I have a linux server whic is used as web/file/svn/sql server. It is accessed by 100 machines for storing their code files on this server(svn/code/mysql).
The OS is on a 80 GB HDD. The data is on another 500 GB HDD. Which is the best way to make a HA server?
1: Can I use rsync to mirror to a replicated server of the same config or should I add in another HDD and set up rsync to replicate the data. It's a basic server, so I dnot have hardware RAID 1(for mirroring).
2: Also if I set u rsync to run every 1 hour, will it increase server load to find the files which were changed in the past 1 hour and then copy to the backup server?
