Data corruption is the unintentional change of a file or the loss of information which often occurs during reading or writing. The reason may be hardware or software fail, and due to this fact, a file can become partially or completely corrupted, so it will no longer work as it should since its bits shall be scrambled or lost. An image file, for instance, will no longer present an accurate image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, etc. In case this kind of an issue occurs and it isn't found by the system or by an admin, the data will get corrupted silently and in case this happens on a drive that's a part of a RAID array where the data is synchronized between different drives, the corrupted file shall be replicated on all of 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 good ones that will detect an issue before the damage is done, so silent data corruption is a rather common problem on internet hosting servers where large volumes of info are kept.

No Data Corruption & Data Integrity in Shared Hosting

We have resolved the issue of silent data corruption on all our shared hosting servers by using the advanced Z file system, or ZFS. The latter is superior to other file systems as it is the only one on the market that checks all the files right away by employing a checksum - a digital identifier that's unique for each and every file. When you upload content to your account, it'll be stored on several NVMe drives and regularly synchronized between them for redundancy. ZFS constantly analyzes the checksum of all files and in case any file is detected as corrupted, it is replaced quickly with a good copy from some other disk. As this happens in real time, there's no risk that a bad file may remain or may be copied on the rest of the NVMes. ZFS requires plenty of physical memory in order to execute the real-time checks and the benefit of our cloud website hosting platform is that we take advantage of multiple very powerful servers working together. In case you host your sites with us, your information will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

If you get one of our semi-dedicated hosting solutions, you won't need to worry about silent file corruption since we use ZFS - a high level file system that keeps track of all of the files in real time. Each time 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 a number of NVMe drives for redundancy, so if a 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 another drive. This happens right away, so there will be no risk for any part of your content at any time. In comparison, all of the other file systems execute checks only after a system breakdown, but since they do not use anything similar to the checksums which ZFS uses, they can't detect silently corrupted files, so a bad copy can be replicated on the rest of the disks as well and you can lose critical info. As this is not the case with ZFS, we're able to guarantee the integrity of each file you upload no matter what.
