The process of files being damaged due to some hardware or software failure is known 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 information is kept on it, the more likely it is for data to be corrupted. You will find several fail-safes, but often the data gets corrupted silently, so neither the file system, nor the admins see a thing. As a result, a damaged file will be treated as a regular one and if the hard drive is a part of a RAID, that particular file will be copied on all other drives. Theoretically, this is done for redundancy, but in practice the damage will be worse. The moment a file gets corrupted, it will be partially or completely unreadable, therefore a text file will no longer be readable, an image file will display a random mix of colors in case it opens at all and an archive shall be impossible to unpack, and you risk losing your site content. Although the most commonly used server file systems include various checks, they often fail to identify some problem early enough or require a long time period in order to check all files and the server will not be functional in the meantime.

No Data Corruption & Data Integrity in Cloud Website Hosting

The integrity of the data which you upload to your new cloud website hosting account will be ensured by the ZFS file system that we employ on our cloud platform. Most of the web hosting service providers, like our company, use multiple hard disk drives to keep content and considering that the drives work in a RAID, identical data is synchronized between the drives all the time. If a file on a drive gets damaged for whatever reason, however, it's likely that it will be copied on the other drives as other file systems don't feature special checks for that. Unlike them, ZFS uses a digital fingerprint, or a checksum, for every file. In the event that a file gets damaged, its checksum won't match what ZFS has as a record for it, so the bad copy will be substituted with a good one from another hard disk. As this happens instantly, 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 since all our storage servers make use of the state-of-the-art ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, to guarantee the integrity of each file. When you upload content to your account, it'll be saved on a couple of redundant drives in a RAID i.e. the files shall be the same across all disks. All the copies of a given file will have the same checksum on all drives and ZFS will compare the checksums of the copies right away, so if it discovers a mismatch, that would indicate that one of the copies is damaged, it will swap that file with a good copy from one of the other drives. Even if there's an unexpected power loss, the data on the servers won't get corrupted and there will not be any need for a time-consuming system check which other file systems perform after some breakdown, prolonging the time needed for the server to get back online. ZFS is the file system which can really protect your content from silent data corruption.
