Data corruption is the damage of data caused by various hardware or software fails. After a file gets damaged, it will no longer work correctly, so an application will not start or will give errors, a text file shall be partially or entirely unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of data getting damaged without any acknowledgement by the system or an administrator, that makes it a serious problem for web hosting servers as fails are very likely to happen on larger in size hard disks where substantial volumes of info are placed. In case a drive is a part of a RAID and the information on it is duplicated on other drives for redundancy, it's more than likely that the damaged file will be treated as a regular one and it'll be copied on all the drives, making the damage permanent. Lots of the file systems that operate on web servers today often cannot find corrupted files instantly or they need time-consuming system checks during which the server isn't working.
No Data Corruption & Data Integrity in Cloud Hosting
We guarantee the integrity of the info uploaded in each cloud hosting account which is created on our cloud platform due to the fact that we work with the advanced ZFS file system. The aforementioned is the only one that was designed to avoid silent data corruption using a unique checksum for every single file. We will store your information on a number of NVMe drives that operate in a RAID, so the exact same files will be present on several places simultaneously. ZFS checks the digital fingerprint of all the files on all drives in real time and in the event that the checksum of any file differs from what it should be, the file system swaps that file with a healthy version from another drive within the RAID. No other file system uses checksums, so it is easy for data to be silently damaged and the bad file to be replicated on all drives over time, but since that can never happen on a server running ZFS, you don't have to worry about the integrity of your data.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
In case you acquire one of our semi-dedicated hosting solutions, you will not need to be concerned about silent data corruption since we use ZFS - a high level file system which checks all of the files in real time. Every time you upload a file to your hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synced between several NVMe drives for redundancy, so if a drive fails, the other ones will take over. ZFS compares the checksum of all of the copies on the different drives and in case it detects a damaged copy, it replaces it with a healthy one from another drive. This is done right away, so there will be no risk for any part of your content at any time. In contrast, all the other file systems execute checks after a system malfunction, but since they do not use anything similar to the checksums that ZFS uses, they can't detect silently corrupted files, so a corrupted copy could be replicated on the remaining drives as well and you could lose crucial data. Since this is not the case with ZFS, we're able to guarantee the integrity of each and every file you upload no matter what.
