No Data Corruption & Data Integrity

Find out what No Data Corruption & Data Integrity is and how it could be beneficial for the files in your hosting account.

Data corruption is the damage of information because of various software or hardware failures. Once a file gets corrupted, it will no longer work properly, so an app will not start or shall give errors, a text file will be partially or entirely unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of data getting damaged without any identification by the system or an administrator, that makes it a significant problem for website hosting servers as fails are more likely to occur on bigger hard disks where large volumes of information are located. When a drive is part of a RAID and the information on it is duplicated on other drives for redundancy, it is likely that the damaged file will be treated as a standard one and it'll be copied on all the drives, making the harm permanent. A huge number of the file systems which operate on web servers these days often are unable to discover corrupted files instantly or they need time-consuming system checks through which the server is not functioning.

: No Data Corruption & Data Integrity in Semi-dedicated Hosting

In case you go for one of our semi-dedicated hosting solutions, you will not need to be concerned about silent file corruption since we use ZFS - a high level file system that checks all of the files in real time. Each time you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synced between several NVMe drives for redundancy, so if a drive fails, the other ones will take control. ZFS compares the checksum of all copies on the different drives and when it detects a damaged copy, it replaces it with a healthy one from another drive. This happens instantly, so there will be no danger for any part of your content at any time. In contrast, alternative file systems perform checks only after a system breakdown, but since they do not use anything similar to the checksums that ZFS uses, they won't detect silently corrupted files, so a corrupted copy may be replicated on the rest of the drives as well and you may lose crucial info. As this is not the case with ZFS, we are able to guarantee the integrity of every single file you upload no matter what.
