Data corruption is the unintentional change of a file or the loss of info which usually occurs during reading or writing. The reason can be hardware or software failure, and because of this, a file could become partially or fully corrupted, so it will no longer work correctly because its bits shall be scrambled or lost. An image file, for example, will no longer present 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. If such an issue occurs and it's not found by the system or by an admin, the data will be corrupted silently and in case this happens on a disk drive that is part of a RAID array where the data is synced between various drives, the corrupted file shall be duplicated on all of the other drives and the harm will become permanent. Many commonly used file systems either don't feature real-time checks or don't have high quality ones that can detect an issue before the damage is done, so silent data corruption is a common issue on hosting servers where huge volumes of data are kept.
No Data Corruption & Data Integrity in Shared Hosting
We warrant the integrity of the data uploaded in any shared hosting account that 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 avert silent data corruption via a unique checksum for each and every file. We will store your information on multiple NVMe drives that operate in a RAID, so the same files will exist on several places at the same time. ZFS checks the digital fingerprint of all of the files on all the drives in real time and in case the checksum of any file is different from what it has to be, the file system swaps that file with an undamaged version from some other drive in the RAID. There's no other file system which uses checksums, so it's possible for data to be silently damaged and the bad file to be replicated on all drives over time, but since that can never happen on a server using ZFS, you don't have to concern yourself with the integrity of your data.
No Data Corruption & Data Integrity in Semi-dedicated Servers
You won't experience any kind of silent data corruption issues whatsoever in case you obtain one of our semi-dedicated server plans because the ZFS file system that we employ on our cloud hosting platform uses checksums in order to ensure that all files are undamaged all of the time. A checksum is a unique digital fingerprint which is assigned to each and every file kept on a server. Due to the fact that we store all content on a number of drives at the same time, the same file uses the same checksum on all the drives and what ZFS does is that it compares the checksums between the different drives right away. 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 probability of the corrupted copy to be synchronized on the other hard drives. ZFS is the only file system you can find that uses checksums, which makes it much more dependable than other file systems that cannot detect silent data corruption and copy bad files across drives.
