Data corruption is the damage of data because of various software or hardware failures. The moment a file gets corrupted, it will no longer function properly, so an application will not start or will give errors, a text file shall be partially or fully unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of information getting damaged without any acknowledgement by the system or an admin, that makes it a significant problem for web hosting servers as problems are much more likely to occur on larger in size hard disks where vast volumes of information are kept. If a drive is part of a RAID and the info on it is duplicated on other drives for redundancy, it is likely that the bad file will be treated as a good one and it will be duplicated on all the drives, making the damage permanent. Lots of the file systems which operate on web servers nowadays often cannot discover corrupted files instantly or they need time-consuming system checks during which the server isn't functioning.

No Data Corruption & Data Integrity in Shared Hosting

We guarantee the integrity of the info uploaded in each and every shared hosting account which is made on our cloud platform because we use the advanced ZFS file system. The latter is the only one that was designed to avoid silent data corruption using a unique checksum for each and every file. We'll store your data on multiple SSD drives that function in a RAID, so the exact same files will exist on several places simultaneously. ZFS checks the digital fingerprint of all the files on all the drives in real time and in the event that the checksum of any file is different from what it has to be, the file system replaces that file with an undamaged version from a different drive within the RAID. There's no other file system that uses checksums, so it is easy for data to become silently corrupted and the bad file to be duplicated on all drives over time, but since that can never happen on a server running ZFS, you will not have to concern yourself with the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Servers

If you obtain one of our semi-dedicated server solutions, you won't have to be concerned about silent data corruption as we use ZFS - an advanced file system that checks all of the files in real time. Whenever you upload a file to your website hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synchronized between a number of SSD drives for redundancy, so if one drive fails, the other ones will take over. ZFS compares the checksum of all of the copies on the different drives and if it detects a damaged copy, it replaces it with a healthy one from a different drive. This happens immediately, so there will be no risk for any part of your content at any time. In contrast, alternative file systems execute checks only after a system failure, but since they do not use anything similar to the checksums which ZFS uses, they cannot detect silently corrupted files, so a bad copy may be replicated on the remaining drives as well and you can lose crucial info. Because this is not the case with ZFS, we are able to warrant the integrity of every single file you upload no matter what.
