Data corruption is the damage of info because of various software or hardware failures. After a file gets corrupted, it will no longer function correctly, so an application will not start or will give errors, a text file will be partially or fully unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of information getting harmed without any acknowledgement by the system or an administrator, which makes it a significant problem for website hosting servers as problems are much more likely to happen on larger hard disk drives where significant volumes of info are stored. In case a drive is part of a RAID and the information on it is replicated on other drives for redundancy, it's likely that the bad file will be treated as an ordinary one and will be duplicated on all the drives, making the damage permanent. A lot of the file systems which operate on web servers nowadays often cannot recognize corrupted files immediately 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 Internet sites in a cloud web hosting account with our company, you don't have to worry about any of your data ever getting corrupted. We can guarantee that as our cloud hosting platform works with the leading-edge ZFS file system. The aforementioned is the only file system that uses checksums, or unique digital fingerprints, for every single file. All of the info that you upload will be stored in a RAID i.e. simultaneously on many NVMes. A lot of file systems synchronize the files between the different drives with such a setup, but there's no real guarantee that a file won't be corrupted. This can occur during the writing process on each drive and after that a corrupted copy can be copied on the rest of the drives. What makes the difference on our platform is the fact that ZFS compares the checksums of all files on all the drives right away and in case a corrupted file is identified, it's substituted with a good copy with the correct checksum from some other drive. That way, your info will continue to be undamaged no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Servers
We have avoided any possibility of files getting damaged silently due to the fact that the servers where your semi-dedicated server account will be created employ a powerful file system called ZFS. Its basic advantage over various other file systems is that it uses a unique checksum for each file - a digital fingerprint which is checked in real time. As we store all content on a number of NVMe drives, ZFS checks if the fingerprint of a file on one drive corresponds to the one on the other drives and the one it has saved. In case there's a mismatch, the damaged copy is replaced with a healthy one from one of the other drives and because this happens in real time, there's no chance that a corrupted copy could remain on our hosting servers or that it can be duplicated to the other hard disks in the RAID. None of the other file systems employ this kind of checks and in addition, even during a file system check following an unexpected power loss, none of them can identify silently corrupted files. In contrast, ZFS doesn't crash after a power failure and the regular checksum monitoring makes a time-consuming file system check unneeded.
