The process of files being damaged caused by some hardware or software failure is referred to as data corruption and this is one of the main problems that Internet hosting companies face because the larger a hard disk drive is and the more information is filed on it, the more likely it is for data to get corrupted. You can find a couple of fail-safes, yet often the data gets damaged silently, so neither the particular file system, nor the admins see a thing. As a result, a bad file will be treated as a good one and if the HDD is a part of a RAID, that particular file will be duplicated on all other disk drives. In theory, this is done for redundancy, but in reality the damage will get even worse. The moment some file gets damaged, it will be partly or fully unreadable, so a text file will not be readable, an image file will present a random combination of colors in case it opens at all and an archive will be impossible to unpack, and you risk losing your site content. Although the most well-known server file systems have various checks, they are likely to fail to discover a problem early enough or require a long period of time to check all the files and the 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 ensured by the ZFS file system which we make use of on our cloud platform. Most hosting providers, like our company, use multiple hard drives to keep content and considering that the drives work in a RAID, exactly the same info is synchronized between the drives all of the time. When a file on a drive is corrupted for reasons unknown, however, it is likely that it will be duplicated on the other drives as other file systems do not feature special checks for that. In contrast to them, ZFS employs 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, therefore the damaged copy will be swapped with a good one from another hard disk. Due to the fact that this happens right away, there's no risk for any of your files to ever get damaged.
No Data Corruption & Data Integrity in Semi-dedicated Servers
Your semi-dedicated server
account will be shielded from silent data corruption because all of our storage servers use the state-of-the-art ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, to guarantee the integrity of each and every file. When you upload content to your account, it'll be saved on several redundant drives working in a RAID i.e. the files shall be the same across all disks. All of the copies of a given file will have the same checksum on all drives and ZFS will compare the checksums of the copies quickly, so if it finds a mismatch, that will indicate that one of the copies is damaged, it'll replace that file with a good copy from one of the other disks. Even if there's an unforeseen blackout, the data on the servers won't get corrupted and there won't be any need for a time-consuming system check which other file systems perform after some malfunction, extending the time needed for the server to get back online. ZFS is the sole file system that can really protect your content from silent data corruption.
