Data corruption is the damage of data because of various software or hardware fails. The moment a file is corrupted, it will no longer work accurately, so an application will not start or shall give errors, a text file can be partially or entirely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of data getting harmed without any acknowledgement by the system or an administrator, that makes it a serious problem for website hosting servers as problems are much more likely to occur on larger in size hard disks where significant volumes of information are placed. In case a drive is a part of a RAID and the data on it is replicated on other drives for redundancy, it's likely that the damaged file will be treated as an undamaged one and it'll be duplicated on all drives, making the harm permanent. Lots of the file systems that operate on web servers today often are unable to discover corrupted files in real time or they need time-consuming system checks during which the server is not operational.
No Data Corruption & Data Integrity in Shared Hosting
We guarantee the integrity of the information uploaded in each and every shared hosting account which is generated 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 through a unique checksum for every single file. We shall store your info on multiple SSD drives which operate in a RAID, so the same files will be present on several places at the same time. ZFS checks the digital fingerprint of all of the files on all drives in real time and if the checksum of any file is different from what it needs to be, the file system swaps that file with an undamaged copy from another drive inside the RAID. There's no other file system that uses checksums, so it's easy for data to be silently damaged and the bad file to be reproduced on all drives with time, but since this can never happen on a server running ZFS, you will not have to worry about the integrity of your information.
