The process of files getting corrupted as a result of some hardware or software failure is known as data corruption and this is one of the main problems that Internet hosting companies face as the larger a hard drive is and the more data is stored on it, the much more likely it is for data to be corrupted. You will find several fail-safes, but often the data becomes damaged silently, so neither the particular file system, nor the administrators see a thing. Consequently, a damaged file will be handled as a standard one and if the HDD is a part of a RAID, that file will be duplicated on all other disk drives. Theoretically, this is done for redundancy, but in reality the damage will be worse. Once some file gets corrupted, it will be partly or fully unreadable, which means that 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 shall be impossible to unpack, so you risk losing your content. Although the most well-known server file systems include various checks, they quite often fail to find a problem early enough or require an extensive period of time to be able to check all 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 from our company, you don't need to worry about any of your data ever getting damaged. We can ensure that due to the fact that our cloud hosting platform works with the reliable ZFS file system. The latter is the only file system that uses checksums, or unique digital fingerprints, for each file. All the information that you upload will be stored in a RAID i.e. simultaneously on a number of NVMe drives. All of the file systems synchronize the files between the separate drives with this type of a setup, but there's no real guarantee that a file will not be corrupted. This could occur throughout the writing process on any drive and after that a corrupted copy can be copied on all other drives. What makes the difference on our platform is the fact that ZFS analyzes the checksums of all files on all the drives in real time and in case a corrupted file is discovered, it is swapped with a good copy with the correct checksum from another drive. In this way, your information will stay unharmed no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You won't need to deal with any kind of silent data corruption issues in case you obtain one of our semi-dedicated server solutions because the ZFS file system that we employ on our cloud hosting platform uses checksums in order to make sure that all of your files are undamaged at all times. A checksum is a unique digital fingerprint that is allotted to each and every file kept on a server. Because we store all content on a number of drives simultaneously, the same file has the same checksum on all of the drives and what ZFS does is that it compares the checksums between the different drives in real time. If it detects that a file is corrupted and its checksum is different from what it should be, it replaces that file with a healthy copy without delay, avoiding any chance of the damaged copy to be synchronized on the other hard drives. ZFS is the sole file system you can find that uses checksums, which makes it much more reliable than other file systems that are unable to detect silent data corruption and copy bad files across drives.
