The process of files getting corrupted because of some hardware or software failure is referred to as data corruption and this is one of the main problems that web hosting companies face because the larger a hard disk drive is and the more data is kept on it, the more likely it is for data to become corrupted. You can find a couple of fail-safes, still often the info becomes corrupted silently, so neither the file system, nor the admins detect a thing. Consequently, 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 duplicated on all other drives. In principle, this is for redundancy, but in reality the damage will get worse. When some file gets damaged, it will be partly or entirely unreadable, so a text file will no longer be readable, an image file will display a random mix of colors if it opens at all and an archive will be impossible to unpack, and you risk sacrificing your website content. Although the most widely used server file systems include various checks, they are likely to fail to discover a problem early enough or require a long time period to check all of the files and the web hosting server will not be functional for the time being.
No Data Corruption & Data Integrity in Cloud Hosting
The integrity of the data that you upload to your new cloud hosting account shall be guaranteed by the ZFS file system which we work with on our cloud platform. Most of the hosting service providers, like our firm, use multiple HDDs to store content and since the drives work in a RAID, the exact same info is synchronized between the drives all of the time. If a file on a drive becomes corrupted for some reason, yet, it is very likely that it will be duplicated on the other drives because alternative file systems do not have special checks for that. Unlike them, ZFS works with a digital fingerprint, or a checksum, for every file. In the event that a file gets damaged, its checksum will not match what ZFS has as a record for it, and the damaged copy will be swapped with a good one from a different disk drive. Because this happens instantly, there is no risk for any of your files to ever get damaged.
