Data corruption is the accidental modification of a file or the loss of info that often occurs during reading or writing. The reason can be hardware or software fail, and for that reason, a file may become partially or completely corrupted, so it will no longer work correctly because its bits will be scrambled or lost. An image file, for example, will no longer show an accurate image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, and so on. In the event that such a problem occurs and it is not recognized by the system or by an admin, the data will become corrupted silently and in case this happens on a disk drive that's part of a RAID array where the info is synchronized between various different drives, the corrupted file shall be replicated on all of the other drives and the damage will become permanent. A number of widespread file systems either do not offer real-time checks or don't have good ones that will detect a problem before the damage is done, so silent data corruption is a common issue on web hosting servers where substantial volumes of information are stored.
No Data Corruption & Data Integrity in Cloud Website Hosting
We guarantee the integrity of the data uploaded in each cloud website hosting
account that is generated on our cloud platform as we employ the advanced ZFS file system. The aforementioned is the only one which was designed to prevent silent data corruption using a unique checksum for every single file. We will store your data on multiple SSD drives which work in a RAID, so the exact same files will be available on several places at once. ZFS checks the digital fingerprint of all files on all drives in real time and if the checksum of any file is different from what it should be, the file system replaces that file with an undamaged version from another drive in the RAID. There's no other file system which uses checksums, so it's possible for data to become silently damaged and the bad file to be reproduced on all drives over time, but since that can never happen on a server using ZFS, you won't have to concern yourself with the integrity of your data.
No Data Corruption & Data Integrity in Semi-dedicated Servers
We have avoided any risk of files getting damaged silently because the servers where your semi-dedicated server
account will be created work with a powerful file system called ZFS. Its main advantage over various other file systems is that it uses a unique checksum for each and every file - a digital fingerprint that's checked in real time. As we store all content on a number of SSD drives, ZFS checks whether the fingerprint of a file on one drive matches the one on the other drives and the one it has stored. In the event that there's a mismatch, the damaged copy is replaced with a healthy one from one of the other drives and because this happens instantly, there's no chance that a corrupted copy can remain on our website hosting servers or that it can be copied to the other hard drives in the RAID. None of the other file systems include this kind of checks and what's more, even during a file system check following a sudden power failure, none of them can find silently corrupted files. In comparison, ZFS will not crash after a power failure and the continual checksum monitoring makes a time-consuming file system check unneeded.
