Data corruption is the unintentional transformation of a file or the loss of info that usually occurs during reading or writing. The reason can be hardware or software malfunction, and due to this fact, a file could become partially or entirely corrupted, so it will no longer work properly as its bits shall be scrambled or lacking. An image file, for example, will no longer display an accurate image, but a random mix of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, and so on. In the event that such an issue occurs and it's not found by the system or by an admin, the data will get corrupted silently and in case this happens on a drive that's a part of a RAID array where the information is synced between various drives, the corrupted file shall be copied on all the other drives and the damage will become long term. Many popular file systems either do not have real-time checks or do not have good ones which will detect an issue before the damage is done, so silent data corruption is a rather common matter on internet hosting servers where large amounts of data are kept.

No Data Corruption & Data Integrity in Cloud Web Hosting

In case you host your Internet sites in a cloud web hosting account with our firm, you do not need to worry about your data ever getting damaged. We can ensure that as our cloud hosting platform uses the revolutionary ZFS file system. The aforementioned is the only file system which works with checksums, or unique digital fingerprints, for each file. All of the information that you upload will be stored in a RAID i.e. simultaneously on a number of NVMe drives. All the file systems synchronize the files between the different drives with this type of a setup, but there's no real guarantee that a file will not be corrupted. This may happen at the time of the writing process on any drive and after that a corrupted copy can be copied on the other drives. What is different on our platform is the fact that ZFS compares the checksums of all files on all of the drives live and if a corrupted file is found, it's swapped with a good copy with the correct checksum from another drive. By doing this, your information will remain unharmed no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

If you go for one of our semi-dedicated server packages, you will not need to be concerned about silent data corruption since we use ZFS - an advanced file system which checks all of the files in real time. Each time you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synced between several 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 when it detects a corrupted copy, it replaces it with a healthy one from a different drive. This happens in real time, so there will be no threat for any part of your content at any time. In contrast, other file systems perform checks only after a system failure, but since they don't use anything similar to the checksums which ZFS uses, they are unable to detect silently corrupted files, so a corrupted copy could be replicated on the rest of the drives as well and you may lose critical data. Since this is not the case with ZFS, we are able to guarantee the integrity of every single file you upload no matter what.
