Data corruption is the damage of data caused by various hardware or software problems. When a file is damaged, it will no longer function accurately, so an application will not start or will give errors, a text file will be partially or entirely unreadable, an archive 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, that makes it a significant problem for website hosting servers as failures are much more likely to happen on larger hard drives where vast volumes of information are kept. In case a drive is part of a RAID and the information on it is replicated on other drives for redundancy, it's more than likely that the bad file will be treated as a good one and will be duplicated on all drives, making the damage permanent. A lot of the file systems that operate on web servers these days often cannot recognize corrupted files instantly or they need time-consuming system checks during which the server is not functioning.

No Data Corruption & Data Integrity in Website Hosting

We warrant the integrity of the information uploaded in every website hosting account which is generated on our cloud platform as we work with the advanced ZFS file system. The latter is the only one which was designed to avoid silent data corruption through a unique checksum for every single file. We shall store your info on multiple NVMe drives which function in a RAID, so the exact same files will be present on several places at the same time. ZFS checks the digital fingerprint of all of the files on all the 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 copy from some other drive from the RAID. There's no other file system which uses checksums, so it is possible 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 will not have to worry about the integrity of your data.
