Data corruption is the damage of info because of various hardware or software failures. When a file is damaged, it will no longer work properly, so an application will not start or shall give errors, a text file shall be partially or fully unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of data getting harmed without any identification by the system or an administrator, that makes it a serious problem for hosting servers as failures are much more likely to happen on larger hard disks where substantial volumes of information are located. When a drive is a part of a RAID and the info on it is replicated on other drives for redundancy, it is likely that the damaged file will be treated as an undamaged one and it will be copied on all the drives, making the damage permanent. Lots of the file systems that operate on web servers nowadays often are not able to discover corrupted files right away or they need time-consuming system checks through which the server is not working.

No Data Corruption & Data Integrity in Web Hosting

We warrant the integrity of the info uploaded in each web hosting account that is generated on our cloud platform since we work with the advanced ZFS file system. The latter is the only one which was designed to prevent silent data corruption using a unique checksum for each file. We shall store your data on a number of NVMe drives that operate in a RAID, so exactly the same files will exist on several places simultaneously. ZFS checks the digital fingerprint of all the files on all drives in real time and in case the checksum of any file differs from what it should be, the file system swaps that file with a healthy version from some other drive from the RAID. There's no other file system which uses checksums, so it's possible for data to be silently corrupted and the bad file to be reproduced on all drives over time, but since this can never happen on a server using ZFS, you don't have to concern yourself with the integrity of your data.

No Data Corruption & Data Integrity in Semi-dedicated Servers

In case you go for one of our semi-dedicated server solutions, you won't have to worry about silent data corruption as we use ZFS - an advanced file system that checks all 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. The file will be synchronized between a number of NVMe 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 if it detects a damaged copy, it replaces it with a healthy one from another drive. This is done right away, so there will be no danger for any part of your content at any moment. In contrast, other file systems carry out checks after a system malfunction, but since they don't use anything similar to the checksums which ZFS uses, they won't detect silently corrupted files, so a bad copy could be replicated on the remaining disks as well and you may lose precious information. As this isn't the case with ZFS, we're able to warrant the integrity of each and every file you upload no matter what.
