Data corruption is the damage of data due to various hardware or software problems. After a file is corrupted, it will no longer function properly, so an app will not start or shall give errors, a text file shall be partially or completely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of info getting damaged without any acknowledgement by the system or an admin, which makes it a significant problem for web hosting servers as failures are more likely to happen on larger hard disks where large volumes of information are stored. If a drive is a part of a RAID and the data on it is duplicated on other drives for redundancy, it's very likely that the bad file will be treated as a standard one and it'll be duplicated on all drives, making the damage permanent. Lots of the file systems which run on web servers these days often are not able to identify corrupted files right away or they need time-consuming system checks during which the server isn't operational.

No Data Corruption & Data Integrity in Cloud Website Hosting

The integrity of the data which you upload to your new cloud website hosting account will be ensured by the ZFS file system that we use on our cloud platform. The vast majority of web hosting service providers, like our company, use multiple HDDs to store content and considering that the drives work in a RAID, exactly the same information is synchronized between the drives all the time. If a file on a drive is damaged for reasons unknown, yet, it's very likely that it will be reproduced on the other drives since other file systems don't feature special checks for this. In contrast to them, ZFS applies a digital fingerprint, or a checksum, for every file. In the event that a file gets corrupted, its checksum won't match what ZFS has as a record for it, which means that the damaged copy shall be substituted with a good one from another hard disk. As this happens instantly, there's no risk for any of your files to ever be corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We have avoided any possibility 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 known as ZFS. Its main 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 save all content on numerous NVMe drives, ZFS checks if the fingerprint of a file on one drive matches the one on the other drives and the one it has saved. If there is a mismatch, the bad copy is replaced with a healthy one from one of the other drives and because it happens right away, there is no chance that a corrupted copy could remain on our web hosting servers or that it can be copied to the other hard disks in the RAID. None of the other file systems use this kind of checks and what's more, even during a file system check following an unexpected blackout, none of them will discover silently corrupted files. In comparison, ZFS will not crash after a blackout and the regular checksum monitoring makes a lenghty file system check obsolete.
