Data corruption is the damage of info caused by various software or hardware failures. After a file is damaged, it will no longer work correctly, so an application will not start or will give errors, a text file could be partially or completely unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of information getting harmed without any acknowledgement 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 in size hard disks where substantial volumes of info are kept. In case a drive is part of a RAID and the data 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 will be copied on all the drives, making the damage permanent. A huge number of the file systems that run on web servers today often cannot locate corrupted files right away or they need time-consuming system checks during which the server is not operational.
No Data Corruption & Data Integrity in Cloud Hosting
We warrant the integrity of the information uploaded in any cloud hosting account that is made on our cloud platform because we work with the advanced ZFS file system. The aforementioned is the only one that was designed to prevent silent data corruption thanks to a unique checksum for each and every file. We will store your data on a large number of SSD drives that work in a RAID, so the same files will be present on several places at once. ZFS checks the digital fingerprint of all files on all of the drives in real time and if the checksum of any file differs from what it needs to be, the file system replaces that file with an undamaged version from another drive within the RAID. No other file system uses checksums, so it's easy for data to be silently corrupted and the bad file to be replicated on all drives over time, but since this can never happen on a server using ZFS, you won't have to concern yourself with the integrity of your data.
