The process of files being corrupted as a consequence of some hardware or software failure is referred to as data corruption and this is one of the main problems that Internet hosting companies face because the larger a hard disk is and the more information is placed on it, the more likely it is for data to become corrupted. You'll find several fail-safes, but often the information becomes damaged silently, so neither the particular file system, nor the admins notice anything. As a result, a damaged file will be treated as a standard one and if the hard disk drive is part of a RAID, the file will be duplicated on all other disk drives. Theoretically, this is for redundancy, but in practice the damage will be even worse. When a file gets damaged, it will be partly or entirely unreadable, therefore 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, so you risk sacrificing your content. Although the most widespread server file systems have various checks, they quite often fail to discover a problem early enough or require a long time period to check all the files and the web server will not be operational in the meantime.

No Data Corruption & Data Integrity in Web Hosting

We have tackled the problem of silent data corruption on all our web hosting servers by using the state-of-the-art Z file system, or ZFS. The latter is superior to other file systems because it is the only one on the market that checks all 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 will be stored on several NVMe drives and frequently synchronized between them for redundancy. ZFS regularly compares the checksum of all files and if any file is detected as damaged, it's replaced promptly with a good copy from another disk. As this happens in real time, there's no risk that a damaged file may remain or may be copied on the remaining NVMes. ZFS needs a lot of physical memory to execute the real-time checks and the benefit of our cloud website hosting platform is that we employ multiple powerful servers working together. In case you host your Internet sites with us, your information will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be shielded from silent data corruption since all our storage servers use the state-of-the-art ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, to verify the integrity of each and every file. When you upload content to your account, it will be placed on a couple of redundant drives being employed in a RAID i.e. the files will be the same on all drives. All of the copies of a particular file will have the same checksum on all hard drives and ZFS will compare the checksums of the duplicates quickly, and if it identifies a mismatch, which would indicate that one of the copies is corrupted, it'll replace that file with a healthy copy from one of the other drives. Even if there is an unforeseen blackout, the data on the servers will not get corrupted and there will not be any need for a time-consuming system check that other file systems perform after some breakdown, prolonging the time needed for the server to return online. ZFS is the file system that can truly protect your content from silent data corruption.
