The process of files being damaged caused by some hardware or software failure is referred to as data corruption and this is among the main problems that Internet hosting companies face as the larger a hard drive is and the more data is stored on it, the much more likely it is for data to get corrupted. You'll find different fail-safes, still often the data is damaged silently, so neither the particular file system, nor the admins notice a thing. Thus, a damaged file will be handled as a standard one and if the hard drive is part of a RAID, that file will be duplicated on all other disk drives. In theory, this is for redundancy, but in practice the damage will get worse. When a file gets corrupted, it will be partially or fully unreadable, so a text file will not be readable, an image file will display a random blend of colors if it opens at all and an archive will be impossible to unpack, so you risk sacrificing your content. Although the most frequently used server file systems feature various checks, they frequently fail to find some problem early enough or require an extensive amount of time to be able to check all of the files and the web hosting server will not be functional for the time being.
No Data Corruption & Data Integrity in Cloud Hosting
The integrity of the data that you upload to your new cloud hosting account shall be guaranteed by the ZFS file system which we take advantage of on our cloud platform. The vast majority of internet hosting service providers, like our firm, use multiple hard disks to store content and because the drives work in a RAID, the exact same data is synchronized between the drives at all times. When a file on a drive gets corrupted for reasons unknown, yet, it's more than likely that it will be duplicated on the other drives since alternative file systems don't offer special checks for this. In contrast to them, ZFS works with a digital fingerprint, or a checksum, for every file. In case a file gets damaged, its checksum will not match what ZFS has as a record for it, so the damaged copy will be replaced with a good one from another hard drive. Since this happens in real time, there's no possibility for any of your files to ever get damaged.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
If you purchase one of our semi-dedicated hosting solutions, you won't need to worry about silent file corruption since we use ZFS - an advanced file system which monitors all of the files in real time. Every time you upload a file to your web hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synchronized between multiple NVMe drives for redundancy, so if one 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 another drive. This happens in real time, so there will be no danger for any part of your content at any moment. In comparison, all the other file systems perform checks after a system breakdown, but since they don't use anything similar to the checksums which ZFS uses, they are unable to detect silently corrupted files, so a bad copy can be replicated on the remaining disks as well and you may lose crucial information. Since this is not the case with ZFS, we are able to warrant the integrity of every single file you upload no matter what.
