No Data Corruption & Data Integrity
What exactly does the 'No Data Corruption & Data Integrity' slogan mean to each Internet hosting account user?
Data corruption is the unintentional transformation of a file or the loss of information that often occurs during reading or writing. The reason may be hardware or software fail, and as a result, a file can become partially or completely corrupted, so it will no longer work properly as its bits shall be scrambled or lacking. An image file, for instance, will no longer show an authentic image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, and so on. If this kind of a problem occurs and it isn't identified by the system or by an admin, the data will get corrupted silently and if this happens on a drive that is a part of a RAID array where the information is synced between various drives, the corrupted file will be copied on all the other drives and the damage will be long term. Many widespread file systems either don't offer real-time checks or don't have high quality ones which can detect an issue before the damage is done, so silent data corruption is a common problem on web hosting servers where huge volumes of info are stored.

No Data Corruption & Data Integrity in Shared Hosting
The integrity of the data that you upload to your new
shared hosting account will be guaranteed by the ZFS file system that we employ on our cloud platform. The majority of web hosting providers, including our company, use multiple hard disk drives to store content and considering that the drives work in a RAID, identical data is synchronized between the drives all the time. When a file on a drive gets corrupted for whatever reason, yet, it is more than likely that it will be reproduced on the other drives as other file systems don't include special checks for that. Unlike them, ZFS uses a digital fingerprint, or a checksum, for every file. In case a file gets damaged, its checksum won't match what ZFS has as a record for it, and the damaged copy shall be replaced with a good one from a different hard disk. Since this happens in real time, there is no risk for any of your files to ever be damaged.
