Data corruption is the unintentional transformation of a file or the losing of information which often occurs during reading or writing. The reason may be hardware or software malfunction, and due to this fact, a file can become partially or completely corrupted, so it will no longer work properly as its bits shall be scrambled or lost. An image file, for example, will no longer display a true image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, etc. In the event that this kind of an issue occurs and it is not identified by the system or by an admin, the data will be corrupted silently and when this happens on a drive which is a part of a RAID array where the info is synchronized between different drives, the corrupted file will be copied on all of the other drives and the harm will become long term. A number of popular file systems either don't have real-time checks or do not have good ones which will detect an issue before the damage is done, so silent data corruption is a common matter on web hosting servers where substantial amounts of data are stored.
No Data Corruption & Data Integrity in Shared Web Hosting
The integrity of the data which you upload to your new shared web hosting
account shall be guaranteed by the ZFS file system which we employ on our cloud platform. Most of the hosting service providers, including our company, use multiple hard disks to store content and because the drives work in a RAID, exactly the same data is synchronized between the drives all the time. If a file on a drive becomes corrupted for whatever reason, yet, it's likely that it will be reproduced on the other drives since other file systems don't offer special checks for this. In contrast to them, ZFS employs a digital fingerprint, or a checksum, for each and every file. In case a file gets corrupted, its checksum will not match what ZFS has as a record for it, therefore the bad copy shall be substituted with a good one from a different drive. As this happens immediately, there's no possibility for any of your files to ever get damaged.
No Data Corruption & Data Integrity in Semi-dedicated Servers
In case you acquire one of our semi-dedicated server
solutions, you won't need to be concerned about silent data corruption because we use ZFS - an advanced file system that checks all the 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. That file will be synced between multiple SSD drives for redundancy, so if one drive fails, the other ones will take control. ZFS compares the checksum of all copies on the different drives and when it detects a damaged copy, it replaces it with a healthy one from a different drive. This happens immediately, so there will be no threat for any part of your content at any moment. In contrast, all of the other file systems perform checks after a system malfunction, but since they don't use anything similar to the checksums which ZFS uses, they will not detect silently corrupted files, so a corrupted copy can be replicated on the remaining drives as well and you may lose critical information. Since this isn't the case with ZFS, we're able to guarantee the integrity of every single file you upload no matter what.
