Data corruption is the unintentional modification of a file or the losing of info that usually occurs during reading or writing. The reason may be hardware or software failure, and consequently, a file could become partially or completely corrupted, so it'll no longer function properly because its bits will be scrambled or lacking. An image file, for instance, will no longer show a real image, but a random combination of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etc. In case such an issue appears and it's not noticed by the system or by an admin, the data will be corrupted silently and if this happens on a disk drive which is part of a RAID array where the information is synchronized between different drives, the corrupted file will be duplicated on all the other drives and the harm will become permanent. A large number of widespread file systems either don't have real-time checks or don't have high quality ones that can detect a problem before the damage is done, so silent data corruption is a very common problem on hosting servers where huge amounts of info are stored.

No Data Corruption & Data Integrity in Cloud Hosting

In case you host your Internet sites in a cloud hosting account from our firm, you do not need to worry about your data ever getting damaged. We can ensure that because our cloud hosting platform works with the state-of-the-art ZFS file system. The latter is the only file system that uses checksums, or unique digital fingerprints, for each file. All info that you upload will be saved in a RAID i.e. simultaneously on many NVMes. Many file systems synchronize the files between the different drives using this kind of a setup, but there is no real warranty that a file won't be corrupted. This could happen at the time of the writing process on each drive and after that a bad copy may be copied on all other drives. What is different on our platform is that ZFS examines the checksums of all files on all drives immediately and when a corrupted file is discovered, it is substituted with a good copy with the correct checksum from another drive. In this way, your data will stay unharmed no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

In case you acquire one of our semi-dedicated hosting plans, you won't need to worry about silent file corruption because we use ZFS - an advanced file system which keeps track of all the files in real time. Whenever you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synced between a number of NVMe drives for redundancy, so if a drive fails, the other ones will take over. ZFS compares the checksum of all copies on the different drives and when it detects a damaged copy, it replaces it with a healthy one from another drive. This is done instantly, so there will be no danger for any part of your content at any moment. By comparison, alternative file systems carry out checks after a system failure, but since they don't use anything similar to the checksums which ZFS uses, they will not detect silently corrupted files, so a corrupted copy may be replicated on the rest of the drives as well and you can lose critical info. As this is not the case with ZFS, we warrant the integrity of each and every file you upload no matter what.
