The process of files being corrupted due to some hardware or software failure is called data corruption and this is one of the main problems which hosting companies face because the larger a hard disk is and the more info is placed on it, the much more likely it is for data to get corrupted. There are a couple of fail-safes, yet often the data gets damaged silently, so neither the particular file system, nor the admins notice a thing. As a result, a damaged file will be treated as a good one and if the hard disk is a part of a RAID, that file will be copied on all other disk drives. In principle, this is for redundancy, but in reality the damage will get worse. The moment a file gets corrupted, it will be partly or fully unreadable, therefore a text file will not be readable, an image file will present a random blend of colors if it opens at all and an archive will be impossible to unpack, and you risk losing your content. Although the most well-known server file systems feature various checks, they often fail to identify some problem early enough or require a long amount of time to check all the files and the web hosting server will not be operational in the meantime.

No Data Corruption & Data Integrity in Shared Hosting

We've resolved the problem of silent data corruption on all of our shared hosting servers by using the cutting-edge Z file system, or ZFS. The latter is more advanced than other file systems because it is the only one out there which checks all of the files in real time by using a checksum - a digital identifier that is unique for each file. When you upload content to your account, it will be stored on several NVMe drives and frequently synced between them for redundancy. ZFS constantly analyzes the checksum of all files and when any file is detected as damaged, it's replaced immediately with a good copy from another disk. As this happens in real time, there's no risk that a bad file may remain or may be duplicated on the remaining NVMes. ZFS needs a lot of physical memory in order to perform the real-time checks and the benefit of our cloud hosting platform is that we use multiple powerful servers working together. If you host your websites with us, your info will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be protected against silent data corruption because all of our storage servers work with the efficient ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, so as to guarantee the integrity of every single file. When you upload content to your account, it'll be kept on several redundant drives employed in a RAID i.e. the files shall be the same on all drives. All the copies of a specific file will have the same checksum on all drives and ZFS will compare the checksums of the duplicates right away, so if it identifies a mismatch, that would indicate that one of the copies is corrupted, it will replace that file with a good copy from one of the other drives. Even if there's a sudden power loss, the data on the servers won't be corrupted and there won't be any need for a time-consuming system check which other file systems perform after some failure, extending the time needed for the server to go back online. ZFS is the only file system that can really protect your content from silent data corruption.
