Data corruption is the damage of information because of various hardware or software fails. The moment a file is damaged, it will no longer work accurately, 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 then unpack, etc. Silent data corruption is the process of data getting harmed without any acknowledgement by the system or an administrator, which makes it a significant problem for hosting servers as fails are more likely to happen on larger hard disks where considerable volumes of info are placed. If a drive is 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 good one and it will be copied on all of the drives, making the damage permanent. A huge number of the file systems that run on web servers today often are unable to discover corrupted files instantly or they need time-consuming system checks through which the server is not working.

No Data Corruption & Data Integrity in Web Hosting

We guarantee the integrity of the info uploaded in each and every 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 that was designed to prevent silent data corruption thanks to a unique checksum for every single file. We shall store your data on a large number of NVMe drives that operate in a RAID, so the very same files will exist on several places concurrently. ZFS checks the digital fingerprint of all files on all drives in real time and in the event that the checksum of any file differs from what it should be, the file system swaps that file with an undamaged copy from another drive within the RAID. No other file system uses checksums, so it is possible for data to get silently damaged and the bad file to be reproduced on all drives over time, but since that can never happen on a server using ZFS, you do not have to worry about the integrity of your info.
