Data corruption is the damage of information due to various hardware or software problems. After a file is corrupted, it will no longer work as it should, so an application will not start or shall give errors, a text file shall be partially or completely unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of info getting damaged without any identification by the system or an administrator, that makes it a significant problem for hosting servers as problems are much more likely to happen on larger hard disks where large volumes of information are located. In case a drive is a part of a RAID and the information 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 duplicated on all drives, making the damage permanent. A huge number of the file systems that operate on web servers these days often are unable to detect corrupted files instantly 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 Internet sites in a shared hosting
account with our firm, you will not need to worry about your data ever getting damaged. We can guarantee that since our cloud hosting platform works with the state-of-the-art ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for every single file. All of the information that you upload will be saved in a RAID i.e. simultaneously on many different SSDs. All of the file systems synchronize the files between the different drives using such a setup, but there is no real guarantee that a file will not be corrupted. This may happen throughout the writing process on each drive and afterwards a bad copy may 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 right away and if a corrupted file is discovered, it's replaced with a good copy with the correct checksum from some other drive. 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
You will not experience any silent data corruption issues whatsoever if you get one of our semi-dedicated server
packages as the ZFS file system that we use on our cloud hosting platform uses checksums to ensure that all files are undamaged all the time. A checksum is a unique digital fingerprint that is given to each and every file stored on a server. Since we store all content on a number of drives simultaneously, the same file has the same checksum on all drives and what ZFS does is that it compares the checksums between the different drives right away. In the event that 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 right away, avoiding any chance of the corrupted copy to be synchronized on the rest of the hard drives. ZFS is the only file system you can get which uses checksums, which makes it far superior to other file systems that cannot identify silent data corruption and duplicate bad files across drives.
