Data corruption is the damage of information because of various hardware or software problems. Once a file is damaged, it will no longer work properly, so an app will not start or will give errors, a text file could be partially or entirely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of info getting damaged without any identification by the system or an admin, which makes it a serious problem for website hosting servers as problems are more likely to happen on larger hard disks where large volumes of information are stored. In case a drive is a part of a RAID and the data on it is copied on other drives for redundancy, it's more than likely that the bad file will be treated as a standard one and it will be duplicated on all the drives, making the harm permanent. A huge number of the file systems that run on web servers these days often are not able to recognize corrupted files right away 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 sites in a website hosting
account with our firm, you don't need to worry about any of your data ever getting corrupted. We can guarantee that because our cloud hosting platform works with the advanced ZFS file system. The aforementioned is the only file system that uses checksums, or unique digital fingerprints, for each and every file. All of the information that you upload will be kept in a RAID i.e. simultaneously on a number of SSD drives. Many file systems synchronize the files between the separate drives using this kind of a setup, but there is no real guarantee that a file won't get corrupted. This could occur throughout the writing process on any drive and afterwards a corrupted copy may be copied on the rest of the drives. What is different on our platform is the fact that ZFS compares the checksums of all files on all of the drives right away and if a corrupted file is identified, it's swapped with a good copy with the correct checksum from another drive. In this way, your info will remain intact no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Servers
We've avoided any chance of files getting corrupted silently since the servers where your semi-dedicated server
account will be created employ a powerful file system called ZFS. Its basic advantage over other file systems is that it uses a unique checksum for each and every file - a digital fingerprint that's 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 remaining drives and the one it has saved. In case there's a mismatch, the corrupted copy is replaced with a healthy one from one of the other drives and because it happens in real time, there is no chance that a corrupted copy could remain on our website hosting servers or that it can be duplicated to the other drives in the RAID. None of the other file systems work with this type of checks and in addition, even during a file system check following a sudden power failure, none of them can find silently corrupted files. In contrast, ZFS won't crash after an electrical power failure and the constant checksum monitoring makes a time-consuming file system check unnecessary.
