Data corruption is the accidental transformation of a file or the losing of info that usually occurs during reading or writing. The reason may be hardware or software fail, and due to this fact, a file may become partially or completely corrupted, so it will no longer work correctly because its bits shall be scrambled or missing. An image file, for example, will no longer show an authentic image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, etcetera. When this kind of an issue occurs and it isn't identified by the system or by an administrator, the data will be corrupted silently and in case this happens on a disk drive that is part of a RAID array where the data is synchronized between various different drives, the corrupted file shall be reproduced on all the other drives and the damage will be long term. A number of popular file systems either don't feature real-time checks or don't have high quality ones which will detect an issue before the damage is done, so silent data corruption is a very common problem on web hosting servers where large volumes of info are stored.
No Data Corruption & Data Integrity in Shared Hosting
We guarantee the integrity of the data uploaded in every shared hosting account which is made on our cloud platform due to the fact that we use the advanced ZFS file system. The aforementioned is the only one that was designed to avert silent data corruption using a unique checksum for each and every file. We shall store your data on multiple SSD drives that operate in a RAID, so the same files will be available on several places concurrently. ZFS checks the digital fingerprint of all of the files on all drives in real time and in case the checksum of any file is different from what it should be, the file system replaces that file with a healthy version from another drive inside the RAID. There's no other file system that uses checksums, so it is possible for data to get silently damaged and the bad file to be duplicated on all drives with time, but since that can never happen on a server using ZFS, you will not have to worry about the integrity of your info.
