Data corruption is the unintentional modification of a file or the losing of info which usually occurs during reading or writing. The reason could be hardware or software fail, and as a consequence, a file can become partially or entirely corrupted, so it will no longer function correctly since its bits shall be scrambled or lacking. An image file, for example, will no longer show an actual image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, etcetera. If such an issue appears and it isn't noticed 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 data is synced between different drives, the corrupted file will be copied on all of the other drives and the damage will become long term. Many widespread file systems either do not have real-time checks or do not have good ones that will detect a problem before the damage is done, so silent data corruption is a common issue on hosting servers where substantial volumes of info are kept.

No Data Corruption & Data Integrity in Cloud Website Hosting

We warrant the integrity of the data uploaded in every cloud website hosting account which is made on our cloud platform because we use the advanced ZFS file system. The latter is the only one which was designed to prevent silent data corruption using a unique checksum for each and every file. We shall store your data on a large number of NVMe drives that work in a RAID, so the very same files will be accessible on several places at once. ZFS checks the digital fingerprint of all files on all the drives in real time and if the checksum of any file differs from what it needs to be, the file system replaces that file with an undamaged copy from another drive inside the RAID. No other file system uses checksums, so it is possible for data to get silently damaged and the bad file to be reproduced on all drives over time, but since this can never happen on a server using ZFS, you don't have to concern yourself with the integrity of your data.
