Data corruption is the unintentional modification of a file or the losing of information that usually occurs during reading or writing. The reason can be hardware or software fail, and consequently, a file could become partially or fully corrupted, so it will no longer function as it should since its bits will be scrambled or lost. An image file, for instance, will no longer present an actual image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, and so on. In the event that such a problem appears and it is not recognized by the system or by an administrator, the data will become 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 will be duplicated on all of the other drives and the harm will become long term. A number of widespread file systems either don't feature real-time checks or don't have high quality ones that will detect a problem before the damage is done, so silent data corruption is a common issue on hosting servers where large amounts of data are kept.

No Data Corruption & Data Integrity in Shared Hosting

We warrant the integrity of the data uploaded in each shared hosting account that is made on our cloud platform since we work with the advanced ZFS file system. The latter is the only one that was designed to avoid silent data corruption using a unique checksum for each file. We shall store your data on a large number of NVMe drives which function in a RAID, so exactly the same files will exist on several places at once. ZFS checks the digital fingerprint of all of the files on all 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 a healthy version from another drive inside the RAID. No other file system uses checksums, so it's possible for data to be silently damaged and the bad file to be duplicated on all drives over time, but since that can never happen on a server running ZFS, you will not have to concern yourself with the integrity of your information.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We've avoided any chance of files getting corrupted silently because the servers where your semi-dedicated hosting account will be created employ a powerful file system known as ZFS. Its basic advantage over various other file systems is that it uses a unique checksum for each file - a digital fingerprint that is checked in real time. Since we keep all content on a number of NVMe drives, ZFS checks if the fingerprint of a file on one drive matches the one on the remaining drives and the one it has saved. When there is a mismatch, the bad copy is replaced with a good one from one of the other drives and because it happens instantly, there's no chance that a corrupted copy could remain on our website hosting servers or that it could be copied to the other hard disks in the RAID. None of the other file systems work with this type of checks and what is more, even during a file system check right after a sudden blackout, none of them will discover silently corrupted files. In contrast, ZFS will not crash after a power loss and the continual checksum monitoring makes a lenghty file system check unnecessary.
