Data corruption is the unintentional change of a file or the loss of information which often occurs during reading or writing. The reason could be hardware or software failure, and consequently, a file can become partially or fully corrupted, so it'll no longer function as it should because its bits shall be scrambled or lacking. An image file, for example, will no longer show an authentic image, but a random mix of colors, an archive will be impossible to unpack as its content will be unreadable, etcetera. In case this kind of a problem appears and it's not noticed by the system or by an admin, the data will be corrupted silently and if this happens on a disk drive that's a part of a RAID array where the data is synced between different drives, the corrupted file shall be duplicated on all the other drives and the damage will become permanent. A large number of popular file systems either don't offer real-time checks or do not have good ones which can detect a problem before the damage is done, so silent data corruption is a very common issue on hosting servers where huge amounts of info are stored.
No Data Corruption & Data Integrity in Cloud Hosting
We guarantee the integrity of the data uploaded in any cloud hosting account that is generated on our cloud platform as we work with 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 file. We will store your data on multiple NVMe drives which operate in a RAID, so identical 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 differs from what it has to be, the file system replaces that file with a healthy version from some other drive within the RAID. No other file system uses checksums, so it's possible for data to get silently damaged and the bad file to be duplicated on all drives over time, but since this can never happen on a server using ZFS, you don't have to worry about the integrity of your data.
No Data Corruption & Data Integrity in Semi-dedicated Servers
We've avoided any probability of files getting damaged silently since the servers where your semi-dedicated server account will be created use a powerful file system named ZFS. Its advantage over alternative file systems is that it uses a unique checksum for each file - a digital fingerprint that's checked in real time. As we store all content on numerous NVMe drives, ZFS checks if the fingerprint of a file on one drive matches the one on the other drives and the one it has stored. In case there's a mismatch, the corrupted copy is replaced with a healthy one from one of the other drives and considering that this happens right away, there's no chance that a damaged copy can remain on our web hosting servers or that it could be duplicated to the other hard disks in the RAID. None of the other file systems work with such checks and what is more, even during a file system check right after an unexpected blackout, none of them will detect silently corrupted files. In comparison, ZFS does not crash after a power failure and the continual checksum monitoring makes a lenghty file system check unneeded.
