Data corruption is the damage of information because of various software or hardware failures. The moment a file gets corrupted, it will no longer function correctly, so an application will not start or will give errors, a text file could be partially or entirely unreadable, an archive file will be impossible to open and 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 serious problem for hosting servers as problems are very likely to happen on larger hard disks where substantial volumes of information are placed. In case a drive is a part of a RAID and the data on it is replicated on other drives for redundancy, it is likely that the damaged file will be treated as a good one and it'll be duplicated on all of the drives, making the damage permanent. A lot of the file systems that run on web servers nowadays often are not able to identify corrupted files instantly or they need time-consuming system checks during which the server is not working.

No Data Corruption & Data Integrity in Cloud Web Hosting

We guarantee the integrity of the data uploaded in every cloud web hosting account that is made on our cloud platform because we use the advanced ZFS file system. The aforementioned is the only one that was designed to prevent silent data corruption using a unique checksum for each and every file. We shall store your information on a number of NVMe drives which work in a RAID, so the same files will be present on several places simultaneously. ZFS checks the digital fingerprint of all of the files on all the drives in real time and in the event that the checksum of any file differs from what it has to be, the file system swaps that file with an undamaged version from a different drive from the RAID. There's no other file system that uses checksums, so it is possible for data to get silently damaged and the bad file to be replicated on all drives over time, but since this can never happen on a server using ZFS, you will not have to concern yourself with the integrity of your data.
