The process of files being corrupted because of some hardware or software failure is referred to as data corruption and this is one of the main problems that hosting companies face since the larger a hard disk drive is and the more info is filed on it, the much more likely it is for data to be corrupted. You will find several fail-safes, still often the data gets damaged silently, so neither the particular file system, nor the admins see anything. Thus, a damaged file will be treated as a regular one and if the HDD is part of a RAID, that particular file will be duplicated on all other drives. In principle, this is done for redundancy, but in reality the damage will be worse. Once some file gets damaged, it will be partly or fully unreadable, so a text file will no longer be readable, an image file will present a random blend of colors if it opens at all and an archive shall be impossible to unpack, so you risk losing your website content. Although the most widely used server file systems feature various checks, they are likely to fail to detect some problem early enough or require a long time period in order to check all of the files and the web hosting server will not be functional in the meantime.

No Data Corruption & Data Integrity in Hosting

In case you host your websites in a hosting account from our company, you don't have to worry about your data ever getting corrupted. We can ensure that as our cloud hosting platform works with the revolutionary ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for each file. Any kind of data that you upload will be kept in a RAID i.e. simultaneously on a large number of NVMe drives. All of the file systems synchronize the files between the different drives with this type of a setup, but there's no real guarantee that a file won't get corrupted. This can happen during the writing process on any drive and then a corrupted copy can be copied on the other drives. What is different on our platform is the fact that ZFS compares the checksums of all files on all drives in real time and if a corrupted file is found, it's substituted with a good copy with the correct checksum from some other drive. By doing this, your information will continue to be unharmed no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

If you go for one of our semi-dedicated hosting plans, you will not need to be concerned about silent file corruption because we use ZFS - a high level file system that monitors all files in real time. Whenever you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synced between several NVMe drives for redundancy, so if one drive fails, the other ones will take over. ZFS compares the checksum of all the copies on the different drives and in case it detects a damaged copy, it replaces it with a healthy one from another drive. This is done right away, so there will be no threat for any part of your content at any time. In comparison, all the other file systems perform checks after a system malfunction, but since they do not use anything similar to the checksums that ZFS uses, they will not detect silently corrupted files, so a bad copy may be replicated on the other disks as well and you may lose important data. Since this is not the case with ZFS, we are able to guarantee the integrity of each file you upload no matter what.
