The process of files getting corrupted because of some hardware or software failure is referred to as data corruption and this is one of the main problems which hosting companies face as the larger a hard disk is and the more information is filed on it, the much more likely it is for data to become corrupted. You can find a couple of fail-safes, but often the information is damaged silently, so neither the file system, nor the admins detect anything. As a result, a damaged file will be handled as a regular one and if the HDD is part of a RAID, that file will be copied on all other disk drives. In theory, this is for redundancy, but in reality the damage will get worse. The moment a file gets damaged, it will be partly or completely unreadable, which means that a text file will not be readable, an image file will show a random blend of colors if it opens at all and an archive shall be impossible to unpack, and you risk losing your site content. Although the most widespread server file systems feature various checks, they are likely to fail to detect a problem early enough or require an extensive amount of time to check all of the files and the hosting server will not be operational for the time being.

No Data Corruption & Data Integrity in Shared Hosting

We have resolved the problem of silent data corruption on all our shared 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 out there which checks all files in real time by employing a checksum - a digital identifier that's unique for each and every file. When you upload content to your account, it'll be stored on several NVMe drives and regularly synced between them for redundancy. ZFS regularly compares the checksum of all files and in the event that any file is detected as corrupted, it is replaced promptly with a good copy from another 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 lots of physical memory in order to execute the real-time checks and the benefit of our cloud web hosting platform is that we work with multiple powerful servers working together. In case you host your Internet sites with us, your info will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be resistant to silent data corruption since all of our storage servers use the effective ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, in order to verify the integrity of each file. When you upload content to your account, it'll be placed on several redundant drives employed in a RAID i.e. the files shall be the same on all drives. All copies of a specific file will feature the same checksum on all drives and ZFS will compare the checksums of the copies right away, so if it identifies a mismatch, that would indicate that one of the copies is corrupted, it'll replace that file with a healthy copy from one of the other disks. Even if there is an unexpected power loss, the data on the servers won't be corrupted and there will not be any need for a time-consuming system check that other file systems perform following some failure, extending 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.
