Data corruption is the damage of information due to various software or hardware problems. The moment a file gets damaged, it will no longer work as it should, so an application will not start or shall give errors, a text file could be partially or entirely unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of info getting damaged without any acknowledgement by the system or an admin, that makes it a significant problem for hosting servers as failures are very likely to occur on bigger hard disks where considerable volumes of info are located. When a drive is a part of a RAID and the information on it is duplicated on other drives for redundancy, it is more than likely that the bad file will be treated as a healthy one and it'll be copied on all drives, making the damage permanent. Lots of the file systems which operate on web servers nowadays often are unable to find corrupted files instantly or they need time-consuming system checks through which the server is not working.

No Data Corruption & Data Integrity in Cloud Hosting

We guarantee the integrity of the data uploaded in every cloud hosting account which is generated on our cloud platform since we work with the advanced ZFS file system. The aforementioned is the only one that was designed to avoid silent data corruption through a unique checksum for each file. We shall store your information on multiple NVMe drives that work in a RAID, so the exact same files will be present on several places simultaneously. ZFS checks the digital fingerprint of all of the files on all drives in real time and if the checksum of any file is different from what it should be, the file system swaps that file with a healthy copy from another drive inside the RAID. There's no other file system that uses checksums, so it is possible for data to be silently corrupted and the bad file to be replicated on all drives with time, but since this can never happen on a server running ZFS, you do not have to worry about the integrity of your data.
