Data corruption is the unintended change of a file or the losing of info that often occurs during reading or writing. The reason can be hardware or software malfunction, and for that reason, a file can become partially or completely corrupted, so it will no longer function as it should because its bits will be scrambled or missing. An image file, for example, will no longer display a real image, but a random mix of colors, an archive will be impossible to unpack since its content will be unreadable, etc. In case this kind of an issue appears and it isn't noticed by the system or by an administrator, the data will get corrupted silently and in case this happens on a drive that is a part of a RAID array where the information is synced between various different drives, the corrupted file shall be duplicated on all of the other drives and the damage will be permanent. Numerous popular file systems either do not offer real-time checks or do not have good ones which will detect an issue before the damage is done, so silent data corruption is a 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 websites in a shared hosting account from our firm, you won't have to worry about any of your data ever getting corrupted. We can ensure that as our cloud hosting platform uses the cutting-edge ZFS file system. The latter is the only file system that works with checksums, or unique digital fingerprints, for each file. All of the data that you upload will be kept in a RAID i.e. simultaneously on many NVMe drives. A lot of file systems synchronize the files between the different drives with this type of a setup, but there is no real warranty that a file will not get corrupted. This may occur at the time of the writing process on any drive and after that a bad copy may be copied on the rest of the drives. What is different on our platform is the fact that ZFS analyzes the checksums of all files on all drives right away and when a corrupted file is identified, it is replaced with a good copy with the correct checksum from another drive. That way, your data will remain undamaged no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We've avoided any chance of files getting damaged silently as the servers where your semi-dedicated hosting account will be created take advantage of a powerful file system called ZFS. Its basic advantage over other file systems is that it uses a unique checksum for each file - a digital fingerprint which is checked in real time. As we store all content on multiple NVMe drives, ZFS checks if the fingerprint of a file on one drive corresponds to the one on the other drives and the one it has saved. If there's a mismatch, the damaged copy is replaced with a healthy one from one of the other drives and since this happens in real time, there is no chance that a damaged copy can remain on our servers or that it could be duplicated to the other hard disks in the RAID. None of the other file systems work with this type of checks and furthermore, even during a file system check after a sudden power loss, none of them will identify silently corrupted files. In contrast, ZFS doesn't crash after a blackout and the constant checksum monitoring makes a time-consuming file system check unnecessary.
