The process of files getting corrupted as a consequence of some hardware or software failure is known as data corruption and this is among the main problems that web hosting companies face since the larger a hard disk is and the more data is filed on it, the more likely it is for data to be corrupted. You can find several fail-safes, but often the data becomes damaged silently, so neither the file system, nor the administrators see anything. As a result, a damaged file will be treated as a regular one and if the hard disk drive is part of a RAID, that particular file will be copied on all other disk drives. In theory, this is done for redundancy, but in practice the damage will be worse. When some file gets damaged, it will be partly or completely unreadable, so a text file will no longer be readable, an image file will display a random mix of colors in case it opens at all and an archive shall be impossible to unpack, so you risk losing your site content. Although the most well-known server file systems include various checks, they quite often fail to identify some problem early enough or require a long time period to be able to check all files and the hosting server will not be operational in the meantime.

No Data Corruption & Data Integrity in Website Hosting

The integrity of the data that you upload to your new website hosting account shall be guaranteed by the ZFS file system that we take advantage of on our cloud platform. Most of the web hosting providers, like our company, use multiple HDDs to store content and considering that the drives work in a RAID, exactly the same info is synchronized between the drives at all times. When a file on a drive gets damaged for reasons unknown, yet, it is very likely that it will be duplicated on the other drives because other file systems do not include special checks for this. Unlike them, ZFS works with a digital fingerprint, or a checksum, for every file. In case a file gets corrupted, its checksum will not match what ZFS has as a record for it, so the damaged copy shall be substituted with a good one from a different hard drive. As this happens right away, there is no risk for any of your files to ever get corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We have avoided any risk of files getting corrupted silently due to the fact that the servers where your semi-dedicated hosting account will be created work with a powerful file system called ZFS. Its main advantage over other file systems is that it uses a unique checksum for every single file - a digital fingerprint that is checked in real time. Since we store all content on multiple SSD drives, ZFS checks whether the fingerprint of a file on one drive matches the one on the remaining drives and the one it has saved. In the event that there's a mismatch, the bad copy is replaced with a healthy one from one of the other drives and considering that this happens instantly, there's no chance that a damaged copy could remain on our website hosting servers or that it could be copied to the other drives in the RAID. None of the other file systems use this kind of checks and what is more, even during a file system check after a sudden power failure, none of them will discover silently corrupted files. In comparison, ZFS will not crash after a power failure and the continual checksum monitoring makes a time-consuming file system check unnecessary.
