Data corruption is the accidental change of a file or the losing of information which often occurs during reading or writing. The reason can be hardware or software fail, and for that reason, a file could become partially or fully corrupted, so it will no longer work properly as its bits will be scrambled or lacking. An image file, for example, will no longer present an authentic image, but a random combination of colors, an archive will be impossible to unpack as its content will be unreadable, etc. When such an issue appears and it isn't noticed by the system or by an administrator, the data will become corrupted silently and when this happens on a drive which is part of a RAID array where the information is synchronized between various drives, the corrupted file shall be duplicated on all other drives and the harm will become long term. Numerous widespread 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 rather common problem on internet hosting servers where huge amounts of info are stored.

No Data Corruption & Data Integrity in Shared Hosting

We have resolved the matter of silent data corruption on all our shared hosting servers by using the cutting-edge Z file system, or ZFS. The latter is more advanced than other file systems because it is the only one on the market that checks all files in real time by employing a checksum - a digital identifier that's unique for every single file. When you upload content to your account, it will be stored on several NVMe drives and frequently synchronized between them for redundancy. ZFS constantly examines the checksum of all files and if any file is detected as damaged, it's replaced immediately with a good copy from some other disk. As this happens in real time, there's no risk that a damaged file may remain or may be copied on the remaining NVMes. ZFS needs plenty of physical memory in order to execute the real-time checks and the advantage of our cloud website hosting platform is that we work with multiple powerful servers working together. If you host your websites with us, your info will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We've avoided any chance of files getting corrupted silently as the servers where your semi-dedicated hosting account will be created work with a powerful file system called ZFS. Its key advantage over alternative file systems is that it uses a unique checksum for every single file - a digital fingerprint that is checked in real time. Since we save all content on numerous NVMe drives, ZFS checks if the fingerprint of a file on one drive corresponds to the one on the rest of the drives and the one it has stored. If there's a mismatch, the damaged copy is replaced with a good one from one of the other drives and considering that it happens instantly, there is no chance that a corrupted copy can remain on our hosting servers or that it could be copied to the other drives in the RAID. None of the other file systems employ this type of checks and what's more, even during a file system check after a sudden electrical 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 lenghty file system check unneeded.
