Data corruption is the accidental change of a file or the loss of info that often occurs during reading or writing. The reason could be hardware or software fail, and as a result, a file may become partially or completely corrupted, so it'll no longer function correctly as its bits shall be scrambled or lost. An image file, for instance, will no longer display a real image, but a random mix of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etc. When this kind of an issue occurs and it's not identified by the system or by an admin, the data will become corrupted silently and when this happens on a disk drive which is a part of a RAID array where the information is synced between different drives, the corrupted file shall be copied on all of the other drives and the harm will become long term. Numerous widespread file systems either don't have real-time checks or don't have high quality ones which can detect a problem before the damage is done, so silent data corruption is a rather common problem on internet hosting servers where huge amounts of info are stored.
No Data Corruption & Data Integrity in Cloud Web Hosting
We've dealt with the problem of silent data corruption on all of our cloud web hosting servers by using the cutting-edge Z file system, or ZFS. The latter is better than other file systems since it is the only one in existence that checks all files immediately by employing a checksum - a digital identifier that is unique for each file. When you upload content to your account, it'll be stored on several NVMe drives and continually synchronized between them for redundancy. ZFS regularly analyzes the checksum of all files and in the event that any file is detected as corrupted, it is replaced instantly with a good copy from some other disk. As this happens in real time, there's no risk that a corrupted file may remain or may be copied on the remaining NVMes. ZFS needs plenty of physical memory in order to perform the real-time checks and the benefit of our cloud hosting platform is that we work with multiple very powerful servers working together. In case you host your websites with us, your info will be intact no matter what.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You won't have to deal with any kind of silent data corruption issues whatsoever if you obtain one of our semi-dedicated hosting solutions as the ZFS file system that we use on our cloud hosting platform uses checksums to ensure that all of the files are undamaged at all times. A checksum is a unique digital fingerprint which is assigned to each and every file saved on a server. Since we store all content on multiple drives at the same time, the same file has the same checksum on all the drives and what ZFS does is that it compares the checksums between the different drives in real time. If 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 bad copy to be synchronized on the other drives. ZFS is the only file system you can get which uses checksums, which makes it much more reliable than other file systems which cannot detect silent data corruption and duplicate bad files across hard drives.
