Data corruption is the unintentional modification of a file or the losing of information that usually occurs during reading or writing. The reason may be hardware or software failure, and as a consequence, a file could become partially or completely corrupted, so it'll no longer work properly since its bits will be scrambled or missing. An image file, for example, will no longer show an authentic image, but a random mix of colors, an archive will be impossible to unpack since its content will be unreadable, etc. If such an issue appears and it isn't noticed by the system or by an admin, the data will get corrupted silently and in case this happens on a drive which is part of a RAID array where the information is synchronized between different drives, the corrupted file shall be duplicated on all the other drives and the harm will be permanent. Many frequently used file systems either do not feature real-time checks or don't have high quality ones that can detect a problem before the damage is done, so silent data corruption is a very common matter on internet hosting servers where huge amounts of information are kept.
No Data Corruption & Data Integrity in Cloud Website Hosting
The integrity of the data that you upload to your new cloud website hosting account will be ensured by the ZFS file system that we employ on our cloud platform. Most hosting service providers, like our firm, use multiple HDDs to keep content and because the drives work in a RAID, the same info is synchronized between the drives at all times. When a file on a drive gets damaged for reasons unknown, however, it is more than likely that it will be reproduced on the other drives because other file systems do not have special checks for this. In contrast to them, ZFS applies a digital fingerprint, or a checksum, for every file. In case a file gets corrupted, its checksum will not match what ZFS has as a record for it, and the damaged copy will be replaced with a good one from another hard disk. Due to the fact that this happens instantly, there's no risk for any of your files to ever get damaged.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
If you buy one of our semi-dedicated hosting packages, you won't need to be concerned about silent data corruption because we use ZFS - an advanced file system that checks all of 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. The file will be synced between several SSD drives for redundancy, so if a 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 in real time, so there will be no threat for any part of your content at any time. By comparison, all of the other file systems perform checks only after a system malfunction, but since they do not use anything similar to the checksums that ZFS uses, they are unable to detect silently corrupted files, so a corrupted copy could be replicated on the remaining drives as well and you may lose critical info. As this is not the case with ZFS, we're able to warrant the integrity of each and every file you upload no matter what.
