The process of files being corrupted as a result of some hardware or software failure is known as data corruption and this is among the main problems that hosting companies face since the larger a hard disk is and the more info is filed on it, the much more likely it is for data to get corrupted. You'll find several fail-safes, still often the info is corrupted silently, so neither the file system, nor the administrators detect anything. As a result, a corrupted file will be handled 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 worse. Once a file gets damaged, it will be partly or fully unreadable, therefore a text file will no longer be readable, an image file will show a random mix of colors in case it opens at all and an archive will be impossible to unpack, so you risk sacrificing your website content. Although the most commonly used server file systems have various checks, they are likely to fail to discover some problem early enough or require a long amount of time to be able to check all of the files and the hosting server will not be operational in the meantime.
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 take advantage of on our cloud platform. The majority of internet hosting providers, like our firm, use multiple hard disk drives to keep content and since the drives work in a RAID, the same data is synchronized between the drives at all times. In case a file on a drive is corrupted for some reason, however, it is more than likely that it will be duplicated on the other drives because alternative file systems do not offer special checks for that. Unlike them, ZFS applies a digital fingerprint, or a checksum, for each and every file. If 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 another disk drive. Because this happens in real time, there is no possibility for any of your files to ever be damaged.
