First, let me apologize for bad English.
I've seen much worse without apologies
1) I will have full access to my files on it? Can I send script, map, edit, etc?
Yes, anytime.
2) I will receive support (free) if you compile a distro for me and it returns crashes?
We compile the TFS, but if you use an unstable and not newest (trunk) version, we are not able to help you. If that is newest version, we assist in getting the bug fixed with the developers. In most cases, however, it is the problem with your scripts.
3) In addition to the monthly cost, I will have to pay other fees? If I need support with any errors that cause problems in OTServ?
There are no other fees. The support included in price covers setting up your server (transferring files, setting up database, compiling and starting TFS). Any errors in the Lua scripts etc, are not covered by the support. (If they were, we would be making OTServer for you completely...)
4) The support is made that way (ticket, chat, etc.)?
Ticket/email - quick replies and always available.
Chat - sometimes offline, but I'm available via email.
5) You said that the distro is included in the price, but future updates, if I ask, will be recompiled as well?
Whenever you want to change revision number, there are already precompiled binaries or we will do that free-of-charge.
6) I have a domain registered, it need two dns to work. Will you provide me with the two dns?
Yes. You can even get some email accounts in that domain (included in price). However you cannot add them yourself, you need to open support ticket to ask me. There is no strict email accounts limit - as many as you really need. Antispam&Antivirus protected.
7) You make automatic backups of data and BD? If yes, how often per month?
Database is backed up every day and stored in a directory accessible for you. If you need database backups twice a day, we can set it up. The rest of the files is backed up for security reasons but usually cannot be restored on request. If you need some sort of incremental backup, we can arrange that.
8) Made all these questions, I wonder how all this will cost me in a server 4 gb.
4 GB -> 40 euro per month.
Btw, thanks for help, Damon
