Data corruption is the unintentional change of a file or the loss of info which usually occurs during reading or writing. The reason may be hardware or software failure, and because of this, a file could become partially or completely corrupted, so it will no longer work as it should because its bits shall be scrambled or missing. An image file, for instance, 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, etcetera. If this kind of a problem occurs and it's not found by the system or by an administrator, the data will get corrupted silently and if this happens on a drive that is a part of a RAID array where the info is synced between various different drives, the corrupted file will be reproduced on all the other drives and the harm will be permanent. Numerous widespread file systems either do not feature real-time checks or don't have good ones that will detect a problem before the damage is done, so silent data corruption is a common issue on internet hosting servers where substantial amounts of information are kept.

No Data Corruption & Data Integrity in Cloud Web Hosting

The integrity of the data that you upload to your new cloud web hosting account shall be ensured by the ZFS file system that we employ on our cloud platform. Most of the web hosting providers, including our company, use multiple hard drives to store content and since the drives work in a RAID, identical information is synchronized between the drives all of the time. In case a file on a drive gets damaged for reasons unknown, yet, it's more than likely that it will be duplicated on the other drives because alternative file systems don't feature special checks for this. Unlike them, ZFS works with a digital fingerprint, or a checksum, for each and every file. In the event that a file gets damaged, its checksum won't match what ZFS has as a record for it, and the bad copy will be substituted with a good one from a different hard drive. Since this happens in real time, there's no risk for any of your files to ever get damaged.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

In case you buy one of our semi-dedicated hosting packages, you won't have to worry about silent file corruption as we use ZFS - an advanced file system which monitors all the files in real time. Whenever you upload a file to your website hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synced between multiple SSD drives for redundancy, so if a drive fails, the other ones will take control. ZFS compares the checksum of all copies on the different drives and in case it detects a damaged copy, it replaces it with a healthy one from a different drive. This happens in real time, so there will be no danger for any part of your content at any time. By comparison, all the other file systems perform checks only after a system breakdown, but since they don't use anything similar to the checksums which ZFS uses, they cannot detect silently corrupted files, so a corrupted copy could be replicated on the other disks as well and you could lose precious data. As this is not the case with ZFS, we warrant the integrity of each and every file you upload no matter what.
