Data corruption is the damage of information due to various software or hardware fails. The moment a file is corrupted, it will no longer function properly, so an application will not start or shall give errors, a text file could be partially or fully unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of info getting damaged without any acknowledgement by the system or an admin, that makes it a significant problem for hosting servers as fails are much more likely to happen on larger in size hard disk drives where considerable volumes of information are stored. If a drive is a part of a RAID and the info on it is copied on other drives for redundancy, it's likely that the damaged file will be treated as an undamaged one and it'll be copied on all drives, making the harm permanent. A lot of the file systems which run on web servers today often cannot recognize corrupted files immediately or they need time-consuming system checks during which the server is not operational.

No Data Corruption & Data Integrity in Website Hosting

In case you host your websites in a website hosting account with our firm, you don't have to worry about your data ever getting damaged. We can guarantee that since our cloud hosting platform uses the state-of-the-art ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for each file. All data that you upload will be stored in a RAID i.e. simultaneously on a large number of SSDs. A lot of file systems synchronize the files between the different drives with this type of a setup, but there's no real warranty that a file won't get corrupted. This could happen at the time of the writing process on any drive and then a bad copy can be copied on the other drives. What makes the difference on our platform is that ZFS examines the checksums of all files on all the drives instantly and when a corrupted file is identified, it's substituted with a good copy with the correct checksum from another drive. In this way, your data will remain intact no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We've avoided any probability of files getting corrupted silently since the servers where your semi-dedicated hosting account will be created take advantage of a powerful file system called ZFS. Its key advantage over alternative file systems is that it uses a unique checksum for every single file - a digital fingerprint that is checked in real time. Since we keep all content on multiple SSD drives, ZFS checks whether the fingerprint of a file on one drive corresponds to the one on the rest of the drives and the one it has saved. If there is a mismatch, the bad copy is replaced with a good one from one of the other drives and considering that this happens right away, there's no chance that a corrupted copy can remain on our servers or that it can be duplicated to the other hard disks in the RAID. None of the other file systems work with such checks and in addition, even during a file system check after a sudden electrical power failure, none of them will discover silently corrupted files. In contrast, ZFS won't crash after a power failure and the constant checksum monitoring makes a lenghty file system check obsolete.
