Data corruption is the unintended change of a file or the loss of info which often occurs during reading or writing. The reason can be hardware or software malfunction, and as a result, a file can become partially or fully corrupted, so it will no longer function correctly because its bits shall be scrambled or missing. An image file, for example, will no longer show a real image, but a random combination of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, and so on. In the event that such an issue appears and it isn't identified by the system or by an administrator, the data will be corrupted silently and if this happens on a disk drive that is part of a RAID array where the data is synced between various different drives, the corrupted file shall be duplicated on all the other drives and the damage will be permanent. Numerous widely used file systems either don't feature real-time checks or do not have good ones that can detect an issue before the damage is done, so silent data corruption is a very common matter on web hosting servers where substantial amounts of information are stored.

No Data Corruption & Data Integrity in Cloud Web Hosting

We have tackled the problem of silent data corruption on all our cloud web hosting servers by using the modern Z file system, or ZFS. The latter is superior to other file systems since it is the only one on the market which checks all of the files immediately by using 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 synced between them for redundancy. ZFS regularly compares the checksum of all files and when any file is detected as damaged, it is replaced quickly with a good copy from another disk. As this happens in real time, there's no risk that a damaged file may remain or may be copied on the remaining NVMes. ZFS requires a lot of physical memory to perform the real-time checks and the benefit of our cloud web hosting platform is that we take advantage of multiple powerful servers working together. If you host your Internet sites with us, your info will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

In case you purchase one of our semi-dedicated server plans, you will not need to worry about silent file corruption since we use ZFS - a high level file system that checks all 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 synchronized between multiple NVMe drives for redundancy, so if one drive fails, the other ones will take over. ZFS compares the checksum of all the copies on the different drives and when it detects a damaged copy, it replaces it with a healthy one from another drive. This is done right away, so there will be no threat for any part of your content at any time. In contrast, other file systems carry out checks only 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 can lose important info. As this isn't the case with ZFS, we guarantee the integrity of each file you upload no matter what.
