No Data Corruption & Data Integrity
What does the 'No Data Corruption & Data Integrity' slogan mean to each hosting account user?
Data corruption is the accidental change of a file or the loss of info which usually occurs during reading or writing. The reason can 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 lacking. An image file, for instance, will no longer present an actual image, but a random combination of colors, an archive will be impossible to unpack as its content will be unreadable, etc. When this kind of a problem occurs and it isn't found by the system or by an administrator, the data will become 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 drives, the corrupted file shall be copied on all other drives and the damage will be permanent. Many commonly used file systems either do not offer real-time checks or do not have high quality ones which will detect a problem before the damage is done, so silent data corruption is a rather common issue on web hosting servers where large amounts of info are stored.
No Data Corruption & Data Integrity in Cloud Web Hosting
We have dealt with the problem of silent data corruption on all our cloud web hosting servers by using the cutting-edge Z file system, or ZFS. The latter is better than other file systems because it is the only one in existence that checks all of the files in real time by using a checksum - a digital identifier that is unique for every single file. When you upload content to your account, it will be stored on several NVMe drives and constantly synchronized between them for redundancy. ZFS regularly compares the checksum of all files and if any file is detected as damaged, it is replaced instantly with a good copy from another disk. As this happens in real time, there is no risk that a bad 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 advantage of our cloud web hosting platform is that we work with multiple very powerful servers working together. If you host your Internet sites with us, your data will be intact no matter what.
