Data corruption is the unintended transformation of a file or the losing of information that often occurs during reading or writing. The reason can be hardware or software malfunction, and consequently, a file may become partially or completely corrupted, so it will no longer work as it should because its bits shall be scrambled or lacking. An image file, for example, will no longer show a true image, but a random combination of colors, an archive will be impossible to unpack because its content will be unreadable, etc. When such an issue appears and it is not found by the system or by an administrator, the data will get corrupted silently and when this happens on a disk drive that is part of a RAID array where the information is synced between various drives, the corrupted file will be replicated on all other drives and the harm will become permanent. A number of popular file systems either do not have real-time checks or do not have high quality ones which can detect an issue before the damage is done, so silent data corruption is a rather common issue on internet hosting servers where huge amounts of data are kept.

No Data Corruption & Data Integrity in Shared Website Hosting

The integrity of the data which you upload to your new shared website hosting account shall be guaranteed by the ZFS file system that we work with on our cloud platform. The majority of hosting suppliers, like our company, use multiple hard disks to keep content and considering that the drives work in a RAID, the exact same information is synchronized between the drives all the time. When a file on a drive becomes damaged for reasons unknown, yet, it is likely that it will be duplicated on the other drives as other file systems do not feature special checks for this. Unlike them, ZFS uses a digital fingerprint, or a checksum, for every file. In the event that a file gets corrupted, its checksum won't match what ZFS has as a record for it, and the bad copy will be swapped with a good one from another hard disk. Because this happens immediately, there's no risk for any of your files to ever get corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

If you buy one of our semi-dedicated hosting packages, you won't have to be concerned about silent data corruption since we use ZFS - a high level file system that monitors all files in real time. Whenever you upload a file to your website hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synced between a number of NVMe drives for redundancy, so if a drive fails, the other ones will take over. ZFS compares the checksum of all of the copies on the different drives and when it detects a corrupted copy, it replaces it with a healthy one from a different drive. This is done right away, so there will be no threat for any part of your content at any moment. By comparison, other file systems carry out checks only after a system malfunction, but since they do not use anything similar to the checksums which ZFS uses, they can't detect silently corrupted files, so a bad copy could be replicated on the rest of the disks as well and you may lose crucial data. Because this is not the case with ZFS, we're able to guarantee the integrity of every single file you upload no matter what.
