No Data Corruption & Data Integrity
See what No Data Corruption & Data Integrity is and how it can be beneficial for the files within your website hosting account.
Data corruption is the damage of information caused by various software or hardware problems. The moment a file is corrupted, it will no longer work correctly, so an app will not start or will give errors, a text file can be partially or entirely unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of info getting damaged without any acknowledgement by the system or an admin, that makes it a significant problem for website hosting servers as failures are more likely to occur on larger in size hard drives where large volumes of info are located. When a drive is a part of a RAID and the information on it is replicated on other drives for redundancy, it's likely that the damaged file will be treated as a healthy one and will be duplicated on all the drives, making the damage permanent. Lots of the file systems that run on web servers today often are unable to discover corrupted files right away or they need time-consuming system checks during which the server isn't working.
No Data Corruption & Data Integrity in Shared Hosting
We have resolved the issue of silent data corruption on our shared hosting servers by using the amazing Z file system, or ZFS. The latter is more advanced than other file systems as it is the only one on the market that checks all of the files right away by using 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 constantly synchronized between them for redundancy. ZFS constantly analyzes the checksum of all files and when any file is detected as damaged, it is replaced right away with a good copy from some other disk. As this happens in real time, there's no risk that a bad file may remain or may be duplicated on the other NVMes. ZFS needs plenty of physical memory in order to carry out the real-time checks and the benefit of our cloud hosting platform is that we use multiple powerful servers working together. In case you host your websites with us, your data will be undamaged no matter what.
