Data corruption is the unintended change of a file or the losing of info that often occurs during reading or writing. The reason can be hardware or software malfunction, and for that reason, a file may become partially or completely corrupted, so it'll no longer function properly as its bits will be scrambled or lacking. An image file, for instance, will no longer show 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. In case such an issue appears and it is not noticed by the system or by an admin, the data will be corrupted silently and when this happens on a drive that is a part of a RAID array where the information is synced between various drives, the corrupted file shall be replicated on all the other drives and the damage will become permanent. A number of frequently used file systems either don't offer real-time checks or don't have good ones that can detect a problem before the damage is done, so silent data corruption is a rather common matter on internet hosting servers where huge volumes of information are kept.

No Data Corruption & Data Integrity in Cloud Hosting

The integrity of the data which you upload to your new cloud hosting account will be ensured by the ZFS file system which we make use of on our cloud platform. Most web hosting suppliers, including our company, use multiple HDDs to store content and because the drives work in a RAID, exactly the same data is synchronized between the drives all the time. When a file on a drive gets damaged for some reason, however, it is likely that it will be reproduced on the other drives because alternative file systems do not have special checks for that. In contrast to them, ZFS works with a digital fingerprint, or a checksum, for every single file. In the event that a file gets damaged, its checksum will not match what ZFS has as a record for it, which means that the bad copy will be replaced with a good one from another drive. Because this happens instantly, there is no possibility for any of your files to ever get corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We have avoided any chance of files getting corrupted silently due to the fact that the servers where your semi-dedicated hosting account will be created work with a powerful file system named ZFS. Its basic advantage over alternative file systems is that it uses a unique checksum for each file - a digital fingerprint which is checked in real time. As we save all content on a number of SSD drives, ZFS checks whether 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 damaged copy is replaced with a good one from one of the other drives and considering that it happens right away, there is no chance that a corrupted copy could remain on our hosting servers or that it can be duplicated to the other hard drives in the RAID. None of the other file systems include such checks and in addition, even during a file system check right after a sudden electrical power failure, none of them will discover silently corrupted files. In contrast, ZFS won't crash after a power loss and the continual checksum monitoring makes a time-consuming file system check unnecessary.
