I admin a dedicated server that hosts a multiplayer game.
This game uses a map that now is 1.5 GB but will be soon 2.3 GB. We have just one SATA HD.
We would like to save the map every hour in the same HD to have the possibility of fresh rollbacks.
If I use rdiff-backup the players experience some "lag" (avarage is 15 seconds of 50% ticks per seconds) due to (I think) HD business. I know that some lag is necessary but what could be the best solution?
The map files are modified very often but in theory if exists a process that make slowly a backup but "consumes less HD", I think that would be the best option. Or is a stupid idea?
The map is stored in many files, like 2500, but the changing files are less than 500.
I'm very new to admin a server and I don't know so many things (english as well), so be kind.
