The process of files being damaged as a result of some hardware or software failure is known as data corruption and this is one of the main problems that Internet hosting companies face as the larger a hard drive is and the more information is filed on it, the much more likely it is for data to become corrupted. You will find various fail-safes, but often the info is damaged silently, so neither the particular file system, nor the admins notice anything. As a result, a bad file will be treated as a standard one and if the hard drive is part of a RAID, the file will be duplicated on all other drives. In theory, this is for redundancy, but in practice the damage will get even worse. The moment some file gets damaged, it will be partially or entirely unreadable, therefore a text file will no longer be readable, an image file will display a random combination of colors if it opens at all and an archive shall be impossible to unpack, and you risk sacrificing your website content. Although the most well-known server file systems include various checks, they are likely to fail to find some problem early enough or require a long time period in order to check all files and the server will not be operational in the meantime.

No Data Corruption & Data Integrity in Shared Hosting

In case you host your Internet sites in a shared hosting account with our firm, you don't have to worry about your data ever getting corrupted. We can guarantee that because our cloud hosting platform employs the state-of-the-art ZFS file system. The aforementioned is the only file system which works with checksums, or unique digital fingerprints, for every single file. Any data that you upload will be kept in a RAID i.e. simultaneously on multiple NVMes. All file systems synchronize the files between the separate drives with such a setup, but there is no real guarantee that a file will not be corrupted. This could happen during the writing process on each drive and after that a damaged copy may be copied on the rest of the drives. What makes the difference on our platform is the fact that ZFS examines the checksums of all files on all of the drives instantly and in the event that a corrupted file is found, it is substituted with a good copy with the correct checksum from some other drive. By doing this, your data will remain undamaged no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

If you obtain one of our semi-dedicated hosting packages, you won't have to worry about silent file corruption as we use ZFS - a high level file system which keeps track of all files in real time. Each time you upload a file to your web hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synchronized between multiple NVMe drives for redundancy, so if a drive fails, the other ones will take control. ZFS compares the checksum of all copies on the different drives and in case it detects a damaged copy, it replaces it with a healthy one from a different drive. This happens right away, so there will be no threat for any part of your content at any time. In contrast, other file systems execute checks after a system failure, but since they do not use anything similar to the checksums which ZFS uses, they cannot detect silently corrupted files, so a corrupted copy may be replicated on the remaining disks as well and you may lose important data. Since this is not the case with ZFS, we're able to warrant the integrity of each file you upload no matter what.
