The process of files being corrupted because of some hardware or software failure is called data corruption and this is among the main problems that web hosting companies face as the larger a hard disk drive is and the more info is filed on it, the more likely it is for data to be corrupted. You'll find several fail-safes, yet often the information gets corrupted silently, so neither the file system, nor the administrators detect anything. Thus, a corrupted file will be treated as a good one and if the hard disk is a part of a RAID, the file will be duplicated on all other drives. In principle, this is for redundancy, but in practice the damage will get even worse. The moment a file gets corrupted, it will be partially or fully unreadable, so a text file will no longer be readable, an image file will present a random combination of colors in case it opens at all and an archive shall be impossible to unpack, so you risk sacrificing your content. Although the most commonly used server file systems feature various checks, they frequently fail to detect some problem early enough or require a vast amount of time in order to check all the files and the web server will not be operational for the time being.

No Data Corruption & Data Integrity in Website Hosting

We've dealt with the issue of silent data corruption on all of our website hosting servers by using the state-of-the-art Z file system, or ZFS. The latter is more advanced than other file systems as it is the only one out there which checks all files immediately by employing a checksum - a digital identifier that's unique for every single file. When you upload content to your account, it'll be stored on several NVMe drives and continually synchronized between them for redundancy. ZFS regularly analyzes the checksum of all files and in the event that any file is detected as damaged, it is replaced quickly with a good copy from some other disk. As this happens in real time, there's no risk that a bad file may remain or may be duplicated on the rest of the NVMes. ZFS needs a lot of physical memory to carry out the real-time checks and the advantage of our cloud web hosting platform is that we work with multiple very powerful servers working together. In case you host your websites with us, your information 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 our storage servers work with the efficient ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, in order to guarantee the integrity of each and every file. When you upload content to your account, it will be saved on several redundant drives in a RAID i.e. the files shall be the same on all disks. All the copies of a specific file will have the same checksum on all drives and ZFS will compare the checksums of the duplicates in real time, and if it finds a mismatch, which will indicate that one of the copies is corrupted, it will 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 will not get corrupted and there won't be any need for a time-consuming system check which other file systems perform after some breakdown, lengthening the time needed for the server to return online. ZFS is the sole file system that can really protect your content from silent data corruption.
