The process of files getting corrupted due to some hardware or software failure is known as data corruption and this is one of the main problems that Internet hosting companies face because the larger a hard drive is and the more info is placed on it, the much more likely it is for data to get corrupted. You will find various fail-safes, but often the data is damaged silently, so neither the file system, nor the admins see anything. As a result, a bad file will be handled as a regular one and if the hard drive is part of a RAID, that file will be copied on all other disk drives. Theoretically, this is for redundancy, but in practice the damage will be worse. The moment some file gets damaged, it will be partially or fully unreadable, therefore a text file will no longer be readable, an image file will present a random blend of colors in case it opens at all and an archive will be impossible to unpack, and you risk sacrificing your website content. Although the most popular server file systems have various checks, they are likely to fail to find a problem early enough or require a vast time period to check all of the files and the web server will not be operational for the time being.
No Data Corruption & Data Integrity in Cloud Web Hosting
If you host your websites in a cloud web hosting account with our firm, you don't have to worry about your data ever getting corrupted. We can ensure that due to the fact that our cloud hosting platform uses the revolutionary ZFS file system. The latter is the only file system that works with checksums, or unique digital fingerprints, for each and every file. Any kind of info that you upload will be stored in a RAID i.e. simultaneously on many SSDs. All file systems synchronize the files between the separate drives using this type of a setup, but there is no real guarantee that a file won't be corrupted. This may occur throughout the writing process on each drive and afterwards a bad copy can be copied on the other drives. What is different on our platform is the fact that ZFS analyzes the checksums of all files on all the drives instantly and if a corrupted file is found, it's replaced with a good copy with the correct checksum from some other drive. In this way, your info will stay intact no matter what, even if an entire drive fails.
