The process of files being corrupted because of some hardware or software failure is referred to as data corruption and this is among the main problems which web hosting companies face as the larger a hard drive is and the more data is filed on it, the much more likely it is for data to be corrupted. There are different fail-safes, yet often the info gets corrupted silently, so neither the file system, nor the administrators notice a thing. Because of this, a bad file will be treated as a good one and if the hard drive is a part of a RAID, that file will be copied on all other disk drives. In theory, this is done for redundancy, but in practice the damage will be even worse. When a file gets damaged, it will be partially or completely unreadable, so a text file will not be readable, an image file will show a random blend of colors in case it opens at all and an archive will be impossible to unpack, and you risk losing your website content. Although the most widespread server file systems include various checks, they quite often fail to detect some problem early enough or require an extensive period of time to check all of the files and the hosting server will not be operational for the time being.
No Data Corruption & Data Integrity in Website Hosting
The integrity of the data that you upload to your new website hosting account shall be ensured by the ZFS file system that we make use of on our cloud platform. The vast majority of internet hosting service providers, including our company, use multiple HDDs to keep content and since the drives work in a RAID, identical information is synchronized between the drives all the time. If a file on a drive becomes damaged for some reason, yet, it's very likely that it will be copied on the other drives as alternative file systems don't feature special checks for that. In contrast to them, ZFS works with a digital fingerprint, or a checksum, for every file. In the event that a file gets corrupted, its checksum won't match what ZFS has as a record for it, which means that the damaged copy shall be swapped with a good one from another disk drive. Since this happens right away, there's no risk for any of your files to ever be damaged.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
Your semi-dedicated hosting account will be resistant to silent data corruption because all our storage servers make use of the reliable ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, in order to verify the integrity of each and every file. When you upload content to your account, it will be placed on a couple of redundant drives being employed in a RAID i.e. the files will be the same across all disk drives. All the copies of a specific file will have the same checksum on all hard disks and ZFS will compare the checksums of the copies quickly, so if it registers a mismatch, which will indicate that one of the copies is corrupted, it'll replace that file with a good copy from one of the other drives. Even if there is a sudden power loss, the data on the servers will not become corrupted and there will not be any need for a time-consuming system check that other file systems perform after some failure, prolonging the time needed for the server to go back online. ZFS is the sole file system that can truly protect your content from silent data corruption.
