Data corruption is the accidental change of a file or the losing of info which usually occurs during reading or writing. The reason could be hardware or software fail, and because of this, a file may become partially or fully corrupted, so it'll no longer function correctly since its bits will be scrambled or lacking. An image file, for instance, will no longer present an accurate image, but a random combination of colors, an archive will be impossible to unpack as its content will be unreadable, and so on. If such a problem occurs and it is not found by the system or by an admin, the data will be corrupted silently and when this happens on a disk drive that is part of a RAID array where the info is synced between various different drives, the corrupted file will be copied on all the other drives and the damage will become permanent. Many widely used file systems either don't have real-time checks or don't have high quality ones that will detect an issue before the damage is done, so silent data corruption is a common matter on internet hosting servers where large amounts of info are stored.

No Data Corruption & Data Integrity in Shared Hosting

In case you host your Internet sites in a shared hosting account with our firm, you don't need to worry about your data ever getting damaged. We can guarantee that as our cloud hosting platform works with the revolutionary ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for each and every file. Any kind of data that you upload will be kept in a RAID i.e. simultaneously on many NVMe drives. All of the file systems synchronize the files between the separate drives using such a setup, but there's no real guarantee that a file will not get corrupted. This could occur throughout the writing process on each drive and then a damaged copy can be copied on all other drives. What is different on our platform is the fact that ZFS analyzes the checksums of all files on all drives instantly and in the event that a corrupted file is located, it is replaced with a good copy with the correct checksum from some other drive. That way, your info will continue to be undamaged no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We've avoided any chance of files getting corrupted silently because the servers where your semi-dedicated hosting account will be created use a powerful file system called ZFS. Its main advantage over various other file systems is that it uses a unique checksum for each file - a digital fingerprint that is checked in real time. As we store all content on a number of NVMe drives, ZFS checks whether the fingerprint of a file on one drive corresponds to the one on the other drives and the one it has stored. In case there is a mismatch, the bad copy is replaced with a healthy one from one of the other drives and since this happens instantly, there's no chance that a corrupted copy could remain on our website hosting servers or that it could be copied to the other hard disks in the RAID. None of the other file systems employ this kind of checks and furthermore, even during a file system check following a sudden power failure, none of them can detect silently corrupted files. In contrast, ZFS won't crash after a blackout and the continual checksum monitoring makes a lenghty file system check unneeded.
