OVH.com has "softraid" for all their servers. Does it mean my data is protected if my server fails?

It's software RAID, so typically RAID either at BIOS or OS level rather then a physical RAID controller card.Mechanical Bunny Media

It´s a software raid and it´s only protected if 1 hard drive fails.Comment

Don't onboard controllers usually depend on the cpu some up to a lot? I'm asking because I don't know but why soft raid would be a good idea for servers would be beyond meComment

RAID is being controlled by software.Comment

Wow, I wouldn't want to be on the same box with some other idiot using software raid if it works the way I think it does. That's for sureComment

you can select the non software raid.
depends if you are on vps or dedicated.
im on the SP-64 Server line with the hard raid option, but if its vps i dont think you have a choice.Since 1999: 69 Adult Industry awards for Best Hosting Company and professional excellence.

There's a reason why Hardware Raid is more expensive than Software Raid (usually free)... the hardware option is a much better one. It amazes me, however, that so many people I know spend the extra money on a hardware raid but then don't get the BBU option.NSFWComment

This is exactly where a BBU would have helped as it stores data in a cache that can be written back to the raid when the replacement drive is added. It won't power the RAID, but will provide a pretty decent window to have the drive replaced without the loss of data.
Of course, this necessitates having a hardware raid too.NSFWComment

RAID1 or RAID5/RAID6 will protect you from data loss if a drive fails, but there are still a number of scenarios where data can become (often silently) corrupted.
RAID is a fairly simple, old school technology. These days there are file systems which offer RAID-like redundancy, but provide higher level protection. ZFS checksums the data on every read, and if the checksum fails (data corrupt) it can self heal by (a) reading the same data from elsewhere (eg another drive) and (b) rewriting the corrupt data with the correct data. The best you'll get with RAID is an error when it detects that two versions of the same data are different...but which one (if any) is correct?Comment

That may be the case. I have no idea to be honest. I'm certainly stuck in my ways though in that I would always take a hardware raid with a BBU on a RAID10, 50 or 60. I'm not really much of a fan of RAID5, but I do like RAID10, in particular, for databases and always prefer a quality hardware raid controller, like an LSI product. As such, I've always balked at even the hint of a software raid when ordering servers, so my experience with software raid is extremely limited.NSFWComment
