Data corruption is the accidental transformation of a file or the losing of information which often occurs during reading or writing. The reason can be hardware or software malfunction, and for that reason, a file could become partially or entirely corrupted, so it will no longer work correctly since its bits shall be scrambled or missing. An image file, for example, will no longer display a true image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, and so on. If such an issue occurs and it isn't recognized by the system or by an admin, the data will become corrupted silently and in case 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 reproduced on all of the other drives and the damage will be permanent. Many commonly used file systems either do not have real-time checks or don't have high quality ones that can detect an issue before the damage is done, so silent data corruption is a common matter on hosting servers where large amounts of information are kept.

No Data Corruption & Data Integrity in Cloud Hosting

We've resolved the issue of silent data corruption on our cloud hosting servers by using the modern Z file system, or ZFS. The latter is better than other file systems as it is the only one in existence which checks all files in real time by using a checksum - a digital identifier which is unique for each and every file. When you upload content to your account, it'll be stored on several NVMe drives and regularly synchronized between them for redundancy. ZFS constantly analyzes the checksum of all files and in case any file is detected as damaged, it's replaced instantly with a good copy from some other disk. As this happens in real time, there is no risk that a corrupted file may remain or may be copied on the rest of the NVMes. ZFS needs a lot of physical memory in order to perform the real-time checks and the advantage of our cloud web hosting platform is that we employ multiple powerful servers working together. If you host your sites with us, your data will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be shielded from silent data corruption because all of our storage servers use the state-of-the-art ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, so as to verify the integrity of each file. When you upload content to your account, it will be saved on several redundant drives operating in a RAID i.e. the files will be the same on all disks. All copies of a given file will have the same checksum on all drives and ZFS will compare the checksums of the duplicates quickly, and if it registers a mismatch, which will indicate that one of the copies is corrupted, it'll substitute that file with a healthy copy from one of the other disks. Even if there's an unforeseen power failure, the data on the servers won't become corrupted and there won't be any need for a time-consuming system check that other file systems perform following some malfunction, prolonging the time needed for the server to go back online. ZFS is the sole file system which can really protect your content from silent data corruption.
