Data corruption is the damage of data due to various software or hardware fails. After a file gets corrupted, it will no longer work correctly, so an app will not start or will give errors, a text file will be partially or completely 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 website hosting servers as failures are more likely to happen on bigger hard drives where substantial volumes of info are located. If a drive is part of a RAID and the data on it is replicated on other drives for redundancy, it is more than likely that the bad file will be treated as an undamaged one and will be copied on all drives, making the harm permanent. A lot of the file systems that operate on web servers these days often are unable to detect corrupted files immediately or they need time-consuming system checks through which the server is not operational.

No Data Corruption & Data Integrity in Cloud Hosting

In case you host your Internet sites in a cloud hosting account from our company, you won't need to worry about any of your data ever getting corrupted. We can guarantee that as our cloud hosting platform employs the amazing ZFS file system. The aforementioned is the only file system that uses checksums, or unique digital fingerprints, for each file. All of the data that you upload will be stored in a RAID i.e. simultaneously on multiple SSDs. All of the file systems synchronize the files between the separate drives with this kind of a setup, but there is no real warranty that a file will not be corrupted. This may occur during the writing process on any drive and then a bad copy can be copied on all other drives. What makes the difference on our platform is the fact that ZFS examines the checksums of all files on all the drives immediately and in the event that a corrupted file is located, it's swapped with a good copy with the correct checksum from another drive. By doing this, your info will continue to be unharmed no matter what, even if a whole drive fails.
