Data corruption is the unintentional change of a file or the loss of info which usually occurs during reading or writing. The reason can be hardware or software failure, and as a consequence, a file may become partially or entirely corrupted, so it'll no longer work correctly as its bits will be scrambled or missing. An image file, for instance, will no longer show a true image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, etcetera. If such a problem occurs and it's not recognized by the system or by an administrator, the data will get corrupted silently and when this happens on a disk drive that is a part of a RAID array where the info is synced between different drives, the corrupted file shall be duplicated on all the other drives and the harm will become permanent. A large number of popular file systems either don't have real-time checks or don't have good ones that can detect a problem before the damage is done, so silent data corruption is a common problem on web hosting servers where large amounts of data are kept.
No Data Corruption & Data Integrity in Hosting
We warrant the integrity of the information uploaded in each hosting account which is made on our cloud platform as we work with the advanced ZFS file system. The latter is the only one which was designed to avoid silent data corruption through a unique checksum for each file. We will store your data on a number of NVMe drives that work in a RAID, so exactly the same files will exist on several places concurrently. ZFS checks the digital fingerprint of all files on all drives in real time and in the event that the checksum of any file differs from what it has to be, the file system swaps that file with a healthy version from a different drive from the RAID. No other file system uses checksums, so it's easy for data to become silently corrupted and the bad file to be reproduced on all drives over time, but since that can never happen on a server running ZFS, you will not have to concern yourself with the integrity of your data.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You will not need to deal with any kind of silent data corruption issues if you buy one of our semi-dedicated hosting plans as the ZFS file system that we work with on our cloud hosting platform uses checksums to guarantee that all of your files are intact all of the time. A checksum is a unique digital fingerprint which is allotted to each and every file saved on a server. Because we store all content on multiple drives simultaneously, the same file uses the same checksum on all of the drives and what ZFS does is that it compares the checksums between the different drives right away. If 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 damaged copy to be synchronized on the remaining hard disks. ZFS is the only file system on the market which uses checksums, which makes it far superior to other file systems that cannot identify silent data corruption and duplicate bad files across hard drives.
