Data corruption is the damage of information caused by various software or hardware fails. The moment a file gets damaged, it will no longer work as it should, so an application will not start or shall give errors, a text file shall be partially or entirely unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of info getting damaged without any identification by the system or an admin, which makes it a serious problem for hosting servers as fails are more likely to occur on larger hard disks where substantial volumes of information are located. In case a drive is a part of a RAID and the information on it is duplicated on other drives for redundancy, it's likely that the damaged file will be treated as an undamaged one and it'll be duplicated on all the drives, making the damage permanent. A huge number of the file systems that operate on web servers nowadays often cannot identify corrupted files in real time 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 ensured by the ZFS file system that we employ on our cloud platform. Most hosting providers, including our firm, use multiple HDDs to keep content and since the drives work in a RAID, the same data is synchronized between the drives all the time. When a file on a drive gets corrupted for whatever reason, yet, it's more than likely that it will be duplicated on the other drives since other file systems do not include special checks for that. In contrast to them, ZFS employs a digital fingerprint, or a checksum, for each file. In the event that a file gets corrupted, its checksum won't match what ZFS has as a record for it, therefore the damaged copy shall be swapped with a good one from another hard disk. Because this happens right away, there's no possibility for any of your files to ever get damaged.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We have avoided any chance of files getting corrupted silently as the servers where your semi-dedicated hosting account will be created use 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 that is checked in real time. As we save all content on multiple SSD drives, ZFS checks whether the fingerprint of a file on one drive corresponds to the one on the other drives and the one it has saved. If there is a mismatch, the bad copy is replaced with a good one from one of the other drives and considering that it happens in real time, there's no chance that a corrupted copy could remain on our servers or that it could be copied to the other drives in the RAID. None of the other file systems work with such checks and in addition, even during a file system check following an unexpected electrical power failure, none of them can discover silently corrupted files. In contrast, ZFS will not crash after a power loss and the regular checksum monitoring makes a time-consuming file system check obsolete.
