Data corruption is the accidental change of a file or the loss of information which usually occurs during reading or writing. The reason could be hardware or software failure, and as a result, a file could become partially or fully corrupted, so it'll no longer work as it should as its bits shall be scrambled or lost. An image file, for instance, will no longer display a true image, but a random combination of colors, an archive will be impossible to unpack because its content will be unreadable, etcetera. When this kind of an issue occurs and it's not noticed by the system or by an admin, 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 synchronized between various drives, the corrupted file will be replicated on all other drives and the harm will be long term. Many widespread 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 matter on internet hosting servers where huge volumes of info are stored.

No Data Corruption & Data Integrity in Shared Website Hosting

The integrity of the data which you upload to your new shared website hosting account shall be guaranteed by the ZFS file system which we take advantage of on our cloud platform. The vast majority of hosting suppliers, like our company, use multiple HDDs to store content and since the drives work in a RAID, identical info is synchronized between the drives at all times. In case a file on a drive gets damaged for some reason, however, it is 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 each file. In the event that a file gets corrupted, its checksum won't match what ZFS has as a record for it, so the bad copy shall be swapped with a good one from another hard disk drive. Due to the fact that this happens instantly, there is no possibility for any of your files to ever get corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

If you buy one of our semi-dedicated hosting solutions, you will not need to worry about silent file corruption because we use ZFS - a high level file system that monitors all files in real time. Whenever you upload a file to your web hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synchronized between several NVMe drives for redundancy, so if a drive fails, the other ones will take control. ZFS compares the checksum of all of the copies on the different drives and if it detects a corrupted copy, it replaces it with a healthy one from a different drive. This happens in real time, so there will be no risk for any part of your content at any moment. By comparison, alternative file systems carry out checks after a system failure, but since they don't use anything similar to the checksums that ZFS uses, they can't detect silently corrupted files, so a corrupted copy can be replicated on the remaining disks as well and you could lose crucial information. As this is not the case with ZFS, we can guarantee the integrity of each file you upload no matter what.
