Data corruption is the accidental modification of a file or the losing of info that often occurs during reading or writing. The reason can be hardware or software failure, and for that reason, a file can become partially or completely corrupted, so it will no longer work as it should since its bits will be scrambled or missing. An image file, for example, will no longer show a true image, but a random combination 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 admin, the data will be corrupted silently and in case this happens on a disk drive that's a part of a RAID array where the data is synchronized between different drives, the corrupted file shall be copied on all other drives and the damage will be permanent. A large number of widespread file systems either do not offer real-time checks or do not have high quality ones that will detect an issue before the damage is done, so silent data corruption is a very common matter on hosting servers where huge amounts of information are stored.

No Data Corruption & Data Integrity in Shared Hosting

In case you host your sites in a shared hosting account with our firm, you don't need to worry about any of your data ever getting damaged. We can guarantee that since our cloud hosting platform uses the state-of-the-art ZFS file system. The latter is the only file system that works with checksums, or unique digital fingerprints, for each and every file. Any info that you upload will be saved in a RAID i.e. simultaneously on a number of NVMe drives. All the file systems synchronize the files between the different drives using this kind of a setup, but there's no real guarantee that a file will not get corrupted. This may happen throughout the writing process on any drive and after that a corrupted copy may be copied on the other drives. What makes the difference on our platform is the fact that ZFS compares the checksums of all files on all drives in real time and when a corrupted file is identified, it's replaced with a good copy with the correct checksum from another drive. This way, your data will stay undamaged no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You will not need to deal with any silent data corruption issues whatsoever should you get one of our semi-dedicated server solutions due to the fact that the ZFS file system that we employ on our cloud hosting platform uses checksums in order to make sure that all files are undamaged all the time. A checksum is a unique digital fingerprint which is given to each and every file kept on a server. As we store all content on a number of drives at the same time, the same file has the same checksum on all the drives and what ZFS does is that it compares the checksums between the different drives in real time. In case it detects that a file is corrupted and its checksum is different from what it has to be, it replaces that file with a healthy copy right away, avoiding any chance of the damaged copy to be synchronized on the rest of the drives. ZFS is the sole file system you can get that uses checksums, which makes it much more reliable than other file systems that are unable to identify silent data corruption and copy bad files across hard drives.
