Data corruption is the damage of info because of various hardware or software failures. After a file gets corrupted, it will no longer work properly, so an app will not start or shall give errors, a text file shall be partially or entirely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of information getting harmed without any identification by the system or an admin, which makes it a significant problem for hosting servers as problems are more likely to occur on larger hard disks where substantial volumes of info are stored. When a drive is a part of a RAID and the info on it is copied on other drives for redundancy, it's likely that the damaged file will be treated as a regular one and will be copied on all of the drives, making the harm permanent. Lots of the file systems that run on web servers these days often are not able to locate corrupted files immediately or they need time-consuming system checks through which the server isn't functioning.

No Data Corruption & Data Integrity in Cloud Hosting

We guarantee the integrity of the information uploaded in any cloud hosting account which is created on our cloud platform as we use the advanced ZFS file system. The latter is the only one that was designed to avoid silent data corruption through a unique checksum for each and every file. We will store your info on multiple SSD drives which work in a RAID, so exactly the same files will exist 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 has to be, the file system swaps that file with an undamaged version from another drive inside the RAID. No other file system uses checksums, so it's easy for data to become silently corrupted and the bad file to be reproduced on all drives with time, but since this can never happen on a server using ZFS, you do not have to concern yourself with the integrity of your information.

No Data Corruption & Data Integrity in Semi-dedicated Servers

In case you go for one of our semi-dedicated server plans, you will not need to be concerned about silent file corruption because we use ZFS - a high level file system which checks all of the files in real time. Every 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 synchronized between several SSD 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 corrupted copy, it replaces it with a healthy one from a different drive. This is done instantly, so there will be no threat for any part of your content at any time. In comparison, all of the other file systems carry out 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 can be replicated on the remaining disks as well and you can lose crucial information. As this is not the case with ZFS, we can guarantee the integrity of every single file you upload no matter what.
