The process of files getting damaged as a consequence of some hardware or software failure is known as data corruption and this is among the main problems that hosting companies face because the larger a hard drive is and the more info is filed on it, the more likely it is for data to become corrupted. You can find various fail-safes, but often the information gets corrupted silently, so neither the particular file system, nor the administrators see a thing. Consequently, a corrupted file will be treated as a standard one and if the HDD is part of a RAID, that file will be copied on all other disk drives. In principle, this is done for redundancy, but in reality the damage will be worse. Once some file gets damaged, it will be partially or completely unreadable, therefore a text file will not be readable, an image file will present a random combination of colors in case it opens at all and an archive shall be impossible to unpack, and you risk losing your site content. Although the most well-known server file systems have various checks, they quite often fail to identify some problem early enough or require a long period of time in order to check all the files and the web server will not be functional in the meantime.

No Data Corruption & Data Integrity in Cloud Hosting

If you host your sites in a cloud hosting account from our firm, you will not need to worry about your data ever getting damaged. We can guarantee that since our cloud hosting platform uses the advanced ZFS file system. The latter is the only file system that works with checksums, or unique digital fingerprints, for every single file. All info that you upload will be kept in a RAID i.e. simultaneously on numerous SSDs. 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 happen throughout the writing process on each drive and afterwards a corrupted copy can be copied on all other drives. What makes the difference on our platform is that ZFS analyzes the checksums of all files on all of the drives immediately and in case a corrupted file is identified, it's replaced with a good copy with the correct checksum from another drive. This way, your info will continue to be undamaged no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You will not have to deal with any kind of silent data corruption issues should you buy one of our semi-dedicated server solutions because the ZFS file system that we use on our cloud hosting platform uses checksums to make sure that all files are intact all the time. A checksum is a unique digital fingerprint which is given to each and every file stored on a server. As 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. In the event that 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 bad copy to be synchronized on the rest of the hard disks. ZFS is the sole file system you can get which uses checksums, which makes it much more dependable than other file systems which cannot detect silent data corruption and copy bad files across hard drives.
