Data corruption is the damage of data because of various software or hardware failures. The moment a file is damaged, it will no longer function properly, so an application will not start or shall give errors, a text file shall 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 harmed without any acknowledgement by the system or an admin, which makes it a significant problem for website hosting servers as fails are much more likely to happen on bigger hard disks where considerable volumes of info are stored. If a drive is part of a RAID and the info on it is replicated on other drives for redundancy, it is more than likely that the bad file will be treated as an undamaged one and it will be duplicated on all the drives, making the damage permanent. A lot of the file systems which operate on web servers nowadays often are unable to locate corrupted files instantly or they need time-consuming system checks through which the server is not working.
No Data Corruption & Data Integrity in Shared Web Hosting
We guarantee the integrity of the info uploaded in any shared web hosting account that is generated on our cloud platform due to the fact that we work with the advanced ZFS file system. The aforementioned is the only one that was designed to avert silent data corruption via a unique checksum for every single file. We shall store your information on a large number of SSD drives that operate in a RAID, so exactly the same files will exist on several places at the same time. ZFS checks the digital fingerprint of all the files on all the drives in real time and in the event that the checksum of any file differs from what it needs to be, the file system replaces that file with a healthy version from another drive in the RAID. There's no other file system that uses checksums, so it is possible for data to be silently damaged and the bad file to be reproduced on all drives over time, but since this can never happen on a server running ZFS, you will not have to concern yourself with the integrity of your info.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
We have avoided any risk of files getting corrupted silently because the servers where your semi-dedicated hosting account will be created take advantage of a powerful file system called ZFS. Its key advantage over alternative file systems is that it uses a unique checksum for every single file - a digital fingerprint which is checked in real time. Since we keep all content on multiple SSD drives, ZFS checks if the fingerprint of a file on one drive matches the one on the other drives and the one it has stored. In the event that there's a mismatch, the corrupted copy is replaced with a healthy one from one of the other drives and considering that this happens right away, there is no chance that a damaged copy can remain on our servers or that it could be duplicated to the other drives in the RAID. None of the other file systems include this kind of checks and in addition, even during a file system check after an unexpected electrical power failure, none of them will find silently corrupted files. In contrast, ZFS will not crash after a blackout and the continual checksum monitoring makes a lenghty file system check unneeded.
