The process of files being corrupted because of some hardware or software failure is known as data corruption and this is one of the main problems that Internet hosting companies face because the larger a hard drive is and the more information is filed on it, the more likely it is for data to become corrupted. There are several fail-safes, still often the info becomes damaged silently, so neither the particular file system, nor the admins notice a thing. Consequently, a bad file will be treated as a good one and if the hard disk is part of a RAID, that file will be copied on all other disk drives. In principle, this is done for redundancy, but in practice the damage will get even worse. Once some file gets corrupted, it will be partly or completely unreadable, so a text file will no longer be readable, an image file will present a random mix of colors in case it opens at all and an archive will be impossible to unpack, and you risk losing your site content. Although the most frequently used server file systems include various checks, they are likely to fail to detect some problem early enough or require a vast time period in order to check all of the files and the web server will not be operational for the time being.

No Data Corruption & Data Integrity in Shared Web Hosting

We warrant the integrity of the information uploaded in any shared web hosting account which is created on our cloud platform due to the fact that we use the advanced ZFS file system. The aforementioned is the only one that was designed to prevent silent data corruption using a unique checksum for each file. We will store your info on multiple NVMe drives that work in a RAID, so the same files will be accessible on several places at once. ZFS checks the digital fingerprint of all files on all of the drives in real time and in case the checksum of any file differs from what it should be, the file system swaps that file with an undamaged copy from a different drive in the RAID. No other file system uses checksums, so it's easy for data to be silently corrupted and the bad file to be replicated on all drives with time, but since this can never happen on a server running ZFS, you don't have to concern yourself with the integrity of your information.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We've avoided any probability of files getting damaged silently because the servers where your semi-dedicated hosting account will be created take advantage of a powerful file system called ZFS. Its advantage over alternative file systems is that it uses a unique checksum for each file - a digital fingerprint which is checked in real time. Since we save all content on numerous NVMe drives, ZFS checks whether the fingerprint of a file on one drive matches the one on the other drives and the one it has stored. In the event that there's a mismatch, the bad copy is replaced with a good one from one of the other drives and since it happens right away, there's no chance that a damaged copy could remain on our servers or that it can be copied to the other hard disks in the RAID. None of the other file systems use this type of checks and what is more, even during a file system check after an unexpected power failure, none of them will detect silently corrupted files. In comparison, ZFS won't crash after a power failure and the constant checksum monitoring makes a lenghty file system check obsolete.
