I am researching open source and free disaster recovery options for implementing VMWare Server (Free version). I want the Virtual machine files to replicate to another server, which I activate if the first one fails. So far I'm looking at two options:
1) LVM Snapshots, with periodic sync through rsync or the like
2) DRDB live replication
I'm looking at the downside of trying this. People who have experienced problems in live environments with either of these setups. Please advise on what I should beware of with LVM/DRDB, and if alternative methods exist that will be better. As far a possible, Free and/or Open Source solutions.
Thank you very much for any input!
