Data corruption is the unintentional modification of a file or the losing of info that often occurs during reading or writing. The reason can be hardware or software malfunction, and due to this fact, a file can become partially or entirely corrupted, so it will no longer work correctly as its bits will be scrambled or lacking. An image file, for instance, will no longer present a real image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, etcetera. If this kind of an issue appears and it is not identified by the system or by an administrator, the data will be corrupted silently and if this happens on a disk drive that's part of a RAID array where the data is synced between various drives, the corrupted file will be duplicated on all the other drives and the damage will be permanent. Many popular file systems either do not feature real-time checks or don't have good ones that will detect an issue before the damage is done, so silent data corruption is a rather common issue on web hosting servers where large amounts of info are kept.

No Data Corruption & Data Integrity in Cloud Website Hosting

The integrity of the data which you upload to your new cloud website hosting account will be ensured by the ZFS file system which we use on our cloud platform. The vast majority of hosting providers, like our company, use multiple hard disks to store content and since the drives work in a RAID, the exact same information is synchronized between the drives at all times. If a file on a drive gets damaged for some reason, however, it's likely that it will be reproduced on the other drives because alternative file systems don't include special checks for this. Unlike them, ZFS works with a digital fingerprint, or a checksum, for every file. In case a file gets corrupted, its checksum will not match what ZFS has as a record for it, therefore the bad copy will be replaced with a good one from another drive. Due to the fact that this happens in real time, there is no possibility for any of your files to ever be damaged.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We have avoided any possibility of files getting damaged silently because the servers where your semi-dedicated hosting account will be created use a powerful file system called ZFS. Its key advantage over other file systems is that it uses a unique checksum for each and every file - a digital fingerprint which is checked in real time. Since we save all content on numerous 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. When there's a mismatch, the bad copy is replaced with a healthy one from one of the other drives and since this happens in real time, there is no chance that a damaged copy could remain on our website hosting servers or that it could be copied to the other hard disks in the RAID. None of the other file systems work with this kind of checks and furthermore, even during a file system check right after an unexpected power failure, none of them can identify silently corrupted files. In contrast, ZFS does not crash after a power loss and the constant checksum monitoring makes a time-consuming file system check obsolete.
