I have had better luck with software raid myself, specifically ZFS RaidZ1 and Mirrored Storage Spaces with ReFS on Server 2012 / Windows 8. I rate both of them highly because they close the RAID write hole by using copy on write. Linux md raid has been a mixed bag for me not because any type of wierd thrashing, but because its given me trouble rebuilding the array before in RAID10 mode. I was ultimately able to fix the server after about half a day of downtime... yeah, not fun. Had similar experiences with you using cheapo Hardware / Fake RAID.

Ask ralphie about my backup.

3 x 16 TB or audio computers
Have a schedule I do backups.
3 redundancies and then the actual drives in the computer.

One set is in a fire resistant safe


And soon to have everything on cloud.

Make sure the cloud solution you go with keeps your data in at least two/three different physical locations. Amazon S3 works this way by default. The chances of them not losing your data is like 99.999999999%. A meteor is more likely to hit and destroy the earth than them losing your data, provided they stay in business

Not sure what the more consumer oriented cloud storage (Dropbox etc) policy is on that.

If you also need protection from electronic theft, you should encrypt your backups before sending them to the cloud that way a rogue employee can't do any damage, though many providers such as Amazon are very strict about limiting employee access to data.

Raid 1 is just a cheapo way to have a mirrored backup. I'm not saying it's the best way to back up files, let alone in a business\IT environment. But for home use or single workstation it provides some redundancy for failed storage drives.

RAID 1 is an uptime solution, not a backup solution. Big difference. Don't use the word backup, or you'll have peeps on your case.

A simple backup tool like Time Machine is superior to RAID 1 for home or office use.

if i die, everything is available for my family to listen to while grieving, then ive also made a letter than explains that everythings to be released somehow. supersafe.


Lol, I would have thought you needed one of these (I sure as shit know Richie does):



All this talk of RAID though as backup, unless things have changed(?), is a terrible idea as Echosystem pointed out;

You actually double the chances of something going wrong - two drives = double the chances of failure. Sure, it won't mean down time, but it 's not a good backup solution.

And correct me if I'm wrong, but I thought software RAID wan't worth the disk space it used up?

I don't have much custom sample data or recorded audio tracks. Most projects are MIDI based with only a few actual audio tracks so backing up is as easy as alternatively saving to two separate hard drives.
I don't bother to backup my system drive so it does mean if it fails I will lose about a week installing everything again.

Is there anything like Time Machine for Windows where I can configure what needs to be backed up and what doesn't?

I should be ok though as long as Godzilla doesn't crush my 'puter.

First of all, the chances of failure are only double if you use RAID 0. RAID 0 stripes the data between two drives for additional performance and larger individual volume size over using two separate drives.

There is no difference in space used between hardware and software raid. There is difference in spaces used between the different RAID levels. The only RAID level that doesn't sacrifice any drive space is RAID 0 (which doubles your rate of total data loss).

RAID 1 isn't a backup but generally it does mean you can have one drive die of a mechanical/electrical failure and you won't have to restore everything from a backup. You just put another drive in and rebuild the array.

The reason RAID (besides RAID 0) is not a backup is fairly simple, it only protects you against drive failure. It does jack shit against accidental deletion, ransomware like cryptolocker, bugs wiping out your filesystem, etc. Not to mention it offers no additional protection against theft or natural disasters (only remote backup can offer that).

EDIT:

Also one more thing to note is that RAID 2,3,4 and 5 should be considered obsolete. This includes X0 variations as well. The reason for RAID 5 being obsolete is a recent development. The rebuilding process is very likely to fail with RAID 5 because while the amount of storage has increased, the rate of URE (Uncorrectable Read Error) has stayed constant. Basically you are likely to have a URE while rebuilding your array which can make the process fail.

Windows 8 has File History which is basically the same thing as Time Machine. I use it as one of my online backup solutions and it works great.
