Data corruption is the unintended transformation of a file or the losing of info which often occurs during reading or writing. The reason could be hardware or software fail, and because of this, a file could become partially or completely corrupted, so it'll no longer function as it should as its bits shall be scrambled or lost. An image file, for example, will no longer display an accurate image, but a random mix of colors, an archive will be impossible to unpack since its content will be unreadable, and so on. When this kind of an issue occurs and it's not noticed by the system or by an administrator, the data will be corrupted silently and when this happens on a drive that is part of a RAID array where the data is synced between various different drives, the corrupted file shall be replicated on all other drives and the damage will become permanent. A number of widespread file systems either do not have real-time checks or don't have good ones which can detect an issue before the damage is done, so silent data corruption is a rather common matter on hosting servers where large amounts of information are kept.
No Data Corruption & Data Integrity in Cloud Website Hosting
The integrity of the data which you upload to your new cloud website hosting
account will be ensured by the ZFS file system that we make use of on our cloud platform. The vast majority of internet hosting suppliers, including our firm, use multiple hard disk drives to store content and since the drives work in a RAID, the same data is synchronized between the drives at all times. In case a file on a drive is damaged for reasons unknown, however, it is likely that it will be reproduced on the other drives since alternative file systems don't feature special checks for this. In contrast to them, ZFS works with a digital fingerprint, or a checksum, for every single file. In case a file gets corrupted, its checksum will not match what ZFS has as a record for it, so the damaged copy shall be swapped with a good one from a different hard disk. Because this happens right away, there's no possibility for any of your files to ever be damaged.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
We've avoided any chance of files getting damaged silently because the servers where your semi-dedicated hosting
account will be created work with a powerful file system named ZFS. Its advantage over various other file systems is that it uses a unique checksum for every single file - a digital fingerprint that's checked in real time. As we save all content on numerous SSD drives, ZFS checks if the fingerprint of a file on one drive matches the one on the other drives and the one it has stored. When there's a mismatch, the corrupted copy is replaced with a healthy one from one of the other drives and since this happens instantly, there is no chance that a damaged copy could remain on our hosting servers or that it can be copied to the other drives in the RAID. None of the other file systems employ such checks and what is more, even during a file system check right after an unexpected electrical power failure, none of them can discover silently corrupted files. In contrast, ZFS doesn't crash after an electrical power failure and the continual checksum monitoring makes a time-consuming file system check unnecessary.
