Data corruption is the unintended change of a file or the loss of information which usually occurs during reading or writing. The reason could be hardware or software malfunction, and as a consequence, a file may become partially or entirely corrupted, so it'll no longer work properly because its bits shall be scrambled or lacking. An image file, for example, will no longer present an actual image, but a random mix of colors, an archive will be impossible to unpack since its content will be unreadable, etc. In case this kind of a problem appears and it is not noticed by the system or by an administrator, the data will be corrupted silently and if this happens on a drive that's part of a RAID array where the information is synced between various different drives, the corrupted file shall be reproduced on all the other drives and the damage will be long term. A large number of popular file systems either do not feature real-time checks or do not have high quality ones which will detect a problem before the damage is done, so silent data corruption is a common problem on internet hosting servers where large amounts of information are stored.

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 which we work with on our cloud platform. The vast majority of hosting suppliers, like our company, use multiple hard disks to keep content and because the drives work in a RAID, the same information is synchronized between the drives all the time. If a file on a drive is corrupted for whatever reason, however, it's likely that it will be duplicated on the other drives as alternative file systems do not feature special checks for this. In contrast to them, ZFS works with a digital fingerprint, or a checksum, for every file. In case a file gets corrupted, its checksum won't match what ZFS has as a record for it, which means that the bad copy will be substituted with a good one from a different drive. Since this happens in real time, there's 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 shielded from silent data corruption since all our storage servers work with the effective ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, in order to guarantee the integrity of each and every file. When you upload content to your account, it'll be kept on several redundant drives working in a RAID i.e. the files will be the same on all drives. All copies of a given file will have the same checksum on all hard disks and ZFS will compare the checksums of the duplicates quickly, and if it discovers 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 is a sudden power loss, the data on the servers won't be 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 get back online. ZFS is the sole file system which can truly protect your content from silent data corruption.
