The process of files getting corrupted resulting from some hardware or software failure is known as data corruption and this is among the main problems which web hosting companies face because the larger a hard disk is and the more info is filed on it, the more likely it is for data to become corrupted. You will find various fail-safes, yet often the information gets damaged silently, so neither the particular file system, nor the admins see a thing. Because of this, a damaged file will be treated as a good one and if the hard drive is a part of a RAID, that file will be copied on all other disk drives. In theory, this is done for redundancy, but in reality the damage will get worse. The moment a file gets damaged, it will be partly or fully unreadable, so a text file will no longer be readable, an image file will show a random mix of colors if it opens at all and an archive will be impossible to unpack, so you risk losing your website content. Although the most popular server file systems feature various checks, they frequently fail to detect some problem early enough or require an extensive period of time to be able to check all files and the web server will not be functional for the time being.
No Data Corruption & Data Integrity in Shared Hosting
If you host your Internet sites in a shared hosting account from our firm, you don't have to worry about any of your data ever getting damaged. We can guarantee that due to the fact that our cloud hosting platform works with the amazing ZFS file system. The aforementioned is the only file system which works with checksums, or unique digital fingerprints, for each and every file. All of the information that you upload will be stored in a RAID i.e. simultaneously on many different NVMes. All file systems synchronize the files between the different drives with this type of a setup, but there's no real warranty that a file won't get corrupted. This could occur at the time of the writing process on each drive and then a bad copy can be copied on all other drives. What makes the difference on our platform is the fact that ZFS analyzes the checksums of all files on all drives in real time and in the event that a corrupted file is found, it's substituted with a good copy with the correct checksum from another 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 Servers
In case you purchase one of our semi-dedicated server packages, you will not need to worry about silent file corruption since we use ZFS - an advanced file system that monitors all of the files in real time. Whenever 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 a couple of 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 if it detects a corrupted copy, it replaces it with a healthy one from another drive. This happens instantly, so there will be no risk for any part of your content at any moment. By comparison, alternative file systems carry out checks only after a system breakdown, but since they do not use anything similar to the checksums that ZFS uses, they won't detect silently corrupted files, so a corrupted copy could be replicated on the rest of the drives as well and you may lose precious data. Since this isn't the case with ZFS, we are able to guarantee the integrity of each file you upload no matter what.
