Data corruption is the accidental transformation of a file or the loss of information that often occurs during reading or writing. The reason may be hardware or software malfunction, and due to this fact, a file can become partially or entirely corrupted, so it will no longer work 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 since its content will be unreadable, etc. In the event that such a problem occurs and it is not found by the system or by an administrator, the data will become corrupted silently and if this happens on a drive that is part of a RAID array where the info is synced between various drives, the corrupted file shall be reproduced on all the other drives and the harm will be long term. Numerous widely used file systems either don't feature 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 common matter on internet hosting servers where substantial amounts of data are kept.
No Data Corruption & Data Integrity in Shared Hosting
If you host your Internet sites in a shared hosting account with our firm, you won't have to worry about your data ever getting corrupted. We can guarantee that as our cloud hosting platform uses the outstanding ZFS file system. The aforementioned is the only file system that works with checksums, or unique digital fingerprints, for every single file. Any data that you upload will be saved in a RAID i.e. simultaneously on many different SSDs. All file systems synchronize the files between the different drives with such a setup, but there's no real warranty that a file won't be corrupted. This could happen throughout the writing process on each drive and afterwards a bad copy can be copied on the rest of the drives. What is different on our platform is that ZFS analyzes the checksums of all files on all the drives immediately and in case a corrupted file is discovered, it's swapped with a good copy with the correct checksum from another drive. That way, your info will stay intact 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 since the servers where your semi-dedicated hosting account will be created work with a powerful file system named ZFS. Its main advantage over other file systems is that it uses a unique checksum for each file - a digital fingerprint that is checked in real time. As we keep all content on multiple SSD drives, ZFS checks if the fingerprint of a file on one drive matches the one on the remaining drives and the one it has saved. When there's a mismatch, the corrupted copy is replaced with a good one from one of the other drives and since this happens in real time, there's no chance that a corrupted copy could remain on our web hosting servers or that it could be copied to the other hard drives in the RAID. None of the other file systems use this kind of checks and in addition, even during a file system check right after an unexpected blackout, none of them will detect silently corrupted files. In comparison, ZFS won't crash after a power failure and the constant checksum monitoring makes a time-consuming file system check unnecessary.
