Data corruption is the unintended change of a file or the loss of info that often occurs during reading or writing. The reason could be hardware or software malfunction, and for that reason, a file may become partially or completely corrupted, so it'll no longer function as it should as its bits shall be scrambled or missing. An image file, for example, will no longer display an accurate image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, etcetera. If such an issue appears and it is not identified by the system or by an admin, the data will be corrupted silently and if this happens on a disk drive which is a part of a RAID array where the data is synced between different drives, the corrupted file will be duplicated on all of the other drives and the harm will become permanent. Numerous commonly used file systems either do not have real-time checks or don't have high quality ones which can detect an issue before the damage is done, so silent data corruption is a very common matter on internet hosting servers where substantial amounts of information are stored.
No Data Corruption & Data Integrity in Hosting
We warrant the integrity of the information uploaded in any hosting
account which is made on our cloud platform because we employ the advanced ZFS file system. The aforementioned is the only one which was designed to avert silent data corruption through a unique checksum for each file. We shall store your information on a number of SSD drives that operate in a RAID, so the same files will be available on several places at the same time. ZFS checks the digital fingerprint of all the files on all the drives in real time and if the checksum of any file differs from what it should be, the file system replaces that file with an undamaged copy from some other drive inside the RAID. No other file system uses checksums, so it's easy for data to be silently damaged and the bad file to be duplicated on all drives over time, but since this can never happen on a server using ZFS, you won't have to concern yourself with the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You won't need to deal with any silent data corruption issues whatsoever should you acquire one of our semi-dedicated hosting
solutions as the ZFS file system that we use on our cloud hosting platform uses checksums in order to make sure that all the files are undamaged at all times. A checksum is a unique digital fingerprint that is assigned to each and every file kept on a server. Due to the fact that we store all content on multiple drives simultaneously, the same file has the same checksum on all of the 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 should be, it replaces that file with a healthy copy without delay, avoiding any probability of the corrupted copy to be synchronized on the remaining drives. ZFS is the only file system available on the market which uses checksums, which makes it much more dependable than other file systems that cannot detect silent data corruption and copy bad files across hard drives.
