Data corruption is the unintentional transformation of a file or the losing of information that usually occurs during reading or writing. The reason could be hardware or software malfunction, and as a consequence, a file could become partially or fully corrupted, so it'll no longer function as it should as its bits shall be scrambled or lost. An image file, for instance, will no longer display an authentic image, but a random combination of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, and so on. In the event that this kind of an issue appears and it is not found by the system or by an admin, the data will get corrupted silently and when this happens on a drive that is part of a RAID array where the info is synchronized between various drives, the corrupted file will be copied on all other drives and the harm will become permanent. Many widely used file systems either don't feature real-time checks or do not have good ones that can detect a problem before the damage is done, so silent data corruption is a very common problem on web hosting servers where large amounts of data are kept.

No Data Corruption & Data Integrity in Shared Hosting

The integrity of the data which you upload to your new shared hosting account shall be guaranteed by the ZFS file system that we take advantage of on our cloud platform. The vast majority of web hosting service providers, including our firm, use multiple hard disk drives to keep content and considering that the drives work in a RAID, the same info is synchronized between the drives all of the time. When a file on a drive becomes damaged for reasons unknown, however, it is more than likely that it will be copied on the other drives because other file systems don't feature special checks for this. In contrast to them, ZFS employs a digital fingerprint, or a checksum, for every single file. If a file gets corrupted, its checksum won't match what ZFS has as a record for it, and the bad copy shall be swapped with a good one from another hard disk drive. As this happens immediately, there is no possibility for any of your files to ever be corrupted.

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 use the reliable ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, in order to verify the integrity of each 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 on all drives. All the copies of a particular file will have the same checksum on all hard disks and ZFS will compare the checksums of the copies right away, so if it finds a mismatch, that would indicate that one of the copies is damaged, it'll replace that file with a healthy copy from one of the other drives. Even if there is an unexpected power loss, the data on the servers won't become corrupted and there will not be any need for a time-consuming system check which other file systems perform following some malfunction, extending the time needed for the server to get back online. ZFS is the file system that can truly protect your content from silent data corruption.
