The process of files being corrupted as a result of some hardware or software failure is called data corruption and this is among the main problems which Internet hosting companies face because the larger a hard drive is and the more data is kept on it, the much more likely it is for data to be corrupted. There are a couple of fail-safes, still often the data is corrupted silently, so neither the file system, nor the admins see a thing. Because of this, a damaged file will be handled as a good one and if the hard disk drive is a part of a RAID, that particular file will be copied on all other disk drives. Theoretically, this is done for redundancy, but in practice the damage will get even worse. Once a file gets damaged, it will be partially or fully unreadable, therefore a text file will no longer be readable, an image file will present a random blend of colors in case it opens at all and an archive shall be impossible to unpack, so you risk sacrificing your site content. Although the most well-known server file systems include various checks, they often fail to discover some problem early enough or require a vast amount of time to be able to check all of the files and the web server will not be operational in the meantime.
No Data Corruption & Data Integrity in Shared Hosting
In case you host your websites in a shared hosting account with our company, you won't need to worry about any of your data ever getting damaged. We can ensure that due to the fact that our cloud hosting platform uses the leading-edge ZFS file system. The aforementioned is the only file system that uses checksums, or unique digital fingerprints, for each and every file. Any information that you upload will be saved in a RAID i.e. simultaneously on numerous NVMe drives. All the file systems synchronize the files between the different drives using such a setup, but there's no real guarantee that a file won't be corrupted. This could occur during the writing process on any drive and after that a corrupted copy can be copied on the other drives. What is different on our platform is that ZFS analyzes the checksums of all files on all the drives right away and when a corrupted file is found, it is substituted with a good copy with the correct checksum from some other drive. This way, your info will continue to be intact no matter what, even if a whole drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
If you get one of our semi-dedicated hosting solutions, you will not have to worry about silent data corruption because we use ZFS - an advanced file system which checks all the files in real time. Every time you upload a file to your website hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synced between multiple NVMe drives for redundancy, so if a drive fails, the other ones will take over. ZFS compares the checksum of all copies on the different drives and when it detects a corrupted copy, it replaces it with a healthy one from a different drive. This happens instantly, so there will be no threat for any part of your content at any time. By comparison, alternative file systems carry out checks after a system malfunction, but since they don't use anything similar to the checksums that ZFS uses, they won't detect silently corrupted files, so a bad copy could be replicated on the rest of the disks as well and you could lose precious information. As this isn't the case with ZFS, we can guarantee the integrity of every single file you upload no matter what.
