Data corruption is the damage of data because of various software or hardware fails. When a file gets damaged, it will no longer work properly, so an application will not start or will give errors, a text file can be partially or entirely unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of information getting harmed without any identification by the system or an admin, which makes it a significant problem for web hosting servers as fails are very likely to happen on bigger hard disks where vast volumes of info are kept. When a drive is part of a RAID and the data on it is replicated on other drives for redundancy, it is very likely that the bad file will be treated as an undamaged one and will be duplicated on all the drives, making the damage permanent. Lots of the file systems that run on web servers nowadays often cannot recognize corrupted files instantly or they need time-consuming system checks through 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 from our firm, you do not need to worry about any of your data ever getting corrupted. We can guarantee that because our cloud hosting platform employs the revolutionary ZFS file system. The aforementioned is the only file system which works with checksums, or unique digital fingerprints, for each and every file. All data that you upload will be stored in a RAID i.e. simultaneously on many SSD drives. All the file systems synchronize the files between the different drives with this type of a setup, but there's no real guarantee that a file won't get corrupted. This may occur during the writing process on any drive and afterwards a corrupted copy may 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 immediately and in the event that a corrupted file is discovered, it's replaced with a good copy with the correct checksum from some other drive. This way, your data will remain undamaged no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

In case you get one of our semi-dedicated hosting packages, you will not have to be concerned about silent data corruption because we use ZFS - a high level file system that monitors all the files in real time. Each time you upload a file to your hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synced between a number of 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 damaged copy, it replaces it with a healthy one from another drive. This happens in real time, so there will be no danger for any part of your content at any time. In contrast, all of the other file systems perform checks only after a system failure, but since they do not use anything similar to the checksums which ZFS uses, they cannot detect silently corrupted files, so a corrupted copy can be replicated on the rest of the drives as well and you can lose crucial info. Since this isn't the case with ZFS, we are able to guarantee the integrity of every single file you upload no matter what.
