No Data Corruption & Data Integrity
What exactly does the 'No Data Corruption & Data Integrity' slogan mean to every web hosting account owner?
Data corruption is the damage of information caused by various software or hardware fails. When a file gets corrupted, it will no longer function properly, 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 then unpack, etc. Silent data corruption is the process of info getting damaged without any identification by the system or an admin, that makes it a serious problem for web hosting servers as problems are more likely to occur on larger hard disks where significant volumes of info are located. In case a drive is a part of a RAID and the information on it is replicated on other drives for redundancy, it's more than likely that the bad file will be treated as a healthy one and will be copied on all the drives, making the harm permanent. Lots of the file systems which run on web servers nowadays often cannot locate corrupted files instantly or they need time-consuming system checks through which the server isn't operational.
No Data Corruption & Data Integrity in Web Hosting
We guarantee the integrity of the data uploaded in each web hosting
account that is made on our cloud platform due to the fact that we employ the advanced ZFS file system. The aforementioned is the only one which was designed to avert silent data corruption thanks to a unique checksum for each file. We'll store your data on a number of SSD drives that operate in a RAID, so identical files will exist 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 is different from what it has to be, the file system replaces that file with a healthy copy from another drive from the RAID. There's no other file system which uses checksums, so it is easy for data to get silently damaged and the bad file to be reproduced on all drives over time, but since that can never happen on a server running ZFS, you don't have to concern yourself with the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Servers
We have avoided any risk of files getting damaged silently due to the fact that the servers where your semi-dedicated server
account will be created employ a powerful file system named ZFS. Its main advantage over alternative 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 corresponds to the one on the rest of the drives and the one it has stored. In the event that there is a mismatch, the damaged copy is replaced with a healthy one from one of the other drives and since this happens in real time, there's no chance that a corrupted copy can remain on our web hosting servers or that it can be duplicated to the other hard disks in the RAID. None of the other file systems include this kind of checks and furthermore, even during a file system check after an unexpected power loss, none of them will discover silently corrupted files. In contrast, ZFS will not crash after an electrical power failure and the regular checksum monitoring makes a lenghty file system check obsolete.
