Data corruption is the damage of information due to various hardware or software problems. The moment a file gets corrupted, it will no longer function as it should, so an application will not start or will give errors, a text file will be partially or fully unreadable, an archive file will be impossible to open and unpack, etc. Silent data corruption is the process of information getting damaged without any identification by the system or an administrator, that makes it a significant problem for hosting servers as fails are more likely to occur on bigger hard drives where large volumes of info are located. If a drive is part of a RAID and the data on it is replicated on other drives for redundancy, it's more than likely that the damaged file will be treated as an undamaged one and will be duplicated on all the drives, making the damage permanent. A huge number of the file systems which run on web servers today often cannot recognize corrupted files right away or they need time-consuming system checks during which the server is not functioning.

No Data Corruption & Data Integrity in Hosting

We warrant the integrity of the information uploaded in each and every hosting account which is generated on our cloud platform due to the fact that we use the advanced ZFS file system. The aforementioned is the only one which was designed to avert silent data corruption via a unique checksum for each and every file. We shall store your data on multiple NVMe drives that function in a RAID, so exactly the same files will exist on several places at once. ZFS checks the digital fingerprint of all of 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 replaces that file with a healthy version from a different drive inside the RAID. No other file system uses checksums, so it is possible for data to become silently corrupted and the bad file to be reproduced on all drives over time, but since this can never happen on a server running ZFS, you do not have to concern yourself with the integrity of your info.
