The process of files being corrupted because of some hardware or software failure is called data corruption and this is among the main problems which Internet hosting companies face since the larger a hard disk is and the more information is placed on it, the much more likely it is for data to get corrupted. You'll find various fail-safes, but often the information is corrupted silently, so neither the file system, nor the administrators see anything. Thus, a damaged file will be handled as a regular one and if the hard disk is a part of a RAID, that file will be copied on all other disk drives. In principle, this is done for redundancy, but in reality the damage will get even worse. Once a given file gets corrupted, it will be partially or completely unreadable, therefore a text file will not be readable, an image file will display a random mix of colors if it opens at all and an archive shall be impossible to unpack, and you risk sacrificing your content. Although the most frequently used server file systems include various checks, they quite often fail to identify a problem early enough or require a vast time period to be able to check all of the files and the hosting server will not be operational in the meantime.
No Data Corruption & Data Integrity in Shared Hosting
In case you host your sites in a shared hosting account with our firm, you don't need to worry about any of your data ever getting corrupted. We can guarantee that since our cloud hosting platform uses the state-of-the-art ZFS file system. The aforementioned is the only file system that uses checksums, or unique digital fingerprints, for each and every file. Any information that you upload will be kept in a RAID i.e. simultaneously on numerous NVMe drives. All file systems synchronize the files between the separate drives with this type of a setup, but there's no real guarantee that a file won't get corrupted. This can happen throughout the writing process on each drive and afterwards a bad copy can be copied on all other drives. What makes the difference on our platform is the fact that ZFS examines the checksums of all files on all the drives right away and when a corrupted file is located, it is swapped with a good copy with the correct checksum from some other drive. By doing this, your information will stay intact no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Servers
We've avoided any risk of files getting corrupted silently since the servers where your semi-dedicated server account will be created employ a powerful file system named ZFS. Its main advantage over other file systems is that it uses a unique checksum for each file - a digital fingerprint which is checked in real time. As we store all content on a number of NVMe drives, ZFS checks if the fingerprint of a file on one drive matches the one on the remaining drives and the one it has stored. When there is a mismatch, the corrupted copy is replaced with a healthy one from one of the other drives and since it happens in real time, there is no chance that a corrupted copy can remain on our servers or that it can be copied to the other drives in the RAID. None of the other file systems include this kind of checks and what is more, even during a file system check after a sudden power loss, none of them can identify silently corrupted files. In comparison, ZFS won't crash after an electrical power failure and the continual checksum monitoring makes a lenghty file system check unnecessary.
