Data corruption is the damage of information caused by various hardware or software fails. The moment a file gets damaged, it will no longer function as it should, so an application will not start or will give errors, a text file can be partially or completely unreadable, an archive file will be impossible to open and unpack, etc. Silent data corruption is the process of info getting damaged without any identification by the system or an admin, which makes it a significant problem for web hosting servers as fails are much more likely to occur on bigger hard drives where significant volumes of info are located. If a drive is a part of a RAID and the data on it is replicated on other drives for redundancy, it's more than likely that the bad file will be treated as an ordinary one and it'll be copied on all drives, making the damage permanent. Lots of the file systems which run on web servers these days often cannot identify corrupted files in real time or they need time-consuming system checks through which the server is not working.

No Data Corruption & Data Integrity in Cloud Hosting

We warrant the integrity of the information uploaded in every single cloud hosting account that is generated on our cloud platform because we use the advanced ZFS file system. The latter is the only one that was designed to prevent silent data corruption thanks to a unique checksum for each file. We will store your information on a number of NVMe drives which function in a RAID, so the same files will be present on several places simultaneously. ZFS checks the digital fingerprint of all the files on all drives in real time and if the checksum of any file differs from what it should be, the file system replaces that file with an undamaged version from another drive within the RAID. There's no other file system which uses checksums, so it is easy for data to be silently damaged and the bad file to be reproduced on all drives over time, but since this can never happen on a server using ZFS, you won't have to concern yourself with the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

If you obtain one of our semi-dedicated hosting plans, you won't have to worry about silent file corruption because we use ZFS - a high level file system that keeps track of all of the files in real time. Each time you upload a file to your hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synced between several NVMe drives for redundancy, so if a drive fails, the other ones will take control. ZFS compares the checksum of all of 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 immediately, so there will be no threat for any part of your content at any moment. In contrast, alternative file systems perform checks after a system failure, but since they do not use anything similar to the checksums that ZFS uses, they are unable to detect silently corrupted files, so a bad copy could be replicated on the remaining disks as well and you can lose important information. Because this is not the case with ZFS, we're able to guarantee the integrity of each file you upload no matter what.
