Data corruption is the damage of info caused by various hardware or software fails. Once a file gets damaged, it will no longer work as it should, so an app will not start or will give errors, a text file can be partially or fully unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of info getting damaged without any identification by the system or an admin, that makes it a significant problem for hosting servers as fails are much more likely to occur on bigger hard drives where vast volumes of information are placed. In case a drive is part of a RAID and the info on it is copied on other drives for redundancy, it's likely that the bad file will be treated as an undamaged one and it'll be copied on all the drives, making the harm permanent. A lot of the file systems which operate on web servers nowadays often cannot detect corrupted files in real time or they need time-consuming system checks through which the server isn't working.
No Data Corruption & Data Integrity in Shared Hosting
In case you host your websites in a shared hosting
account with our company, you won't have to worry about any of your data ever getting corrupted. We can guarantee that since our cloud hosting platform employs the advanced ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for each and every file. All of the information that you upload will be stored in a RAID i.e. simultaneously on a large number of SSD drives. All file systems synchronize the files between the separate drives using this type of a setup, but there's no real guarantee that a file won't get corrupted. This can occur during the writing process on any drive and after that a bad copy can be copied on the rest of the drives. What is different on our platform is the fact that ZFS examines the checksums of all files on all drives in real time and in case a corrupted file is identified, it's replaced with a good copy with the correct checksum from another drive. This way, your information will stay intact no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Servers
You will not experience any kind of silent data corruption issues whatsoever should you get one of our semi-dedicated server
packages since the ZFS file system that we work with on our cloud hosting platform uses checksums in order to guarantee that all of your files are intact at all times. A checksum is a unique digital fingerprint that is assigned to each and every file stored on a server. Because we store all content on a number of drives at the same time, the same file has the same checksum on all of the drives and what ZFS does is that it compares the checksums between the different drives in real time. If it detects that a file is corrupted and its checksum is different from what it has to be, it replaces that file with a healthy copy without delay, avoiding any possibility of the bad copy to be synchronized on the rest of the hard drives. ZFS is the sole file system you can get that uses checksums, which makes it far superior to other file systems that are unable to detect silent data corruption and copy bad files across hard drives.
