Data corruption is the accidental change of a file or the loss of info which usually occurs during reading or writing. The reason may be hardware or software fail, and consequently, a file can become partially or completely corrupted, so it will no longer function as it should as its bits shall be scrambled or missing. An image file, for instance, will no longer present a real image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, etcetera. If this kind of an issue occurs and it is not identified by the system or by an admin, the data will get corrupted silently and if this happens on a disk drive that is a part of a RAID array where the info is synced between various drives, the corrupted file will be duplicated on all other drives and the damage will be long term. A large number of widely used file systems either do not offer real-time checks or don't have good ones which will detect an issue before the damage is done, so silent data corruption is a rather common issue on web hosting servers where substantial volumes of information are kept.

No Data Corruption & Data Integrity in Web Hosting

We warrant the integrity of the information uploaded in every single web hosting account which is generated on our cloud platform due to the fact that we use the advanced ZFS file system. The latter is the only one which was designed to prevent silent data corruption via a unique checksum for each and every file. We will store your info on a large number of SSD drives which work in a RAID, so exactly the same files will be present on several places concurrently. ZFS checks the digital fingerprint of all files on all of the drives in real time and in case the checksum of any file differs from what it needs to be, the file system replaces that file with a healthy version from a different drive within the RAID. There's no other file system that uses checksums, so it's easy for data to become silently corrupted and the bad file to be duplicated on all drives over time, but since that can never happen on a server running ZFS, you will not have to worry about the integrity of your data.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

In case you get one of our semi-dedicated hosting solutions, you will not need to be concerned about silent file corruption as we use ZFS - a high level file system that keeps track of all files in real time. Each time you upload a file to your hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synced between several SSD 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 when it detects a corrupted copy, it replaces it with a healthy one from a different drive. This is done instantly, so there will be no risk for any part of your content at any time. By comparison, all of the other file systems perform checks after a system failure, but since they do not use anything similar to the checksums which ZFS uses, they will not detect silently corrupted files, so a corrupted copy could be replicated on the remaining drives as well and you may lose important information. Because this is not the case with ZFS, we guarantee the integrity of each file you upload no matter what.
