Data corruption is the damage of data caused by various software or hardware failures. Once a file is damaged, it will no longer function accurately, so an application will not start or shall give errors, a text file shall be partially or completely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of info getting harmed without any acknowledgement by the system or an admin, that makes it a significant problem for hosting servers as failures are more likely to occur on bigger hard drives where substantial volumes of information are placed. If a drive is a part of a RAID and the info on it is replicated on other drives for redundancy, it is likely that the bad file will be treated as a healthy one and it'll be copied on all of the drives, making the damage permanent. A huge number of the file systems which run on web servers these days often are not able to discover corrupted files right away or they need time-consuming system checks during which the server isn't functioning.
No Data Corruption & Data Integrity in Cloud Hosting
We guarantee the integrity of the data uploaded in each and every cloud hosting
account that is made on our cloud platform as we use the advanced ZFS file system. The latter is the only one which was designed to prevent silent data corruption thanks to a unique checksum for every single file. We will store your information on a large number of SSD drives that function in a RAID, so exactly the same files will be accessible on several places simultaneously. 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 replaces that file with a healthy version from another drive within the RAID. There's no other file system which uses checksums, so it is possible for data to get silently damaged and the bad file to be reproduced on all drives over time, but since this can never happen on a server using ZFS, you will not have to worry about the integrity of your info.
No Data Corruption & Data Integrity in Semi-dedicated Servers
In case you obtain one of our semi-dedicated server
packages, you won't have to worry about silent data corruption because we use ZFS - a high level file system that checks all of the files in real time. Every time you upload a file to your website hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synced between several SSD drives for redundancy, so if one drive fails, the other ones will take over. ZFS compares the checksum of all the copies on the different drives and if it detects a damaged 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 time. By comparison, alternative file systems perform 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 rest of the disks as well and you may lose important information. Since this isn't the case with ZFS, we guarantee the integrity of each and every file you upload no matter what.
