Data corruption is the damage of info because of various software or hardware fails. The moment a file gets damaged, it will no longer function as it should, so an app will not start or shall give errors, a text file can be partially or fully unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of info getting harmed without any identification by the system or an admin, which makes it a serious problem for hosting servers as failures are very likely to occur on bigger hard disk drives where vast volumes of information are stored. If a drive is part of a RAID and the info on it is copied on other drives for redundancy, it is very likely that the bad file will be treated as an ordinary one and it will be copied on all the drives, making the harm permanent. A lot of the file systems that run on web servers these days often cannot discover corrupted files in real time or they need time-consuming system checks during which the server isn't functioning.
No Data Corruption & Data Integrity in Shared Hosting
In case you host your sites in a shared hosting account with our firm, you will not need to worry about your data ever getting corrupted. We can guarantee that due to the fact that our cloud hosting platform employs the cutting-edge ZFS file system. The latter is the only file system that uses checksums, or unique digital fingerprints, for every single file. Any kind of information that you upload will be saved in a RAID i.e. simultaneously on many different SSDs. Many file systems synchronize the files between the different drives with this kind of a setup, but there is no real warranty that a file will not get corrupted. This can happen during the writing process on any drive and after that a bad copy may be copied on all other drives. What is different on our platform is the fact that ZFS analyzes the checksums of all files on all the drives immediately and when a corrupted file is discovered, it is substituted with a good copy with the correct checksum from another drive. By doing this, your data will continue to be unharmed no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Servers
We have avoided any probability of files getting corrupted silently since the servers where your semi-dedicated server account will be created use a powerful file system known as ZFS. Its key advantage over alternative file systems is that it uses a unique checksum for each and every file - a digital fingerprint that is checked in real time. Since we keep 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 saved. In the event that there's a mismatch, the damaged copy is replaced with a good one from one of the other drives and considering that it happens right away, there's no chance that a corrupted copy can remain on our web hosting servers or that it can be copied to the other hard drives in the RAID. None of the other file systems work with this kind of checks and what's more, even during a file system check after a sudden power loss, none of them will detect silently corrupted files. In comparison, ZFS will not crash after a blackout and the continual checksum monitoring makes a lenghty file system check unneeded.
