Data corruption is the unintentional change of a file or the loss of information that usually occurs during reading or writing. The reason can be hardware or software malfunction, and because of this, a file can become partially or completely corrupted, so it'll no longer function as it should because its bits will be scrambled or missing. An image file, for instance, will no longer present an authentic image, but a random combination of colors, an archive will be impossible to unpack because its content will be unreadable, etc. If this kind of an issue occurs and it is not found by the system or by an administrator, the data will get corrupted silently and in case this happens on a drive that's a part of a RAID array where the info is synced between various drives, the corrupted file will be replicated on all of the other drives and the harm will become long term. A number of commonly used file systems either do not have real-time checks or do not have high quality 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 Hosting

We warrant the integrity of the data uploaded in every hosting account which is generated on our cloud platform because we work with the advanced ZFS file system. The aforementioned is the only one which was designed to avoid silent data corruption using a unique checksum for each file. We shall store your info on multiple SSD drives which function in a RAID, so the same files will be available on several places simultaneously. ZFS checks the digital fingerprint of all of the files on all of the drives in real time and in the event that the checksum of any file differs from what it needs to be, the file system replaces that file with an undamaged version from another drive in the RAID. There's no other file system that uses checksums, so it is easy for data to be silently corrupted and the bad file to be duplicated on all drives with time, but since this can never happen on a server running ZFS, you will not have to concern yourself with the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Servers

In case you buy one of our semi-dedicated server plans, you won't need to worry about silent file corruption as we use ZFS - an advanced file system that monitors all files in real time. Each time you upload a file to your website hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This 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 when it detects a corrupted copy, it replaces it with a healthy one from another drive. This happens right away, so there will be no threat for any part of your content at any time. In comparison, other file systems execute checks only after a system breakdown, but since they do not use anything similar to the checksums which ZFS uses, they won't detect silently corrupted files, so a bad copy may be replicated on the other drives as well and you could lose precious info. Since this is not the case with ZFS, we're able to warrant the integrity of every single file you upload no matter what.
