Raids and Backups?

[cakez]

To Backup my files,should I back them up on a raid 1 ,or just back it up on a hard drive?

Both, have them on your main pc and then if possible have a nas in raid 1.

An extra backup in the cloud is also handy in case of a fire.

Depends on how many hard drives you're going to put into it. 

4 or more - Raid 10

2-4 - Raid 1

 

If you really care about reliability you should get HGST NAS hard drives ( those have a very low failure rate ) and look into Freenas, it has support for ZFS.

First off, RAID is redundancy, IT IS NOT backup.

Raid will only protect from hardware failure, it will not protect from software failure, data corruption, deletion, natural disaster, or various other issues.

For a true 'backup' you should be storing an additional copy on another physical device, ideally in another geographic location if at all possible. Depending on the amount of data you want to backup, simply getting an external drive that you backup to every so often and store at a family member/friends house may be an option, I know of one person who actually rents a safety deposit box at his bank and stores a backup drive there. If you have a good internet connection options like BackBlaze or CrashPlan are great and extremely affordable.

Now if you want to set up a RAID for redundancy it really depends on how many drives you are going to have. If it's just 2, RAID 1 is your only option. If your using 4 or more you can go to RAID 10. If you have a decent RAID controller you can even look into things like RAID 5 or 6. If you plan on building a dedicated NAS you could also look into running FreeNAS which supports various software RAID modes.

For a RAID 0, 1, or 10 you really don't need a dedicated RAID controller. Nearly every motherboard ships with RAID 0, 1, and 10 capabilities baked in. Just use that. Those RAID level require practically no overhead so it isn't an issue. You only really need a dedicated RAID controller if you are going to be using RAID 5, 6, or some of the other more exoctic RAID levels.
