Data corruption is the accidental modification of a file or the loss of information that usually occurs during reading or writing. The reason can be hardware or software failure, and due to this fact, a file may become partially or fully corrupted, so it will no longer function correctly since its bits shall be scrambled or missing. An image file, for example, will no longer show a real image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, and so on. If this kind of an issue appears and it is not recognized by the system or by an administrator, the data will be corrupted silently and in case this happens on a drive which is a part of a RAID array where the data is synchronized between various different drives, the corrupted file will be replicated on all other drives and the damage will be long term. Numerous widespread file systems either don't feature real-time checks or don't have high quality ones which will detect an issue before the damage is done, so silent data corruption is a very common matter on web hosting servers where large volumes of data are stored.

No Data Corruption & Data Integrity in Shared Web Hosting

The integrity of the data which you upload to your new shared web hosting account will be guaranteed by the ZFS file system which we take advantage of on our cloud platform. Most of the web hosting providers, including our company, use multiple hard disks to keep content and considering that the drives work in a RAID, identical info is synchronized between the drives all of the time. When a file on a drive becomes damaged for some reason, however, it is more than likely that it will be copied on the other drives since alternative file systems don't have special checks for that. In contrast to them, ZFS applies a digital fingerprint, or a checksum, for each and every file. If a file gets corrupted, its checksum will not match what ZFS has as a record for it, and the bad copy will be swapped with a good one from another drive. Since this happens immediately, there's no possibility for any of your files to ever get corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be resistant to silent data corruption because all of our storage servers employ the reliable ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, to guarantee the integrity of each file. When you upload content to your account, it will be stored on several redundant drives employed in a RAID i.e. the files will be the same on all 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 duplicates right away, and if it registers a mismatch, that will indicate that one of the copies is damaged, it'll swap that file with a good copy from one of the other disks. Even if there's an unexpected power loss, 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, lengthening the time needed for the server to return online. ZFS is the only file system that can truly protect your content from silent data corruption.
