Data corruption is the unintentional change of a file or the loss of info which usually occurs during reading or writing. The reason could be hardware or software failure, and as a consequence, a file can become partially or fully corrupted, so it will no longer function properly because its bits will be scrambled or lacking. An image file, for example, will no longer display an authentic image, but a random combination of colors, an archive will be impossible to unpack because its content will be unreadable, etcetera. If this kind of a problem occurs and it's not identified by the system or by an administrator, the data will get corrupted silently and if this happens on a disk drive which is a part of a RAID array where the data is synchronized between various drives, the corrupted file will be copied on all of the other drives and the damage will become permanent. Many popular file systems either don't feature real-time checks or do not have good ones that can detect a problem before the damage is done, so silent data corruption is a common matter on hosting servers where huge amounts of information are kept.

No Data Corruption & Data Integrity in Cloud Web Hosting

The integrity of the data that you upload to your new cloud web hosting account shall be ensured by the ZFS file system which we use on our cloud platform. The vast majority of web hosting service providers, including our company, use multiple hard drives to keep content and considering that the drives work in a RAID, the exact same info is synchronized between the drives all the time. In case a file on a drive becomes damaged for some reason, yet, it is more than likely that it will be duplicated on the other drives since alternative file systems do not feature special checks for this. Unlike them, ZFS applies a digital fingerprint, or a checksum, for each and 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 shall be swapped with a good one from another disk drive. Since this happens immediately, there is no possibility for any of your files to ever get damaged.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

If you purchase one of our semi-dedicated hosting solutions, you won't have to be concerned about silent data corruption since we use ZFS - an advanced file system which keeps track of all the files in real time. Each time you upload a file to your web hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synchronized between multiple SSD drives for redundancy, so if one drive fails, the other ones will take control. ZFS compares the checksum of all copies on the different drives and when it detects a corrupted copy, it replaces it with a healthy one from another drive. This happens immediately, so there will be no risk for any part of your content at any moment. In comparison, all of the other file systems perform checks only after a system malfunction, but since they don't use anything similar to the checksums which ZFS uses, they will not detect silently corrupted files, so a bad copy could be replicated on the rest of the disks as well and you may lose important info. As this isn't the case with ZFS, we're able to guarantee the integrity of each and every file you upload no matter what.
