Data corruption is the accidental change of a file or the losing of info which usually occurs during reading or writing. The reason can be hardware or software malfunction, and because of this, a file can become partially or entirely corrupted, so it will no longer function properly as its bits shall be scrambled or missing. An image file, for instance, will no longer display a true image, but a random combination of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etcetera. In the event that this kind of a problem occurs and it's not noticed by the system or by an admin, the data will become corrupted silently and when this happens on a drive which is part of a RAID array where the data is synced between various different drives, the corrupted file shall be copied on all the other drives and the damage will be long term. Numerous popular file systems either don't have real-time checks or don't have good ones that can detect an issue before the damage is done, so silent data corruption is a common matter on web hosting servers where large volumes of info are kept.
No Data Corruption & Data Integrity in Cloud Web Hosting
We guarantee the integrity of the information uploaded in any cloud web hosting account that is made on our cloud platform as we work with the advanced ZFS file system. The aforementioned is the only one which was designed to avoid silent data corruption through a unique checksum for every single file. We shall store your data on a number of NVMe drives which function in a RAID, so the very same files will be available on several places at once. ZFS checks the digital fingerprint of all the files on all of the drives in real time and in the event that the checksum of any file is different from what it has to be, the file system swaps that file with a healthy copy from a different drive inside the RAID. No other file system uses checksums, so it's possible for data to be silently damaged and the bad file to be reproduced on all drives with time, but since this can never happen on a server running ZFS, you will not have to concern yourself with the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You will not have to deal with any silent data corruption issues if you purchase one of our semi-dedicated hosting packages as the ZFS file system that we employ on our cloud hosting platform uses checksums in order to ensure that all the files are undamaged all of the time. A checksum is a unique digital fingerprint which is allotted to each and every file stored on a server. Due to the fact that we store all content on multiple drives at the same time, the same file has the same checksum on all drives and what ZFS does is that it compares the checksums between the different drives right away. When it detects that a file is corrupted and its checksum is different from what it has to be, it replaces that file with a healthy copy without delay, avoiding any probability of the corrupted copy to be synchronized on the rest of the hard disks. ZFS is the only file system out there that uses checksums, which makes it much more reliable than other file systems which cannot identify silent data corruption and duplicate bad files across hard drives.
