Data corruption is the damage of data caused by various software or hardware failures. Once a file gets damaged, it will no longer function properly, so an app will not start or will give errors, a text file will be partially or fully unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of information getting damaged without any identification by the system or an administrator, that makes it a serious problem for web hosting servers as fails are much more likely to happen on larger hard disk drives where vast volumes of information are stored. If a drive is a part of a RAID and the data on it is duplicated on other drives for redundancy, it is likely that the bad file will be treated as a healthy one and will be duplicated on all of the drives, making the harm permanent. A huge number of the file systems that operate on web servers today often cannot detect corrupted files immediately or they need time-consuming system checks during which the server isn't working.

No Data Corruption & Data Integrity in Cloud Web Hosting

In case you host your sites in a cloud web hosting account from our firm, you won't have to worry about any of your data ever getting damaged. We can ensure that since our cloud hosting platform works with the advanced ZFS file system. The latter is the only file system that uses checksums, or unique digital fingerprints, for each and every file. Any kind of data that you upload will be kept in a RAID i.e. simultaneously on many SSD drives. A lot of file systems synchronize the files between the separate drives using this type of a setup, but there is no real guarantee that a file will not get corrupted. This may occur at the time of the writing process on any drive and after that a corrupted copy may be copied on all other drives. What is different on our platform is the fact that ZFS compares the checksums of all files on all the drives right away and in the event that a corrupted file is discovered, it's replaced with a good copy with the correct checksum from another drive. In this way, your data will continue to be intact no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

In case you obtain one of our semi-dedicated hosting solutions, you won't need to worry about silent file corruption as 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 hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synced between several SSD drives for redundancy, so if one drive fails, the other ones will take control. ZFS compares the checksum of all copies on the different drives and when it detects a corrupted copy, it replaces it with a healthy one from another drive. This happens right away, so there will be no risk for any part of your content at any moment. In comparison, all the other file systems perform checks after a system failure, but since they do not use anything similar to the checksums that ZFS uses, they won't detect silently corrupted files, so a bad copy could be replicated on the other drives as well and you may lose critical information. As this isn't the case with ZFS, we can warrant the integrity of each file you upload no matter what.
