We are setting a Disaster Recovery plan in place for our network. We currently have a few web servers, a couple Active Directory servers and some file servers.
Here is the layout of the servers:
1. Windows Server 2003, using about 30GB of data
2. Windows Server 2003, only holds about 20GB of data
3. Windows Server 2008 R2, holds up to 1TB (currently uses 500GB)
4. Widnows Server 2008 R2, holds up to 2TB (currently uses 1TB)
Active Directory Servers:
1. Windows Server 2008 R2, using about 30GB of data
2. Windows Server 2008 R2, using about 30GB of data
1. Windows Server 2003, holds up to 2TB (only 750GB in use)
2. Windows Server 2003, using 60GB data
3. Windows Server 2003, using 120GB data
A couple of the web servers have very important applications and files that we don't really have a copy of and a couple of the file servers have SQL on them as well.
What would be the best all-around solution to backup these servers (or main ones) as real-time snap shot images (OS, Files, and data) so that in case of failure or disaster we can turn on a image of them? This would all no downtime and give us time to fix the servers. We also don't have a huge budget but would be ideal to have something onsite and offsite.
All suggestions are welcomed and appreciated. Thanks
