Data corruption is the damage of information due to various software or hardware problems. Once a file gets corrupted, it will no longer function correctly, so an application will not start or shall give errors, a text file shall be partially or fully unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of data getting damaged without any identification by the system or an admin, which makes it a significant problem for web hosting servers as fails are much more likely to occur on larger in size hard disks where substantial volumes of information are stored. In case a drive is part of a RAID and the information on it is duplicated on other drives for redundancy, it's more than likely that the bad file will be treated as an undamaged one and it will be duplicated on all the drives, making the harm permanent. A lot of the file systems which run on web servers these days often are unable to discover corrupted files right away or they need time-consuming system checks through which the server is not working.

No Data Corruption & Data Integrity in Cloud Hosting

We warrant the integrity of the data uploaded in any cloud hosting account that is made on our cloud platform as we employ the advanced ZFS file system. The latter is the only one which was designed to avert silent data corruption via a unique checksum for each file. We will store your info on a large number of NVMe drives that function in a RAID, so the exact same files will exist on several places at once. ZFS checks the digital fingerprint of all files on all the drives in real time and in case the checksum of any file differs from what it has to be, the file system swaps that file with a healthy copy from some other drive within the RAID. No other file system uses checksums, so it's possible for data to be silently corrupted and the bad file to be duplicated on all drives with time, but since this can never happen on a server using ZFS, you don't have to worry about the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

In case you buy one of our semi-dedicated hosting packages, you will not need to worry about silent data corruption because we use ZFS - an advanced file system that checks all the files in real time. Each time you upload a file to your web hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synced between a couple of NVMe drives for redundancy, so if a drive fails, the other ones will take over. ZFS compares the checksum of all the copies on the different drives and in case it detects a corrupted copy, it replaces it with a healthy one from another drive. This happens instantly, so there will be no risk for any part of your content at any moment. In comparison, all the other file systems execute checks only after a system failure, but since they don't use anything similar to the checksums that ZFS uses, they will not detect silently corrupted files, so a corrupted copy may be replicated on the rest of the drives as well and you can lose crucial data. As this is not the case with ZFS, we are able to guarantee the integrity of each and every file you upload no matter what.
