Data corruption is the damage of data caused by various software or hardware problems. The moment a file is damaged, it will no longer function as it should, so an app will not start or will give errors, a text file shall be partially or entirely unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of information getting damaged without any acknowledgement by the system or an admin, that makes it a significant problem for hosting servers as problems are more likely to happen on larger hard drives where considerable volumes of information are stored. If a drive is a part of a RAID and the info on it is duplicated on other drives for redundancy, it's very likely that the damaged file will be treated as a healthy one and will be copied on all of the drives, making the harm permanent. A lot of the file systems which run on web servers these days often are not able to recognize corrupted files right away or they need time-consuming system checks during which the server is not functioning.

No Data Corruption & Data Integrity in Shared Hosting

We warrant the integrity of the data uploaded in every single shared hosting account which is generated on our cloud platform due to the fact that we work with the advanced ZFS file system. The latter is the only one which was designed to prevent silent data corruption via a unique checksum for each and every file. We will store your info on a number of NVMe drives which operate in a RAID, so the same files will exist on several places at the same time. ZFS checks the digital fingerprint of all files on all the drives in real time and in the event that the checksum of any file is different from what it should be, the file system replaces that file with an undamaged copy from another drive inside the RAID. No other file system uses checksums, so it's possible for data to be silently damaged and the bad file to be reproduced on all drives with time, but since this 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 Servers

If you obtain one of our semi-dedicated server solutions, you will not have to be concerned about silent data corruption because we use ZFS - a high level file system that checks all the files in real time. Whenever you upload a file to your web hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synchronized between a couple of NVMe drives for redundancy, so if one drive fails, the other ones will take over. ZFS compares the checksum of all the copies on the different drives and when it detects a corrupted copy, it replaces it with a healthy one from another drive. This is done instantly, so there will be no danger for any part of your content at any moment. In comparison, alternative file systems perform checks after a system failure, but since they do not use anything similar to the checksums which ZFS uses, they won't detect silently corrupted files, so a corrupted copy may be replicated on the other drives as well and you can lose crucial data. Because this is not the case with ZFS, we are able to guarantee the integrity of every single file you upload no matter what.
