The process of files being corrupted caused by some hardware or software failure is referred to as data corruption and this is one of the main problems which 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 become corrupted. You'll find a couple of fail-safes, but often the info is damaged silently, so neither the file system, nor the administrators see a thing. Because of this, a corrupted file will be handled as a standard one and if the hard disk is a part of a RAID, the file will be duplicated on all other disk drives. In principle, this is done for redundancy, but in reality the damage will get worse. Once some file gets damaged, it will be partially or fully unreadable, so a text file will no longer be readable, an image file will show a random combination of colors if it opens at all and an archive will be impossible to unpack, so you risk losing your website content. Although the most widespread server file systems have various checks, they frequently fail to discover a problem early enough or require a long period of time in order to check all files and the server will not be functional in the meantime.

No Data Corruption & Data Integrity in Shared Hosting

We have dealt with the issue of silent data corruption on our shared hosting servers by using the cutting-edge Z file system, or ZFS. The latter is better than other file systems because it is the only one on the market which checks all the files right away by using a checksum - a digital identifier that is unique for every single file. When you upload content to your account, it'll be stored on several NVMe drives and constantly synced between them for redundancy. ZFS constantly examines the checksum of all files and if any file is detected as corrupted, it's replaced promptly with a good copy from some other disk. As this happens in real time, there is no risk that a bad file may remain or may be duplicated on the rest of the NVMes. ZFS needs lots of physical memory to execute the real-time checks and the advantage of our cloud hosting platform is that we employ multiple powerful servers working together. In case you host your Internet 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 resistant to silent data corruption because all our storage servers make use of the innovative ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, to verify the integrity of every single 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 drives. All the copies of a specific file will feature the same checksum on all drives and ZFS will compare the checksums of the copies in real time, so if it finds a mismatch, that will indicate that one of the copies is damaged, it'll replace that file with a healthy copy from one of the other drives. Even if there's an unforeseen power failure, the data on the servers will not be corrupted and there will not be any need for a time-consuming system check that other file systems perform after some malfunction, extending the time needed for the server to get back online. ZFS is the file system that can really protect your content from silent data corruption.
