I read a bit but not sure if i need RAID 1,2,3,4,5,10? I assume it is like a backup? I have a social network running on mysql and php and have no backups currently. It is dedicated hosting with some CDN. So firstly do i need any RAID? If so what type and are there any extra hardware/software/costs with each RAID number? And software / hardware or both?

    Having no backups is the same as saying *"My data have no value"*. – jscott Dec 17 '10 at 16:25

    @jscott - +1 for the comment, and using 'data' as a plural (which it is!) – Andrew Barber Dec 17 '10 at 16:28
  • I am not sure how to setup backups so was looking into this now. Its complex with social networks which are updated 24-7-365 and i cannot take it offline also. – mikey Dec 17 '10 at 16:30

    Your assumption that raid is like a backup is wrong, wrong, wrong. – GregD Dec 17 '10 at 16:37

    @Mikey - given what you're asking, I would suggest that you hire a professional. There's no modern database that I can think of that won't allow you to take online backups. – mfinni Dec 17 '10 at 16:38
  • Ok, professional hire it is! I assume a system admin should be able to handle all these or some other IT profession is needed? – mikey Dec 17 '10 at 16:50
  • Yes - systems admin or systems engineer, or "server" instead of "systems", or some might just call themselves "consultant". Good luck. – mfinni Dec 17 '10 at 17:09
  • Actually - when you're looking for someone, list all of the technologies (server OS, mysql, apache) that are in your product, and find someone who knows them. Job titles in IT aren't remarkably standardized. – mfinni Dec 17 '10 at 17:10

Ask your hoster what is configured for you. If you're paying someone else to manage the hardware, get your money's worth.

Also, pay for backups. RAID is not backup.

/Edit - if you were a sysadmin, I'd have a lot more suggestions, but that's not how your phrased the question so I don't think getting into the weeds is relevant or helpful.

  • +1 for the important information without extra info which seems wouldn't be helpful here (re the OP apparently not being a sysadmin) – Andrew Barber Dec 17 '10 at 16:29

If you have a "social network" running on mysql and php AND you have no backups and don't know what version of RAID you might need, then I'm afraid that you've put the cart WAAAAAAAAY before the horse.

My advice is to take a step back and hire a good sysadmin before you take your site live because your site isn't live with actual users right?.

  • Not yet, it's in beta hence I am trying to look into these issues before i make it offical. – mikey Dec 17 '10 at 16:49
  • I'm gonna be cynical now, and say we've got enough social networks. I bet you won't get more than a few hundred users. Is it worth it? Probably not. Can you just use a facebook group? Probably. – Tom O'Connor Dec 17 '10 at 17:30
