Data corruption is the damage of info because of various hardware or software problems. The moment a file is corrupted, it will no longer function as it should, so an app will not start or shall give errors, a text file could be partially or fully unreadable, an archive file will be impossible to open and unpack, etc. Silent data corruption is the process of info getting harmed without any acknowledgement by the system or an administrator, which makes it a significant problem for web hosting servers as problems are much more likely to happen on larger in size hard drives where substantial volumes of information are placed. In case a drive is part of a RAID and the information on it is duplicated on other drives for redundancy, it is likely that the bad file will be treated as a regular one and it'll be copied on all drives, making the damage permanent. A huge number of the file systems that operate on web servers today often cannot detect corrupted files instantly or they need time-consuming system checks during which the server is not operational.

No Data Corruption & Data Integrity in Hosting

We guarantee the integrity of the information uploaded in each and every hosting account which is made on our cloud platform since we employ the advanced ZFS file system. The latter is the only one which was designed to prevent silent data corruption using a unique checksum for each and every file. We shall store your info on multiple NVMe drives which function in a RAID, so exactly the same files will be available on several places at the same time. 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 swaps that file with an undamaged copy from a different drive inside the RAID. There's no other file system which uses checksums, so it is easy for data to get silently corrupted and the bad file to be reproduced on all drives over time, but since that can never happen on a server using ZFS, you don't have to worry about the integrity of your information.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We've avoided any chance of files getting corrupted silently due to the fact that the servers where your semi-dedicated hosting account will be created work with a powerful file system named ZFS. Its key advantage over alternative file systems is that it uses a unique checksum for each and every file - a digital fingerprint which is checked in real time. As we keep all content on multiple NVMe drives, ZFS checks whether the fingerprint of a file on one drive corresponds to the one on the other drives and the one it has stored. In the event that there is a mismatch, the corrupted copy is replaced with a good one from one of the other drives and because it happens right away, there is no chance that a damaged copy could remain on our hosting servers or that it can be copied to the other hard disks in the RAID. None of the other file systems work with this type of checks and furthermore, even during a file system check following a sudden power failure, none of them will discover silently corrupted files. In comparison, ZFS won't crash after a power loss and the constant checksum monitoring makes a lenghty file system check obsolete.
