Data corruption is the unintended transformation of a file or the loss of info that often occurs during reading or writing. The reason could be hardware or software failure, and as a consequence, a file can become partially or completely corrupted, so it will no longer work properly as its bits shall be scrambled or missing. An image file, for example, will no longer display a true image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, etcetera. In case such a problem occurs and it isn't found by the system or by an admin, the data will become corrupted silently and if this happens on a drive that is part of a RAID array where the information is synchronized between different drives, the corrupted file shall be duplicated on all the other drives and the damage will be permanent. A number of frequently used file systems either do not feature real-time checks or don't have high quality ones which will detect a problem before the damage is done, so silent data corruption is a rather common matter on hosting servers where substantial volumes of data are stored.
No Data Corruption & Data Integrity in Cloud Hosting
We guarantee the integrity of the data uploaded in each cloud hosting account which is generated on our cloud platform because we employ the advanced ZFS file system. The aforementioned is the only one which was designed to prevent silent data corruption via a unique checksum for every single file. We'll store your data on a large number of SSD drives which operate in a RAID, so identical files will be available on several places at the same time. ZFS checks the digital fingerprint of all files on all 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 an undamaged copy from some other drive inside the RAID. No other file system uses checksums, so it is easy for data to get silently corrupted and the bad file to be duplicated on all drives over time, but since that can never happen on a server using ZFS, you will not have to worry about the integrity of your information.
