Iam no programer, nor am i a server hoster or sth. But as a DayZ-Player, i would like to hear why you think that way?
Because for me, server backups are the only way to ensure persistence. It's just ridiculous to think that we will be 100% safe from server crashes, and without backups, you can never provide 100% persistence to the players.
Let's say the devs reduce the issues to like 1 crash a week. Wouldn't it be possible to just "save" the server files once or two times a day, and everytime a crash occurs, just reload? (serious question lol)
I remember playin DayZ Origin in the mod version. You had these Rollbacks from time to time, but it was fine, because at least you knew that your stuff was safe.
I doubt anyone will complain if they lose some hours of progress due a crash, when their base they put days/weeks/months of work in, will be safe from whipes.
