Data corruption is the damage of information caused by various software or hardware problems. After a file gets damaged, it will no longer work accurately, so an app will not start or will give errors, a text file shall be partially or entirely unreadable, an archive file 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 serious problem for web hosting servers as problems are much more likely to occur on larger hard disks where substantial volumes of info are kept. In case a drive is part of a RAID and the info on it is replicated on other drives for redundancy, it's likely that the bad file will be treated as a healthy one and it'll be duplicated on all the drives, making the damage permanent. Lots of the file systems that operate on web servers nowadays often are unable to find corrupted files instantly or they need time-consuming system checks through which the server isn't operational.
No Data Corruption & Data Integrity in Cloud Hosting
The integrity of the data that you upload to your new cloud hosting
account shall be ensured by the ZFS file system which we take advantage of on our cloud platform. The vast majority of internet hosting suppliers, including our firm, use multiple HDDs to store content and because the drives work in a RAID, the exact same info is synchronized between the drives at all times. If a file on a drive becomes damaged for reasons unknown, however, it is very likely that it will be copied on the other drives since alternative file systems don't have special checks for that. Unlike them, ZFS works with a digital fingerprint, or a checksum, for every file. In the event that a file gets corrupted, its checksum won't match what ZFS has as a record for it, therefore the bad copy shall be replaced with a good one from a different hard disk. Since this happens in real time, there is no possibility for any of your files to ever be corrupted.
No Data Corruption & Data Integrity in Semi-dedicated Servers
In case you get one of our semi-dedicated server
solutions, you won't have to be concerned about silent data corruption because we use ZFS - an advanced file system which monitors all of the files in real time. Each time you upload a file to your hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synced between a number of SSD drives for redundancy, so if a drive fails, the other ones will take control. 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 a different drive. This happens instantly, so there will be no threat for any part of your content at any moment. In comparison, all of the other file systems perform checks only after a system malfunction, but since they don't use anything similar to the checksums that ZFS uses, they won't detect silently corrupted files, so a corrupted copy could be replicated on the rest of the disks as well and you can lose precious info. As this isn't the case with ZFS, we are able to guarantee the integrity of every single file you upload no matter what.
