The process of files being corrupted resulting from some hardware or software failure is called data corruption and this is among the main problems which hosting companies face since the larger a hard drive is and the more data is kept on it, the much more likely it is for data to get corrupted. You can find different fail-safes, but often the info is damaged silently, so neither the particular file system, nor the administrators notice a thing. Thus, a bad file will be treated as a regular one and if the hard disk is part of a RAID, the file will be duplicated on all other disk drives. In principle, this is for redundancy, but in practice the damage will be even worse. The moment a file gets damaged, it will be partially or completely unreadable, so a text file will no longer be readable, an image file will display a random mix of colors if it opens at all and an archive will be impossible to unpack, so you risk sacrificing your site content. Although the most frequently used server file systems have various checks, they often fail to identify a problem early enough or require an extensive amount of time in order to check all the files and the web hosting server will not be operational in the meantime.
No Data Corruption & Data Integrity in Cloud Website Hosting
If you host your websites in a cloud website hosting account with our company, you don't need to worry about your data ever getting damaged. We can ensure that as our cloud hosting platform uses the cutting-edge ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for every single file. All information that you upload will be stored in a RAID i.e. simultaneously on multiple NVMes. All file systems synchronize the files between the different drives with such a setup, but there is no real guarantee that a file will not get corrupted. This could happen throughout the writing process on any drive and then a damaged copy can be copied on the other drives. What makes the difference on our platform is that ZFS examines the checksums of all files on all the drives immediately and if a corrupted file is identified, it's swapped with a good copy with the correct checksum from another drive. By doing this, your data will remain undamaged no matter what, even if a whole drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
We have avoided any chance of files getting corrupted silently due to the fact that the servers where your semi-dedicated hosting account will be created take advantage of a powerful file system called ZFS. Its basic advantage over various other file systems is that it uses a unique checksum for every single file - a digital fingerprint that is checked in real time. As we store all content on multiple NVMe drives, ZFS checks if the fingerprint of a file on one drive matches the one on the rest of the drives and the one it has saved. If 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 can remain on our web hosting servers or that it can be duplicated to the other hard drives in the RAID. None of the other file systems use such checks and what is more, even during a file system check right after a sudden electrical power failure, none of them will find silently corrupted files. In contrast, ZFS does not crash after a power failure and the regular checksum monitoring makes a time-consuming file system check obsolete.
