The process of files getting damaged as a result of some hardware or software failure is referred to as data corruption and this is one of the main problems which Internet hosting companies face because the larger a hard drive is and the more info is kept on it, the more likely it is for data to be corrupted. There are several fail-safes, still often the information gets corrupted silently, so neither the file system, nor the administrators detect anything. As a result, a bad file will be handled as a good one and if the hard disk drive is part of a RAID, that particular file will be copied on all other drives. Theoretically, this is for redundancy, but in practice the damage will be even worse. The moment a file gets damaged, it will be partly or fully unreadable, so a text file will no longer be readable, an image file will present a random mix of colors if it opens at all and an archive shall be impossible to unpack, and you risk losing your site content. Although the most widespread server file systems have various checks, they frequently fail to find a problem early enough or require a vast period of time to check all the files and the hosting server will not be functional for the time being.

No Data Corruption & Data Integrity in Shared Website Hosting

In case you host your websites in a shared website hosting account from our company, you will not need to worry about your data ever getting corrupted. We can guarantee that because our cloud hosting platform works with the advanced ZFS file system. The latter is the only file system that uses checksums, or unique digital fingerprints, for each file. All the data that you upload will be saved in a RAID i.e. simultaneously on many NVMes. Many file systems synchronize the files between the separate drives with this type of a setup, but there's no real warranty that a file won't be corrupted. This may happen during the writing process on any drive and then a damaged copy may be copied on the rest of the drives. What is different on our platform is that ZFS compares the checksums of all files on all the drives instantly and when a corrupted file is discovered, it is substituted with a good copy with the correct checksum from some other drive. By doing this, your data will stay undamaged no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We have avoided any risk of files getting damaged silently because the servers where your semi-dedicated server account will be created employ a powerful file system named ZFS. Its key advantage over various other file systems is that it uses a unique checksum for each and every file - a digital fingerprint that is checked in real time. Since we save all content on multiple NVMe drives, ZFS checks if the fingerprint of a file on one drive matches the one on the other drives and the one it has saved. When there's a mismatch, the corrupted copy is replaced with a good one from one of the other drives and considering that this happens right away, there is no chance that a corrupted copy can remain on our web servers or that it could be copied to the other hard drives in the RAID. None of the other file systems include such checks and furthermore, even during a file system check following a sudden power failure, none of them will detect silently corrupted files. In contrast, ZFS does not crash after an electrical power failure and the continual checksum monitoring makes a time-consuming file system check unnecessary.
