Forgive me if this is a newbie question.
We have Plesk 10.2.0 on CentOS5. We also have a second, older server also with CentOS5. I want to set up 2 things:
1. Linux High Availability between the 2 servers so if one went down everything would automatically flip to the second server which would be up to date with emails, websites etc. and avoid down-time. Lots of questions come from it:
- surely for a failover server we di not need to purchase a second Plesk licence? They are not cheap, and we pay hundreds of dollars each year to renew our licence (unlimited domains). Surely others doing this are not purchasing additional licences just for the failover peace of mind?
2. We have an external mx backup which has little/no spam protection. I would like our mx backup to be on our second server if that is possible as well, without prejudicing serial 1 above.
3. I would like us to be doing our own secondary name servers on the second server - most likely linked to serial 1 above.
Please could the experts guide me and advise on best practice to achieve the above.
