Data corruption is the unintended change of a file or the losing of info that usually occurs during reading or writing. The reason could be hardware or software failure, and due to this fact, a file could become partially or fully corrupted, so it will no longer work as it should because its bits shall be scrambled or missing. An image file, for instance, will no longer present an accurate image, but a random combination of colors, an archive will be impossible to unpack as its content will be unreadable, and so on. If this kind of an issue appears and it is not noticed by the system or by an admin, the data will become corrupted silently and when this happens on a disk drive that's part of a RAID array where the data is synchronized between different drives, the corrupted file shall be copied on all the other drives and the damage will be permanent. A number of commonly used file systems either do not have real-time checks or do not have high quality ones which can detect an issue before the damage is done, so silent data corruption is a common issue on internet hosting servers where huge volumes of info are stored.

No Data Corruption & Data Integrity in Website Hosting

We warrant the integrity of the info uploaded in each and every website hosting account that is created on our cloud platform because we employ the advanced ZFS file system. The aforementioned is the only one which was designed to prevent silent data corruption through a unique checksum for each file. We shall store your data on a number of NVMe drives which operate in a RAID, so the very same files will be present on several places at the same time. ZFS checks the digital fingerprint of all files on all of the drives in real time and in the event that the checksum of any file differs from what it should be, the file system replaces that file with an undamaged copy from a different drive inside the RAID. No other file system uses checksums, so it is possible for data to get silently damaged and the bad file to be replicated on all drives with time, but since this can never happen on a server running ZFS, you will not have to worry about the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

You will not have to deal with any silent data corruption issues whatsoever should you get one of our semi-dedicated hosting plans due to the fact that the ZFS file system that we work with on our cloud hosting platform uses checksums in order to guarantee that all files are intact at all times. A checksum is a unique digital fingerprint which is allotted to each and every file stored on a server. As we store all content on multiple drives at the same time, the same file uses the same checksum on all of the drives and what ZFS does is that it compares the checksums between the different drives in real time. In case it detects that a file is corrupted and its checksum is different from what it should be, it replaces that file with a healthy copy without delay, avoiding any possibility of the bad copy to be synchronized on the remaining hard disks. ZFS is the sole file system you can get which uses checksums, which makes it much more reliable than other file systems that are not able to detect silent data corruption and copy bad files across drives.
