Data corruption is the accidental transformation of a file or the loss of info which often occurs during reading or writing. The reason can be hardware or software failure, and consequently, a file can become partially or entirely corrupted, so it will no longer work correctly because its bits will be scrambled or missing. An image file, for instance, will no longer display a real image, but a random mix of colors, an archive will be impossible to unpack as its content will be unreadable, etc. If this kind of an issue occurs and it's not recognized by the system or by an administrator, the data will get corrupted silently and if this happens on a disk drive that is a part of a RAID array where the information is synchronized between different drives, the corrupted file will be reproduced on all of the other drives and the harm will become long term. A large number of widespread file systems either don't offer real-time checks or do not have good ones which can detect an issue before the damage is done, so silent data corruption is a rather common problem on hosting servers where large amounts of info are kept.

No Data Corruption & Data Integrity in Cloud Web Hosting

We warrant the integrity of the info uploaded in each and every cloud web hosting account which is made on our cloud platform because we use the advanced ZFS file system. The latter is the only one which was designed to prevent silent data corruption thanks to a unique checksum for each and every file. We'll store your information on a large number of NVMe drives which operate in a RAID, so the same files will be present on several places concurrently. ZFS checks the digital fingerprint of all the files on all the drives in real time and in case the checksum of any file is different from what it needs to be, the file system replaces that file with a healthy version from another drive within the RAID. There's no other file system which uses checksums, so it is possible for data to become silently corrupted and the bad file to be reproduced on all drives over time, but since that can never happen on a server using ZFS, you will not have to worry about the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We have avoided any risk of files getting damaged silently due to the fact that the servers where your semi-dedicated hosting account will be created work with a powerful file system named ZFS. Its main advantage over other file systems is that it uses a unique checksum for each and every file - a digital fingerprint that's checked in real time. Since we store 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. In case there's a mismatch, the damaged copy is replaced with a good one from one of the other drives and since it happens right away, there is no chance that a corrupted copy could remain on our servers or that it can be duplicated to the other hard drives in the RAID. None of the other file systems include such checks and what's more, even during a file system check following a sudden power failure, none of them can identify silently corrupted files. In comparison, ZFS won't crash after an electrical power failure and the regular checksum monitoring makes a time-consuming file system check obsolete.
