Data corruption is the unintentional change of a file or the loss of info that often occurs during reading or writing. The reason could be hardware or software fail, and as a consequence, a file may become partially or entirely corrupted, so it will no longer function as it should because 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 because its content will be unreadable, and so on. When such a problem appears and it's not recognized 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 info is synced between various different drives, the corrupted file shall be reproduced on all other drives and the harm will be permanent. A number of frequently used file systems either don't have 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 problem on web hosting servers where huge volumes of data are stored.

No Data Corruption & Data Integrity in Website Hosting

In case you host your Internet sites in a website hosting account from our company, you won't need to worry about your data ever getting damaged. We can guarantee that because our cloud hosting platform employs the outstanding ZFS file system. The aforementioned is the only file system that works with checksums, or unique digital fingerprints, for every single file. Any kind of info that you upload will be kept in a RAID i.e. simultaneously on numerous NVMes. All the file systems synchronize the files between the separate drives using such a setup, but there's no real warranty that a file will not be corrupted. This may occur at the time of the writing process on each drive and afterwards a damaged copy can be copied on the rest of the drives. What makes the difference on our platform is that ZFS examines the checksums of all files on all of 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 information will continue to be undamaged no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

In case you purchase one of our semi-dedicated hosting packages, you will not have to worry about silent data corruption as we use ZFS - an advanced file system which checks all files in real time. Every time you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synchronized between multiple NVMe drives for redundancy, so if a drive fails, the other ones will take control. ZFS compares the checksum of all copies on the different drives and if it detects a corrupted copy, it replaces it with a healthy one from a different drive. This is done immediately, so there will be no risk for any part of your content at any time. In comparison, alternative file systems execute checks only after a system breakdown, but since they don't use anything similar to the checksums that ZFS uses, they won't detect silently corrupted files, so a corrupted copy could be replicated on the remaining drives as well and you can lose critical data. Since this is not the case with ZFS, we're able to guarantee the integrity of each and every file you upload no matter what.
