The process of files being damaged as a result of some hardware or software failure is called data corruption and this is one of the main problems which Internet hosting companies face because the larger a hard drive is and the more information is filed on it, the more likely it is for data to be corrupted. There're several fail-safes, but often the information is corrupted silently, so neither the file system, nor the administrators see a thing. As a result, a corrupted file will be treated as a regular one and if the hard disk drive is a part of a RAID, that particular file will be copied on all other drives. In principle, this is for redundancy, but in practice the damage will get even worse. When 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 blend 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 commonly used server file systems include various checks, they are likely to fail to find some problem early enough or require an extensive amount of time to be able to check all the files and the web hosting server will not be functional in the meantime.
No Data Corruption & Data Integrity in Cloud Website Hosting
In case you host your sites in a cloud website hosting account from our company, you don't need to worry about any of your data ever getting damaged. We can guarantee that as our cloud hosting platform employs the revolutionary ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for each file. All info that you upload will be saved in a RAID i.e. simultaneously on a large number of SSDs. All of the file systems synchronize the files between the different drives with such a setup, but there's no real guarantee that a file will not get corrupted. This may occur at the time of the writing process on each drive and afterwards a bad copy can be copied on all other drives. What makes the difference on our platform is the fact that ZFS examines the checksums of all files on all the drives instantly and when a corrupted file is found, it's replaced with a good copy with the correct checksum from some other drive. This way, your info will remain unharmed no matter what, even if a whole drive fails.
