Data corruption is the damage of information caused by various hardware or software failures. Once a file gets damaged, it will no longer function accurately, so an application will not start or will give errors, a text file shall be partially or fully unreadable, an archive file will be impossible to open and unpack, etc. Silent data corruption is the process of information getting damaged without any acknowledgement by the system or an administrator, which makes it a significant problem for website hosting servers as failures are very likely to occur on larger hard drives where substantial volumes of information are kept. In case a drive is part of a RAID and the information on it is replicated on other drives for redundancy, it's more than likely that the bad file will be treated as a standard one and it will be duplicated on all the drives, making the harm permanent. Lots of the file systems which run on web servers these days often cannot locate corrupted files instantly or they need time-consuming system checks during which the server isn't working.
No Data Corruption & Data Integrity in Web Hosting
The integrity of the data which you upload to your new web hosting account shall be ensured by the ZFS file system that we take advantage of on our cloud platform. Most internet hosting service providers, like our firm, use multiple hard disk drives to keep content and because the drives work in a RAID, the exact same information is synchronized between the drives at all times. When a file on a drive is damaged for some reason, however, it's more than likely that it will be duplicated on the other drives because other file systems don't offer special checks for this. Unlike them, ZFS works with a digital fingerprint, or a checksum, for every single file. In the event that a file gets corrupted, its checksum won't match what ZFS has as a record for it, so the damaged copy shall be replaced with a good one from a different disk drive. Due to the fact that this happens in real time, there is no possibility for any of your files to ever get corrupted.
No Data Corruption & Data Integrity in Semi-dedicated Servers
In case you go for one of our semi-dedicated server packages, you won't need to be concerned about silent file corruption because we use ZFS - an advanced file system which 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. That file will be synchronized between several SSD drives for redundancy, so if a drive fails, the other ones will take control. ZFS compares the checksum of all copies on the different drives and in case it detects a damaged copy, it replaces it with a healthy one from a different drive. This is done instantly, so there will be no threat for any part of your content at any time. In comparison, alternative file systems perform checks only after a system malfunction, but since they do not use anything similar to the checksums which ZFS uses, they will not detect silently corrupted files, so a bad copy can be replicated on the rest of the disks as well and you could lose critical info. As this isn't the case with ZFS, we can guarantee the integrity of each file you upload no matter what.
