Data corruption is the accidental modification of a file or the losing of info that usually occurs during reading or writing. The reason could be hardware or software fail, and due to this fact, a file may become partially or entirely corrupted, so it'll no longer work correctly since its bits shall be scrambled or lost. An image file, for instance, will no longer show an authentic image, but a random combination of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etc. If this kind of a problem appears and it isn't found by the system or by an admin, the data will become corrupted silently and when this happens on a disk drive that's part of a RAID array where the data is synced between various different drives, the corrupted file shall be replicated on all other drives and the damage will become permanent. Many frequently used file systems either don't feature real-time checks or do not have good ones which will detect an issue before the damage is done, so silent data corruption is a very common issue on web hosting servers where large amounts of data are kept.

No Data Corruption & Data Integrity in Cloud Website Hosting

We have resolved the matter of silent data corruption on all our cloud website hosting servers by using the modern Z file system, or ZFS. The latter is better than other file systems as it is the only one out there which checks all of the files instantly by using a checksum - a digital identifier which is unique for each file. When you upload content to your account, it will be stored on several NVMe drives and frequently synchronized between them for redundancy. ZFS constantly analyzes the checksum of all files and in case any file is detected as corrupted, it's replaced quickly with a good copy from some other disk. As this happens in real time, there is no risk that a corrupted file may remain or may be duplicated on the remaining NVMes. ZFS needs a lot of physical memory in order to perform the real-time checks and the benefit of our cloud hosting platform is that we employ multiple very powerful servers working together. If you host your Internet sites with us, your info will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You won't need to deal with any kind of silent data corruption issues in case you buy one of our semi-dedicated server packages due to the fact that the ZFS file system that we work with on our cloud hosting platform uses checksums to guarantee that all files are undamaged at all times. A checksum is a unique digital fingerprint that is given to each and every file stored on a server. Since we store all content on a number of 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 in real time. In case 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 right away, avoiding any possibility of the corrupted copy to be synchronized on the rest of the drives. ZFS is the only file system available on the market which uses checksums, which makes it far superior to other file systems which are unable to identify silent data corruption and copy bad files across hard drives.
