Data corruption is the unintentional transformation of a file or the losing of information that usually occurs during reading or writing. The reason can be hardware or software malfunction, and as a result, a file may become partially or completely corrupted, so it'll no longer work correctly since its bits will be scrambled or lacking. An image file, for example, will no longer present 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 such an issue appears and it isn't recognized by the system or by an admin, the data will be corrupted silently and when this happens on a drive that's a part of a RAID array where the data is synchronized between various drives, the corrupted file shall be copied on all of the other drives and the harm will become long term. Many frequently used file systems either do not offer real-time checks or do not have high quality ones that can detect an issue before the damage is done, so silent data corruption is a very common matter on web hosting servers where substantial volumes of data 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 shall be guaranteed by the ZFS file system which we use on our cloud platform. Most of the hosting suppliers, like our firm, use multiple hard drives to store content and because the drives work in a RAID, identical info is synchronized between the drives all the time. If a file on a drive gets corrupted for some reason, yet, it's very likely that it will be copied on the other drives since other file systems do not include special checks for this. In contrast to them, ZFS applies a digital fingerprint, or a checksum, for every file. In the event that a file gets corrupted, its checksum won't match what ZFS has as a record for it, so the bad copy shall be substituted with a good one from another hard drive. Because this happens right away, there is no possibility for any of your files to ever be corrupted.
No Data Corruption & Data Integrity in Semi-dedicated Servers
In case you purchase one of our semi-dedicated server plans, you will not need to be concerned about silent data corruption since we use ZFS - a high level file system which checks all the files in real time. Each time you upload a file to your 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 of 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 right away, so there will be no danger for any part of your content at any moment. In contrast, all of the other file systems execute checks after a system malfunction, but since they do not use anything similar to the checksums that ZFS uses, they can't detect silently corrupted files, so a corrupted copy can be replicated on the other disks as well and you could lose important info. Because this isn't the case with ZFS, we warrant the integrity of each file you upload no matter what.
