Data corruption is the unintentional modification of a file or the losing of information which often occurs during reading or writing. The reason can be hardware or software fail, and as a consequence, a file can become partially or fully corrupted, so it will no longer function as it should because its bits shall be scrambled or missing. An image file, for example, will no longer present a true image, but a random mix of colors, an archive will be impossible to unpack since its content will be unreadable, and so on. If such an issue occurs and it is not identified by the system or by an administrator, the data will be corrupted silently and in case this happens on a disk drive which is a part of a RAID array where the information is synced between various different drives, the corrupted file will be duplicated on all the other drives and the damage will become long term. A large number of widely used file systems either do not have real-time checks or don't have good ones which will detect an issue before the damage is done, so silent data corruption is a rather common matter on web hosting servers where large volumes of information 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 ensured by the ZFS file system which we use on our cloud platform. The majority of hosting providers, including our company, use multiple hard disk drives to keep content and because the drives work in a RAID, identical data is synchronized between the drives at all times. If a file on a drive is corrupted for reasons unknown, yet, it's likely that it will be duplicated on the other drives since alternative file systems do not offer special checks for this. In contrast to them, ZFS uses a digital fingerprint, or a checksum, for every file. If a file gets damaged, its checksum won't match what ZFS has as a record for it, which means that the bad copy shall be replaced with a good one from a different drive. As this happens in real time, there is no risk for any of your files to ever get corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be shielded from silent data corruption as all of our storage servers work with the reliable ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, so as to guarantee the integrity of each and every file. When you upload content to your account, it will be saved on a couple of redundant drives employed in a RAID i.e. the files will be the same across all disk drives. All the copies of a particular file will have the same checksum on all hard drives and ZFS will compare the checksums of the copies right away, so if it finds a mismatch, that will indicate that one of the copies is damaged, it'll replace that file with a healthy copy from one of the other disks. Even if there's a sudden power failure, the data on the servers will not get corrupted and there won't be any need for a time-consuming system check which other file systems perform following some malfunction, prolonging the time needed for the server to return online. ZFS is the sole file system that can truly protect your content from silent data corruption.
