alone is not good enough • Complete ‘imaging’ allows for rapid recovery • An environment to recover to, and spare hardware (or hosting!) • Virtualisation & SAN can help make things even easier! • Remote access to give users a ‘way in’ • Be proactive – preparation is everything!

Hinweis der Redaktion
- Thank you <previous>Thank all for comingTake a look at the IT side of DR
- A little about me8 years at IcommHeavy technical background
- ServersNetworkingPCs & DevicesWhy Infrastructure? Because backup and DR operate at this level
- Allot of people thinking ‘I’ve got tape’Is this good enough?
- Lets look at what would be needed to get back to normal
- Would work – but would take huge amounts of timeTime is something you don’t have.
- So, is tape backup good enough?NO!
- A better way – complete server protection‘Imaging’ – entire servers converted to files
- Each server image can be used to recreate a server‘Personality’ of server is restored.Combined with tape, server is up to date.
- How do people get to the servers once they’re back?Remote access
- If you don’t have a second site – a hosting providerHost it in the cloud
- If you virtualise, or thinking of this, it can make things even easierA Virtual machine is already an imageUsually based on a ‘SAN’The better SANs include replication.
- For failure – the second SAN already has the data, no restore needed
- To expand on how users gain access….Remote desktop serverWith a remote access appliance, getting users through is easy.
- Thanks!
