Data corruption is the unintended change of a file or the loss of information which usually occurs during reading or writing. The reason could be hardware or software fail, and as a result, a file may become partially or fully corrupted, so it will no longer work as it should because its bits shall be scrambled or lacking. An image file, for example, will no longer show an accurate image, but a random combination of colors, an archive will be impossible to unpack as its content will be unreadable, etcetera. In case such a problem appears and it's not identified by the system or by an administrator, the data will get corrupted silently and in case this happens on a drive which is a part of a RAID array where the info is synced between different drives, the corrupted file will be copied on all other drives and the harm will become long term. A number of popular file systems either do not feature real-time checks or do not have good ones that can detect a problem before the damage is done, so silent data corruption is a very common matter on web hosting servers where huge volumes of data are stored.

No Data Corruption & Data Integrity in Shared Hosting

The integrity of the data that you upload to your new shared hosting account will be ensured by the ZFS file system which we make use of on our cloud platform. The vast majority of internet hosting providers, like our company, use multiple hard drives to store content and considering that the drives work in a RAID, the same info is synchronized between the drives all of the time. In case a file on a drive becomes corrupted for some reason, yet, it's very likely that it will be duplicated on the other drives because other file systems do not feature special checks for this. Unlike them, ZFS works with a digital fingerprint, or a checksum, for every single file. In the event that a file gets corrupted, its checksum won't match what ZFS has as a record for it, and the damaged copy will be substituted with a good one from a different hard disk drive. Because this happens instantly, there's no risk for any of your files to ever be corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Servers

If you go for one of our semi-dedicated server solutions, you won't have to be concerned about silent data corruption as we use ZFS - a high level file system that checks all the files in real time. Whenever you upload a file to your hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synchronized between a number of 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 if it detects a corrupted 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, alternative file systems perform checks only after a system failure, but since they don't use anything similar to the checksums that ZFS uses, they will not detect silently corrupted files, so a bad copy could be replicated on the other drives as well and you can lose critical info. Because this is not the case with ZFS, we can guarantee the integrity of each and every file you upload no matter what.
