The process of files getting damaged caused by some hardware or software failure is known as data corruption and this is one of the main problems which Internet hosting companies face as the larger a hard drive is and the more info is placed on it, the much more likely it is for data to be corrupted. There are several fail-safes, still often the info is damaged silently, so neither the file system, nor the administrators detect a thing. Thus, a corrupted file will be handled as a standard one and if the hard drive is a part of a RAID, that particular file will be copied on all other drives. Theoretically, this is done for redundancy, but in practice the damage will get worse. The moment a given file gets damaged, it will be partly or entirely unreadable, therefore a text file will no longer be readable, an image file will display a random combination of colors if it opens at all and an archive will be impossible to unpack, and you risk losing your content. Although the most frequently used server file systems have various checks, they are likely to fail to detect a problem early enough or require a long period of time in order to check all files and the server will not be operational in the meantime.
No Data Corruption & Data Integrity in Web Hosting
If you host your websites in a web hosting account from our firm, you do not need to worry about your data ever getting corrupted. We can guarantee that since our cloud hosting platform employs the cutting-edge ZFS file system. The aforementioned is the only file system which works with checksums, or unique digital fingerprints, for each file. All the information that you upload will be kept in a RAID i.e. simultaneously on multiple NVMes. Many file systems synchronize the files between the different drives with this kind of a setup, but there's no real warranty that a file will not be corrupted. This may occur at the time of the writing process on any drive and then a damaged copy may be copied on all other drives. What makes the difference on our platform is that ZFS analyzes the checksums of all files on all drives live and when a corrupted file is found, it is substituted with a good copy with the correct checksum from some other drive. That way, your info will stay intact no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Servers
You won't experience any kind of silent data corruption issues whatsoever in case you obtain one of our semi-dedicated server packages due to the fact that the ZFS file system that we work with on our cloud hosting platform uses checksums in order to make sure that all of the files are undamaged at all times. A checksum is a unique digital fingerprint which is assigned to each and every file saved on a server. Because we store all content on multiple drives simultaneously, the same file uses 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 possibility of the corrupted copy to be synchronized on the other hard drives. ZFS is the sole file system you will find which uses checksums, which makes it much more reliable than other file systems which are unable to identify silent data corruption and duplicate bad files across drives.
