The process of files getting damaged caused by some hardware or software failure is called data corruption and this is among the main problems which Internet hosting companies face because the larger a hard disk drive is and the more data is placed on it, the much more likely it is for data to get corrupted. You will find various fail-safes, yet often the information is damaged silently, so neither the file system, nor the administrators see a thing. As a result, a bad file will be treated as a standard one and if the hard disk drive is part of a RAID, the file will be copied on all other disk drives. In theory, this is done for redundancy, but in reality the damage will get worse. The moment some file gets damaged, it will be partly or completely unreadable, therefore a text file will no longer be readable, an image file will display a random combination of colors in case it opens at all and an archive shall be impossible to unpack, and you risk sacrificing your site content. Although the most widely used server file systems have various checks, they are likely to fail to detect some problem early enough or require an extensive amount of time to be able to check all of the files and the web server will not be functional for the time being.

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 employ on our cloud platform. Most of the hosting service providers, like our firm, use multiple hard disks to keep content and considering that the drives work in a RAID, exactly the same information is synchronized between the drives all the time. In case a file on a drive becomes damaged for reasons unknown, however, it's more than likely that it will be reproduced on the other drives as other file systems do not feature special checks for that. Unlike them, ZFS uses a digital fingerprint, or a checksum, for each and every file. In case a file gets damaged, its checksum will not match what ZFS has as a record for it, which means that the damaged copy will be substituted with a good one from another hard disk. As this happens right away, there is no possibility for any of your files to ever be damaged.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We've avoided any probability of files getting damaged silently since the servers where your semi-dedicated server account will be created take advantage of a powerful file system known as ZFS. Its advantage over other file systems is that it uses a unique checksum for each and every file - a digital fingerprint which is checked in real time. Since we keep all content on numerous 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. If there's a mismatch, the damaged copy is replaced with a healthy one from one of the other drives and since it happens right away, there's no chance that a corrupted copy could remain on our web servers or that it could be copied to the other drives in the RAID. None of the other file systems include this type of checks and in addition, even during a file system check after a sudden electrical power failure, none of them will detect silently corrupted files. In contrast, ZFS will not crash after a power loss and the constant checksum monitoring makes a lenghty file system check obsolete.
