Data corruption is the damage of data caused by various hardware or software fails. Once a file is corrupted, it will no longer function accurately, so an application will not start or will give errors, a text file can be partially or entirely unreadable, an archive file will be impossible to open and unpack, etc. Silent data corruption is the process of info getting harmed without any identification by the system or an administrator, which makes it a significant problem for hosting servers as problems are very likely to occur on larger hard disk drives where significant volumes of information are located. If a drive is a part of a RAID and the info on it is duplicated on other drives for redundancy, it is very likely that the bad file will be treated as an ordinary one and it'll be copied on all drives, making the harm permanent. A huge number of the file systems that run on web servers these days often cannot discover corrupted files immediately or they need time-consuming system checks through which the server isn't functioning.
No Data Corruption & Data Integrity in Website Hosting
The integrity of the data that you upload to your new website hosting
account will be guaranteed by the ZFS file system which we make use of on our cloud platform. The vast majority of internet hosting service providers, like our company, use multiple hard disk drives to keep content and because the drives work in a RAID, the exact same data is synchronized between the drives at all times. In case a file on a drive is corrupted for some reason, however, it's more than likely that it will be duplicated on the other drives as other file systems don't offer special checks for that. Unlike them, ZFS employs a digital fingerprint, or a checksum, for each and every file. If a file gets damaged, its checksum won't match what ZFS has as a record for it, therefore the damaged copy will be substituted with a good one from a different hard disk. Since this happens immediately, there is no possibility for any of your files to ever be damaged.
No Data Corruption & Data Integrity in Semi-dedicated Servers
We have avoided any probability of files getting damaged silently as the servers where your semi-dedicated server
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 keep all content on a number of SSD drives, ZFS checks if the fingerprint of a file on one drive corresponds to the one on the remaining drives and the one it has saved. If there is a mismatch, the damaged copy is replaced with a healthy one from one of the other drives and because it happens in real time, there is no chance that a corrupted copy can remain on our web hosting servers or that it can be copied to the other drives in the RAID. None of the other file systems work with this kind of checks and what's more, even during a file system check following an unexpected power loss, none of them will identify silently corrupted files. In contrast, ZFS will not crash after an electrical power failure and the regular checksum monitoring makes a time-consuming file system check obsolete.
