Is there a file system that does error correction?
I am looking for some virtual file system (e.g. with virtual hard disk) or some other kind of working solution to create archives or data backups with error correction redundancy.
I tried looking for something like Windows 7 VHD, which can be displayed as a new storage device with its own FS, but having a certain configurable percentile of recovery warranty on the files.
In other words, I'd like to have a VHD or something similar, which I can configure setting a certain recovery percentile (e.g. 10%) and the target is the files on this drive could be corrupted up to 10% and they will be recoverable.
To be more precise, the idea is similar to an "encrypted" FS (eg. TrueCrypt), but with redundancy for reliability instead of encryption for privacy and security.

It sounds like what you want is software RAID. There's no point in error correction on one drive because the drive as a whole is the most likely point of failure and drives already have error detection in hardware.

Software RAID needs more than one hard drive. This would be a good solution if i could reserve a PC with multiple hard drives and a software raid layer over them. Really, this is a "bad copy" of a RAID hardware solution, so it's not what i was looking for. I need to plug an USB external storage to some notebooks and back up data. I know a single hard drive is not a "real" solution because with a mechanical failure of the drive all data will be lost.

If you only have one drive, it's hopeless. The most likely failure is the loss of that drive, and then what can you do? Also, something odd is going on with your question. If this is for backup, why does it need to be so reliable? Won't you still have the original if the backup system fails? If you really mean this is instead of backup, you're really going the wrong way!

I simply want a "more reliable" solution then a standard one, because often happens that some few clusters damages over time. If data are not lost after the damaged clusters detection, i can replace the new drive having not lost any data.

Considering to use 2+ drives and replicate backups is in the same direction of disk redundancy, so it is an hw solution. Then i think it will be better to buy a NAS with raid support.

I haven't heard of one that works like a block-level filesystem.
Tahoe-LAFS does have this feature but it works more like FTP, it's slow, and really is designed to spread shares amongst multiple hosts.
You could always make your files redundant yourself using a PAR2 tool such as QuickPar.

It sounds like what you want is software RAID. There's no point in error correction on one drive because the drive as a whole is the most likely point of failure and drives already have error detection in hardware.

Software RAID needs more than one hard drive. This would be a good solution if i could reserve a PC with multiple hard drives and a software raid layer over them. Really, this is a "bad copy" of a RAID hardware solution, so it's not what i was looking for. I need to plug an USB external storage to some notebooks and back up data. I know a single hard drive is not a "real" solution because with a mechanical failure of the drive all data will be lost.

If you only have one drive, it's hopeless. The most likely failure is the loss of that drive, and then what can you do? Also, something odd is going on with your question. If this is for backup, why does it need to be so reliable? Won't you still have the original if the backup system fails? If you really mean this is instead of backup, you're really going the wrong way!

I simply want a "more reliable" solution then a standard one, because often happens that some few clusters damages over time. If data are not lost after the damaged clusters detection, i can replace the new drive having not lost any data.

Considering to use 2+ drives and replicate backups is in the same direction of disk redundancy, so it is an hw solution. Then i think it will be better to buy a NAS with raid support.
