The process of files being damaged due to some hardware or software failure is referred to as data corruption and this is among the main problems which hosting companies face as the larger a hard disk drive is and the more info is filed on it, the much more likely it is for data to get corrupted. There're various fail-safes, but often the info is damaged silently, so neither the file system, nor the admins detect a thing. Because of this, a bad file will be treated as a good one and if the hard drive is part of a RAID, the file will be duplicated on all other drives. Theoretically, this is for redundancy, but in practice the damage will be even worse. The moment some file gets corrupted, it will be partially or fully unreadable, so 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 sacrificing your website content. Although the most well-known server file systems have various checks, they quite often fail to discover some problem early enough or require an extensive time period to be able to check all the files and the hosting server will not be operational in the meantime.

No Data Corruption & Data Integrity in Cloud Hosting

We have dealt with the issue of silent data corruption on our cloud hosting servers by using the state-of-the-art Z file system, or ZFS. The latter is more advanced than other file systems because it is the only one out there that checks all the files instantly by employing a checksum - a digital identifier which is unique for each file. When you upload content to your account, it will be stored on several NVMe drives and continually synchronized between them for redundancy. ZFS regularly compares the checksum of all files and if any file is detected as damaged, it is replaced instantly 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 requires a lot of physical memory in order to perform the real-time checks and the benefit of our cloud hosting platform is that we work with multiple very powerful servers working together. If you host your Internet sites 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 shielded from silent data corruption as all of our storage servers use the effective ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, to ensure the integrity of each file. When you upload content to your account, it will be saved on several redundant drives employed in a RAID i.e. the files shall be the same across all disk drives. All of the copies of a specific file will feature the same checksum on all hard drives and ZFS will compare the checksums of the duplicates in real time, so if it discovers a mismatch, that will indicate that one of the copies is corrupted, it will replace that file with a healthy copy from one of the other drives. Even if there's a sudden power loss, the data on the servers won't become corrupted and there won't be any need for a time-consuming system check which other file systems perform following some breakdown, lengthening the time needed for the server to return online. ZFS is the file system which can truly protect your content from silent data corruption.
