Data corruption is the damage of data caused by various hardware or software problems. The moment a file gets corrupted, it will no longer work properly, so an app will not start or shall give errors, a text file could be partially or completely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of data getting damaged without any acknowledgement by the system or an administrator, which makes it a serious problem for web hosting servers as fails are more likely to happen on larger hard disk drives where vast volumes of info are located. If a drive is a part of a RAID and the data on it is copied on other drives for redundancy, it's more than likely that the bad file will be treated as an ordinary one and it'll be copied on all drives, making the damage permanent. A huge number of the file systems which operate on web servers these days often are unable to identify corrupted files in real time or they need time-consuming system checks through which the server is not operational.
No Data Corruption & Data Integrity in Shared Hosting
We guarantee the integrity of the information uploaded in each shared hosting
account that is generated on our cloud platform since we work with the advanced ZFS file system. The aforementioned is the only one that was designed to avoid silent data corruption through a unique checksum for every single file. We will store your info on a number of SSD drives which function in a RAID, so the same files will exist on several places concurrently. ZFS checks the digital fingerprint of all files on all the drives in real time and in case the checksum of any file differs from what it should be, the file system swaps that file with a healthy copy from a different drive inside the RAID. There's no other file system that uses checksums, so it is possible for data to be silently corrupted and the bad file to be reproduced on all drives over time, but since this can never happen on a server running ZFS, you do not have to worry about the integrity of your info.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You will not encounter any silent data corruption issues whatsoever in case you get one of our semi-dedicated hosting
solutions as the ZFS file system that we employ on our cloud hosting platform uses checksums to make sure that all the files are undamaged all the time. A checksum is a unique digital fingerprint which is allotted to each and every file saved on a server. As we store all content on multiple drives simultaneously, the same file uses the same checksum on all the drives and what ZFS does is that it compares the checksums between the different drives right away. When 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 possibility of the damaged copy to be synchronized on the remaining hard disks. ZFS is the sole file system on the market which uses checksums, which makes it far superior to other file systems that are unable to identify silent data corruption and copy bad files across hard drives.
