Data corruption is the damage of info due to various software or hardware failures. Once a file is corrupted, it will no longer function correctly, so an application will not start or shall give errors, a text file will be partially or fully unreadable, an archive file will be impossible to open and unpack, etc. Silent data corruption is the process of information getting damaged without any acknowledgement by the system or an administrator, which makes it a serious problem for website hosting servers as problems are more likely to happen on larger in size hard drives where substantial volumes of information are kept. If a drive is a part of a RAID and the information on it is duplicated on other drives for redundancy, it's very likely that the bad 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 these days often are not able to discover corrupted files instantly or they need time-consuming system checks during which the server isn't operational.
No Data Corruption & Data Integrity in Cloud Website Hosting
If you host your sites in a cloud website hosting account from our company, you do not need to worry about your data ever getting corrupted. We can guarantee that due to the fact that our cloud hosting platform uses the advanced ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for each and every file. Any kind of info that you upload will be stored in a RAID i.e. simultaneously on many SSD drives. Many file systems synchronize the files between the separate drives with such a setup, but there is no real warranty that a file won't get corrupted. This could happen during the writing process on each drive and then a corrupted copy may be copied on all other drives. What is different on our platform is the fact that ZFS examines the checksums of all files on all of the drives in real time and in the event that a corrupted file is discovered, it's substituted with a good copy with the correct checksum from another drive. That way, your info will continue to be undamaged 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 corrupted silently because the servers where your semi-dedicated hosting account will be created use a powerful file system known as ZFS. Its basic advantage over various other file systems is that it uses a unique checksum for every single file - a digital fingerprint that's checked in real time. As we store 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. In case there is a mismatch, the damaged copy is replaced with a healthy one from one of the other drives and considering that this happens right away, there's no chance that a damaged copy can remain on our servers or that it could be duplicated to the other drives in the RAID. None of the other file systems work with this type of checks and what is more, even during a file system check right after a sudden power failure, none of them can discover silently corrupted files. In contrast, ZFS does not crash after a power loss and the constant checksum monitoring makes a lenghty file system check unnecessary.
