The process of files being damaged resulting from some hardware or software failure is called data corruption and this is among the main problems which web hosting companies face as the larger a hard disk is and the more information is filed on it, the much more likely it is for data to be corrupted. You can find a couple of fail-safes, still often the data is damaged silently, so neither the file system, nor the admins detect a thing. Thus, a corrupted file will be handled as a regular one and if the hard drive is part of a RAID, that file will be copied on all other disk drives. In theory, this is for redundancy, but in reality the damage will be even worse. When some file gets damaged, it will be partly or fully unreadable, therefore a text file will no longer be readable, an image file will show a random mix 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 popular server file systems have various checks, they are likely to fail to detect some problem early enough or require an extensive time period to check all the files and the web hosting server will not be functional for the time being.
No Data Corruption & Data Integrity in Cloud Website Hosting
In case you host your Internet sites in a cloud website hosting account from our firm, you will not need to worry about your data ever getting corrupted. We can guarantee that since our cloud hosting platform works with the state-of-the-art ZFS file system. The aforementioned is the only file system that works with checksums, or unique digital fingerprints, for every single file. Any info that you upload will be stored in a RAID i.e. simultaneously on many NVMe drives. All of the file systems synchronize the files between the separate drives with this kind of a setup, but there is no real warranty that a file won't get corrupted. This could happen during the writing process on any drive and then a damaged copy may be copied on all other drives. What is different on our platform is the fact that ZFS compares the checksums of all files on all the drives live and in case a corrupted file is found, it's substituted with a good copy with the correct checksum from some other drive. By doing this, your data will remain unharmed no matter what, even if a whole drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Servers
We have avoided any risk of files getting corrupted silently because the servers where your semi-dedicated server account will be created use a powerful file system named ZFS. Its main advantage over alternative file systems is that it uses a unique checksum for each file - a digital fingerprint which is checked in real time. Since we keep all content on multiple NVMe drives, ZFS checks whether 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 is a mismatch, the bad copy is replaced with a healthy one from one of the other drives and considering that this happens right away, there is no chance that a damaged copy can remain on our hosting servers or that it can be copied to the other hard drives in the RAID. None of the other file systems employ this kind of checks and furthermore, even during a file system check right after an unexpected blackout, none of them will find silently corrupted files. In contrast, ZFS does not crash after a blackout and the regular checksum monitoring makes a time-consuming file system check obsolete.
