Data corruption is the unintentional transformation of a file or the loss of information which usually occurs during reading or writing. The reason can be hardware or software fail, and due to this fact, a file may become partially or entirely corrupted, so it'll no longer function correctly as its bits will be scrambled or lacking. An image file, for example, will no longer present a true image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, and so on. In case such an issue occurs and it's not noticed by the system or by an admin, the data will become corrupted silently and in case this happens on a drive that's 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 permanent. A large number of popular file systems either don't offer real-time checks or don't have high quality ones that will detect a problem before the damage is done, so silent data corruption is a common problem on web hosting servers where substantial amounts of information are stored.

No Data Corruption & Data Integrity in Web Hosting

We warrant the integrity of the info uploaded in each and every web hosting account which is created on our cloud platform since we employ the advanced ZFS file system. The aforementioned is the only one that was designed to avert silent data corruption through a unique checksum for each file. We shall store your info on a large number of NVMe drives which function in a RAID, so identical files will be available on several places simultaneously. ZFS checks the digital fingerprint of all files on all of the drives in real time and if the checksum of any file differs from what it should be, the file system swaps that file with a healthy copy from a different drive from the RAID. There's no other file system which uses checksums, so it's possible for data to be silently damaged and the bad file to be reproduced on all drives over time, but since that can never happen on a server running ZFS, you don't have to worry about the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

If you buy one of our semi-dedicated hosting plans, you won't have to worry about silent data corruption as we use ZFS - a high level file system that monitors all files in real time. Whenever 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 synchronized between a couple of NVMe drives for redundancy, so if one drive fails, the other ones will take control. ZFS compares the checksum of all the 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 in real time, so there will be no threat for any part of your content at any moment. By comparison, all of the other file systems carry out checks after a system malfunction, but since they do not use anything similar to the checksums which ZFS uses, they cannot detect silently corrupted files, so a corrupted copy could be replicated on the remaining disks as well and you may lose critical info. As this isn't the case with ZFS, we are able to guarantee the integrity of every single file you upload no matter what.
