Data corruption is the damage of data because of various hardware or software fails. Once a file is corrupted, it will no longer function properly, so an application will not start or will give errors, a text file could be partially or fully unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of information getting damaged without any acknowledgement by the system or an administrator, that makes it a serious problem for website hosting servers as failures are much more likely to occur on larger in size hard disks where substantial volumes of information are placed. If a drive is part of a RAID and the data on it is duplicated on other drives for redundancy, it's likely that the bad file will be treated as an ordinary one and it'll be duplicated on all the drives, making the damage permanent. Lots of the file systems that operate on web servers these days often are unable to discover corrupted files immediately or they need time-consuming system checks during which the server is not working.
No Data Corruption & Data Integrity in Shared Hosting
The integrity of the data which you upload to your new shared hosting
account shall be ensured by the ZFS file system that we make use of on our cloud platform. The vast majority of web hosting providers, like our firm, use multiple hard drives to keep content and considering that the drives work in a RAID, exactly the same information is synchronized between the drives at all times. If a file on a drive becomes damaged for some reason, yet, it's very likely that it will be copied on the other drives as alternative file systems do not have special checks for that. In contrast to them, ZFS applies a digital fingerprint, or a checksum, for every file. If 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 another drive. Since this happens immediately, there's no risk for any of your files to ever be corrupted.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
If you go for one of our semi-dedicated hosting
packages, you won't have to be concerned about silent data corruption as we use ZFS - a high level file system which checks all of 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. This file will be synced between a couple 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 in case it detects a damaged copy, it replaces it with a healthy one from another drive. This is done right away, so there will be no threat for any part of your content at any time. In comparison, other file systems carry out checks after a system malfunction, but since they don't use anything similar to the checksums which ZFS uses, they can't detect silently corrupted files, so a bad copy may be replicated on the remaining drives as well and you could lose precious data. Because this is not the case with ZFS, we can warrant the integrity of each and every file you upload no matter what.
