Data corruption is the damage of info caused by various hardware or software failures. When a file gets damaged, it will no longer work properly, so an application will not start or will give errors, a text file could be partially or completely unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of information getting harmed without any acknowledgement by the system or an admin, that makes it a serious problem for website hosting servers as problems are more likely to occur on bigger hard disk drives where considerable volumes of information are placed. When a drive is part of a RAID and the info on it is copied on other drives for redundancy, it's more than likely that the bad file will be treated as a good one and it'll be duplicated on all of the drives, making the harm permanent. A huge number of the file systems that run on web servers these days often cannot identify corrupted files in real time or they need time-consuming system checks during which the server is not working.

No Data Corruption & Data Integrity in Cloud Web Hosting

In case you host your sites in a cloud web hosting account with our firm, you don't need to worry about any of your data ever getting damaged. We can ensure that as our cloud hosting platform works with the amazing ZFS file system. The aforementioned is the only file system that works with checksums, or unique digital fingerprints, for every single file. Any information that you upload will be stored in a RAID i.e. simultaneously on a number of SSD drives. All the file systems synchronize the files between the different drives with this type of a setup, but there is no real warranty that a file won't be corrupted. This may happen throughout the writing process on each drive and afterwards a bad 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 immediately and in the event that a corrupted file is found, it's replaced with a good copy with the correct checksum from some other drive. In this way, your info will continue to be intact no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We have avoided any risk of files getting damaged silently since the servers where your semi-dedicated hosting account will be created employ a powerful file system known as ZFS. Its main advantage over other file systems is that it uses a unique checksum for each and every file - a digital fingerprint that's checked in real time. As we save all content on numerous SSD drives, ZFS checks if the fingerprint of a file on one drive matches the one on the other drives and the one it has stored. In case there's a mismatch, the corrupted copy is replaced with a good one from one of the other drives and because this happens in real time, there is no chance that a damaged copy could remain on our web hosting servers or that it can be copied to the other hard disks in the RAID. None of the other file systems work with this type of checks and furthermore, even during a file system check following an unexpected electrical power failure, none of them will detect silently corrupted files. In contrast, ZFS won't crash after a power failure and the regular checksum monitoring makes a time-consuming file system check obsolete.
