Data corruption is the damage of information due to various hardware or software failures. The moment a file is damaged, it will no longer work as it should, so an app will not start or shall give errors, a text file will be partially or entirely unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of information getting harmed without any acknowledgement by the system or an admin, which makes it a significant problem for website hosting servers as problems are much more likely to happen on bigger hard disks where large volumes of info are kept. In case a drive is part of a RAID and the data on it is copied on other drives for redundancy, it is more than likely that the bad file will be treated as an ordinary one and it'll be copied on all the drives, making the harm permanent. A lot of the file systems which operate on web servers nowadays often are not able to discover corrupted files in real time or they need time-consuming system checks through which the server is not working.
No Data Corruption & Data Integrity in Shared Hosting
We warrant the integrity of the info uploaded in each and every shared hosting account which is generated on our cloud platform because we employ the advanced ZFS file system. The aforementioned is the only one which was designed to prevent silent data corruption via a unique checksum for every single file. We'll store your data on a number of NVMe drives which function in a RAID, so the very same files will exist on several places at once. ZFS checks the digital fingerprint of all of the files on all of 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 a healthy version from some other drive within the RAID. No other file system uses checksums, so it's possible for data to get silently corrupted and the bad file to be reproduced on all drives with time, but since this 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 Servers
In case you obtain one of our semi-dedicated server solutions, you won't have to be concerned about silent file corruption as we use ZFS - an advanced file system which monitors all files in real time. Each time 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 synced between several NVMe drives for redundancy, so if a drive fails, the other ones will take over. ZFS compares the checksum of all copies on the different drives and when it detects a corrupted copy, it replaces it with a healthy one from another drive. This is done instantly, so there will be no danger for any part of your content at any time. In comparison, all the other file systems perform checks only after a system breakdown, but since they don't use anything similar to the checksums that ZFS uses, they cannot detect silently corrupted files, so a corrupted copy can be replicated on the other disks as well and you can lose critical info. Since this is not the case with ZFS, we warrant the integrity of every single file you upload no matter what.
