Data corruption is the accidental change of a file or the loss of info which usually occurs during reading or writing. The reason may be hardware or software fail, and as a result, a file may become partially or completely corrupted, so it'll no longer function as it should since its bits shall be scrambled or lost. An image file, for example, will no longer present an accurate image, but a random mix of colors, an archive will be impossible to unpack as its content will be unreadable, and so on. When such an issue appears and it is not found by the system or by an admin, the data will become corrupted silently and in case this happens on a disk drive that's a part of a RAID array where the data is synced between various drives, the corrupted file will be copied on all of the other drives and the harm will be long term. A large number of popular file systems either don't feature real-time checks or don't have high quality ones which will detect an issue before the damage is done, so silent data corruption is a common issue on internet hosting servers where large amounts of data are kept.
No Data Corruption & Data Integrity in Web Hosting
If you host your websites in a web hosting
account with our firm, you won't need to worry about any of your data ever getting damaged. We can ensure that due to the fact that our cloud hosting platform uses the amazing ZFS file system. The aforementioned is the only file system which works with checksums, or unique digital fingerprints, for every single file. Any information that you upload will be stored in a RAID i.e. simultaneously on many different SSD drives. Many file systems synchronize the files between the separate drives using this type of a setup, but there is no real guarantee that a file will not be corrupted. This could happen at the time of the writing process on each drive and then a corrupted copy can be copied on the rest of the drives. What makes the difference on our platform is the fact that ZFS examines the checksums of all files on all of the drives right away and in case a corrupted file is located, it's substituted with a good copy with the correct checksum from another drive. This way, your information will stay intact no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Servers
We've avoided any chance of files getting damaged silently due to the fact that the servers where your semi-dedicated server
account will be created employ a powerful file system known as ZFS. Its basic advantage over other file systems is that it uses a unique checksum for each and every file - a digital fingerprint that is checked in real time. As we keep all content on numerous SSD 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. In the event that there's a mismatch, the corrupted copy is replaced with a good one from one of the other drives and since it happens instantly, there is no chance that a corrupted copy could remain on our website hosting servers or that it could be copied to the other hard drives in the RAID. None of the other file systems include such checks and what's more, even during a file system check right after a sudden power loss, none of them can find silently corrupted files. In comparison, ZFS doesn't crash after an electrical power failure and the regular checksum monitoring makes a lenghty file system check unnecessary.
