The process of files being damaged owing to some hardware or software failure is known as data corruption and this is among the main problems that hosting companies face as the larger a hard disk drive is and the more information is placed on it, the more likely it is for data to be corrupted. There are various fail-safes, still often the information becomes damaged silently, so neither the particular file system, nor the admins notice a thing. Thus, a damaged file will be treated as a good one and if the hard disk is a part of a RAID, that particular file will be copied on all other disk drives. In principle, this is done for redundancy, but in reality the damage will be even worse. Once a given file gets corrupted, it will be partially or fully unreadable, which means that a text file will not be readable, an image file will present a random blend of colors if it opens at all and an archive shall be impossible to unpack, and you risk losing your content. Although the most well-known server file systems feature various checks, they frequently fail to identify a problem early enough or require an extensive period of time to check all of the files and the server will not be operational for the time being.
No Data Corruption & Data Integrity in Web Hosting
In case you host your Internet sites in a web hosting account from our firm, you won't need to worry about any of your data ever getting damaged. We can ensure that as our cloud hosting platform employs the leading-edge ZFS file system. The aforementioned is the only file system that works with checksums, or unique digital fingerprints, for each file. All data that you upload will be kept in a RAID i.e. simultaneously on many SSD drives. All of the file systems synchronize the files between the separate drives using this kind of a setup, but there is no real guarantee that a file won't get corrupted. This may happen during the writing process on each drive and then a corrupted copy can be copied on all other drives. What is different on our platform is that ZFS compares the checksums of all files on all of the drives right away and when a corrupted file is discovered, it is replaced with a good copy with the correct checksum from another drive. In this way, your information will continue to be intact no matter what, even if a whole drive fails.
