Data corruption is the accidental change of a file or the loss of info that often occurs during reading or writing. The reason may be hardware or software malfunction, and as a result, a file may become partially or entirely corrupted, so it'll no longer function properly since its bits will be scrambled or missing. An image file, for example, will no longer present a real image, but a random mix of colors, an archive will be impossible to unpack as its content will be unreadable, and so on. If this kind of a problem occurs and it is not found by the system or by an administrator, the data will become corrupted silently and when this happens on a disk drive which is part of a RAID array where the data is synced between various different drives, the corrupted file will be copied on all other drives and the harm will become long term. A large number of frequently used file systems either do not feature real-time checks or don't have high quality ones which can detect an issue before the damage is done, so silent data corruption is a common issue on hosting servers where large amounts of info are stored.
No Data Corruption & Data Integrity in Shared Web Hosting
If you host your websites in a shared web hosting account from our company, you won't need to worry about any of your data ever getting corrupted. We can guarantee that as our cloud hosting platform uses the amazing ZFS file system. The latter is the only file system that works with checksums, or unique digital fingerprints, for each and every file. Any kind of info that you upload will be stored in a RAID i.e. simultaneously on many SSDs. All of the file systems synchronize the files between the separate drives using such a setup, but there's no real guarantee that a file will not get corrupted. This could happen at the time of the writing process on any drive and after that a corrupted copy can be copied on all other drives. What is different on our platform is the fact that ZFS compares the checksums of all files on all the drives live and in the event that a corrupted file is discovered, it's replaced with a good copy with the correct checksum from another drive. That way, your data will continue to be undamaged no matter what, even if a whole drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
We have avoided any chance of files getting damaged silently because the servers where your semi-dedicated hosting account will be created employ a powerful file system known as ZFS. Its main advantage over various other 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 numerous SSD drives, ZFS checks whether the fingerprint of a file on one drive matches the one on the rest of the drives and the one it has saved. When there's a mismatch, the corrupted copy is replaced with a good one from one of the other drives and considering that this happens right away, there's no chance that a damaged copy could remain on our web servers or that it can be duplicated to the other hard disks in the RAID. None of the other file systems employ such checks and what is more, even during a file system check right after a sudden power loss, none of them can detect silently corrupted files. In contrast, ZFS doesn't crash after an electrical power failure and the regular checksum monitoring makes a time-consuming file system check unnecessary.
