The process of files getting corrupted because of some hardware or software failure is referred to as data corruption and this is one of the main problems that Internet hosting companies face because the larger a hard drive 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, yet often the data is corrupted silently, so neither the file system, nor the administrators notice anything. Consequently, a corrupted file will be handled as a good one and if the HDD is part of a RAID, the file will be copied on all other disk drives. In theory, this is for redundancy, but in practice the damage will get worse. When a given file gets corrupted, it will be partially or completely unreadable, so a text file will not be readable, an image file will display a random combination of colors in case it opens at all and an archive will be impossible to unpack, so you risk losing your content. Although the most widespread server file systems include various checks, they are likely to fail to discover some problem early enough or require a long time period in order to check all files and the web hosting server will not be operational in the meantime.

No Data Corruption & Data Integrity in Website Hosting

The integrity of the data which you upload to your new website hosting account shall be ensured by the ZFS file system that we use on our cloud platform. Most hosting service providers, like our firm, use multiple hard drives to keep content and since the drives work in a RAID, the exact same info is synchronized between the drives all of the time. When a file on a drive gets corrupted for some reason, yet, it is more than likely that it will be duplicated on the other drives as other file systems do not feature special checks for this. Unlike them, ZFS employs a digital fingerprint, or a checksum, for each file. In the event that a file gets damaged, its checksum won't match what ZFS has as a record for it, which means that the damaged copy will be replaced with a good one from another hard disk drive. Due to the fact that this happens in real time, there is no possibility for any of your files to ever be corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We have avoided any probability of files getting damaged silently because the servers where your semi-dedicated hosting account will be created employ a powerful file system named ZFS. Its key advantage over other file systems is that it uses a unique checksum for each file - a digital fingerprint that is checked in real time. Since we store all content on numerous SSD drives, ZFS checks if the fingerprint of a file on one drive corresponds to the one on the rest of the 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 this happens in real time, there's no chance that a damaged 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 employ this type of checks and what is more, even during a file system check after a sudden power failure, none of them can detect silently corrupted files. In comparison, ZFS won't crash after an electrical power failure and the constant checksum monitoring makes a time-consuming file system check unneeded.
