Data corruption is the unintentional change of a file or the loss of info that usually occurs during reading or writing. The reason can be hardware or software failure, and because of this, a file can become partially or fully corrupted, so it'll no longer work as it should since its bits shall be scrambled or lost. An image file, for instance, will no longer display an authentic image, but a random mix of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etcetera. If this kind of a problem appears and it isn't identified by the system or by an admin, the data will be corrupted silently and when this happens on a disk drive which is a part of a RAID array where the info is synced between different drives, the corrupted file shall be copied on all of the other drives and the damage will become long term. Numerous frequently used file systems either do not feature real-time checks or do not have good ones that will detect a problem before the damage is done, so silent data corruption is a very common matter on hosting servers where huge amounts of info are kept.

No Data Corruption & Data Integrity in Shared Web Hosting

We guarantee the integrity of the information uploaded in any shared web hosting account which is generated on our cloud platform as we use the advanced ZFS file system. The latter is the only one that was designed to avoid silent data corruption through a unique checksum for every single file. We will store your info on multiple NVMe drives that work in a RAID, so the exact same files will exist on several places simultaneously. ZFS checks the digital fingerprint of all files on all drives in real time and if the checksum of any file is different from what it should be, the file system swaps that file with a healthy copy from a different drive in the RAID. There's no other file system that uses checksums, so it's easy for data to be silently damaged and the bad file to be duplicated on all drives over time, but since that can never happen on a server running ZFS, you don't have to concern yourself with the integrity of your data.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be shielded from silent data corruption because all our storage servers employ the state-of-the-art ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, to ensure the integrity of each and every file. When you upload content to your account, it'll be placed on a couple of redundant drives employed in a RAID i.e. the files shall be the same on all drives. All copies of a specific file will have the same checksum on all hard disks and ZFS will compare the checksums of the duplicates quickly, so if it detects a mismatch, that will indicate that one of the copies is damaged, it will replace that file with a good copy from one of the other disks. Even if there's an unforeseen blackout, the data on the servers won't get corrupted and there will not be any need for a time-consuming system check that other file systems perform following some breakdown, extending the time needed for the server to go back online. ZFS is the sole file system that can really protect your content from silent data corruption.
