The process of files being damaged as a consequence of some hardware or software failure is referred to as data corruption and this is among the main problems that web hosting companies face as the larger a hard disk is and the more information is filed on it, the more likely it is for data to get corrupted. You'll find several fail-safes, still often the information becomes damaged silently, so neither the particular file system, nor the admins notice anything. Thus, a bad file will be handled as a standard one and if the hard disk is part of a RAID, that particular file will be duplicated on all other drives. In theory, this is done for redundancy, but in reality the damage will be worse. When some file gets corrupted, it will be partly or entirely unreadable, so a text file will not be readable, an image file will display a random blend 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 widely used server file systems feature various checks, they often fail to find some problem early enough or require a vast time period to be able to check all of the files and the server will not be operational 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 ensured by the ZFS file system which we use on our cloud platform. The majority of hosting providers, including our company, use multiple HDDs to keep content and considering that the drives work in a RAID, the exact same data is synchronized between the drives all the time. If a file on a drive becomes damaged for reasons unknown, yet, it's likely that it will be reproduced on the other drives because other file systems don't have special checks for this. Unlike them, ZFS uses a digital fingerprint, or a checksum, for every file. In case a file gets damaged, its checksum will not match what ZFS has as a record for it, which means that the bad copy shall be substituted with a good one from another hard disk drive. As this happens instantly, there is no risk for any of your files to ever be corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be resistant to silent data corruption as all of our storage servers employ the innovative ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, so as to verify the integrity of each and every file. When you upload content to your account, it will be stored on several redundant drives in a RAID i.e. the files will be the same across all disk drives. All the copies of a specific file will feature the same checksum on all drives and ZFS will compare the checksums of the copies right away, so if it discovers a mismatch, which would indicate that one of the copies is corrupted, it'll swap that file with a healthy copy from one of the other disks. Even if there is an unexpected power failure, the data on the servers will not be corrupted and there will not be any need for a time-consuming system check that other file systems perform following some breakdown, extending the time needed for the server to go back online. ZFS is the file system that can truly protect your content from silent data corruption.
