Data corruption is the accidental modification of a file or the losing of info that usually occurs during reading or writing. The reason could be hardware or software malfunction, and because of this, a file could become partially or fully corrupted, so it will no longer function correctly since its bits shall be scrambled or lacking. An image file, for instance, will no longer display 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. When such an issue occurs and it is not found by the system or by an administrator, the data will get corrupted silently and when this happens on a drive which is part of a RAID array where the info is synced between various drives, the corrupted file will be copied on all of the other drives and the harm will be long term. A number of commonly used file systems either do not offer real-time checks or do not have good ones which can detect a problem before the damage is done, so silent data corruption is a very common matter on internet hosting servers where substantial volumes of information are stored.

No Data Corruption & Data Integrity in Hosting

The integrity of the data which you upload to your new hosting account will be guaranteed by the ZFS file system which we take advantage of on our cloud platform. Most of the hosting service providers, like our company, use multiple hard disk drives to store content and considering that the drives work in a RAID, identical info is synchronized between the drives at all times. If a file on a drive becomes corrupted for reasons unknown, yet, it's likely that it will be copied on the other drives as alternative file systems don't include special checks for this. Unlike them, ZFS employs 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 damaged copy will be swapped with a good one from a different hard disk. As this happens instantly, there's no risk for any of your files to ever be damaged.

No Data Corruption & Data Integrity in Semi-dedicated Servers

If you purchase one of our semi-dedicated server solutions, you won't need to be concerned about silent file corruption since we use ZFS - an advanced file system that keeps track of all the files in real time. Every time you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synced between a number of NVMe drives for redundancy, so if one drive fails, the other ones will take control. ZFS compares the checksum of all the copies on the different drives and when it detects a corrupted copy, it replaces it with a healthy one from a different drive. This happens instantly, so there will be no risk for any part of your content at any moment. By comparison, all the other file systems execute checks only after a system breakdown, but since they don't use anything similar to the checksums that ZFS uses, they are unable to detect silently corrupted files, so a corrupted copy could be replicated on the remaining disks as well and you may lose important data. Because this is not the case with ZFS, we're able to guarantee the integrity of each file you upload no matter what.
