The process of files getting corrupted as a result of some hardware or software failure is called data corruption and this is among the main problems that Internet hosting companies face since the larger a hard disk drive is and the more information is stored on it, the more likely it is for data to be corrupted. There are several fail-safes, but often the information gets corrupted silently, so neither the file system, nor the admins detect a thing. As a result, a bad file will be treated as a standard one and if the hard disk is part of a RAID, the file will be duplicated on all other disk drives. In theory, this is for redundancy, but in practice the damage will get worse. The moment a given file gets damaged, it will be partly or completely 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 shall be impossible to unpack, and you risk losing your content. Although the most popular server file systems feature various checks, they frequently fail to detect some problem early enough or require an extensive time period to check all files and the server will not be operational in the meantime.

No Data Corruption & Data Integrity in Cloud Web Hosting

If you host your websites in a cloud web hosting account from our company, you won't have to worry about any of your data ever getting damaged. We can guarantee that because our cloud hosting platform works with the advanced ZFS file system. The aforementioned is the only file system which works with checksums, or unique digital fingerprints, for every single file. Any kind of information that you upload will be stored in a RAID i.e. simultaneously on many NVMe drives. A lot of file systems synchronize the files between the different drives with such a setup, but there is no real warranty that a file won't get corrupted. This can occur throughout the writing process on any drive and after that a damaged copy may be copied on the rest of the drives. What makes the difference on our platform is that ZFS compares the checksums of all files on all drives in real time and in case a corrupted file is identified, it is replaced with a good copy with the correct checksum from some other drive. That way, your data will remain intact no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You won't encounter any kind of silent data corruption issues in case you buy one of our semi-dedicated server packages since the ZFS file system that we take advantage of on our cloud hosting platform uses checksums to make sure that all files are intact all of the time. A checksum is a unique digital fingerprint that is assigned to each and every file kept on a server. Because we store all content on a number of drives at the same time, the same file uses the same checksum on all 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 probability of the bad copy to be synchronized on the rest of the drives. ZFS is the sole file system on the market which uses checksums, which makes it much more dependable than other file systems which are not able to identify silent data corruption and copy bad files across drives.
