Data corruption is the damage of data because of various hardware or software failures. The moment a file gets damaged, it will no longer work correctly, so an application will not start or will give errors, a text file will be partially or entirely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of data getting damaged without any acknowledgement by the system or an admin, that makes it a serious problem for hosting servers as failures are much more likely to happen on bigger hard disks where considerable volumes of information are stored. In case a drive is a part of a RAID and the info on it is duplicated on other drives for redundancy, it is more than likely that the damaged file will be treated as an undamaged one and it'll be copied on all of the drives, making the damage permanent. A lot of the file systems which run on web servers today often cannot discover corrupted files immediately or they need time-consuming system checks during which the server isn't functioning.

No Data Corruption & Data Integrity in Shared Web Hosting

The integrity of the data that you upload to your new shared web hosting account shall be guaranteed by the ZFS file system which we take advantage of on our cloud platform. Most of the internet hosting providers, including our firm, use multiple hard disk drives to keep content and considering that the drives work in a RAID, the exact same data is synchronized between the drives at all times. When a file on a drive becomes corrupted for whatever reason, however, it's more than likely that it will be reproduced on the other drives as other file systems don't include special checks for that. Unlike them, ZFS employs a digital fingerprint, or a checksum, for each file. In case a file gets damaged, its checksum will not match what ZFS has as a record for it, so the bad copy will be replaced with a good one from another hard drive. Since this happens immediately, there's no possibility for any of your files to ever be corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We have avoided any chance of files getting damaged silently due to the fact that the servers where your semi-dedicated hosting account will be created use a powerful file system called ZFS. Its key advantage over various other file systems is that it uses a unique checksum for each and every file - a digital fingerprint that's checked in real time. As we store all content on numerous SSD drives, ZFS checks whether the fingerprint of a file on one drive matches the one on the remaining drives and the one it has stored. In the event that there is a mismatch, the bad copy is replaced with a good one from one of the other drives and since this happens in real time, there's no chance that a damaged copy can remain on our web servers or that it could be duplicated to the other hard drives in the RAID. None of the other file systems work with such checks and in addition, even during a file system check after a sudden power failure, none of them will find silently corrupted files. In comparison, ZFS will not crash after a power failure and the regular checksum monitoring makes a time-consuming file system check unneeded.
