Data corruption is the unintentional transformation of a file or the losing of info which usually occurs during reading or writing. The reason can be hardware or software fail, and as a result, a file can become partially or entirely corrupted, so it will no longer function properly as its bits will be scrambled or missing. An image file, for example, will no longer display a real image, but a random mix of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etc. In case this kind of a problem appears and it's not recognized by the system or by an administrator, the data will get corrupted silently and in case this happens on a disk drive that is a part of a RAID array where the info is synced between different drives, the corrupted file will be copied on all other drives and the damage will be permanent. A large number of widely used file systems either don't feature real-time checks or do not have high quality ones that will detect a problem before the damage is done, so silent data corruption is a very common issue on web hosting servers where substantial amounts of info are kept.
No Data Corruption & Data Integrity in Shared Hosting
We warrant the integrity of the information uploaded in any shared hosting
account which is generated on our cloud platform since we employ the advanced ZFS file system. The latter is the only one that was designed to avert silent data corruption through a unique checksum for each and every file. We shall store your info on a number of SSD drives which function in a RAID, so exactly the same files will exist on several places simultaneously. ZFS checks the digital fingerprint of all of the files on all of the drives in real time and in the event that the checksum of any file is different from what it has to be, the file system swaps that file with a healthy version from some other drive within the RAID. No other file system uses checksums, so it is possible for data to become silently corrupted and the bad file to be duplicated on all drives over time, but since this can never happen on a server running ZFS, you won't have to worry about the integrity of your info.
No Data Corruption & Data Integrity in Semi-dedicated Servers
We've avoided any possibility of files getting corrupted silently as the servers where your semi-dedicated server
account will be created employ a powerful file system named ZFS. Its main advantage over alternative file systems is that it uses a unique checksum for each and every file - a digital fingerprint that is checked in real time. Since we keep all content on a number of SSD drives, ZFS checks whether the fingerprint of a file on one drive corresponds to the one on the other drives and the one it has saved. In case there is a mismatch, the corrupted copy is replaced with a good one from one of the other drives and since this happens right away, there's no chance that a corrupted copy could remain on our website hosting servers or that it can be copied to the other hard disks in the RAID. None of the other file systems include such checks and in addition, even during a file system check right after an unexpected electrical power failure, none of them can discover silently corrupted files. In contrast, ZFS won't crash after a power failure and the constant checksum monitoring makes a lenghty file system check obsolete.
