Data corruption is the damage of information due to various software or hardware fails. The moment a file is damaged, it will no longer work accurately, so an application will not start or shall give errors, a text file shall be partially or completely unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of info getting damaged without any acknowledgement by the system or an administrator, which makes it a serious problem for website hosting servers as problems are very likely to happen on larger in size hard drives where substantial volumes of information are placed. When a drive is part of a RAID and the information on it is replicated on other drives for redundancy, it's more than likely that the damaged file will be treated as a good one and will be copied on all of the drives, making the harm permanent. A lot of the file systems which operate on web servers nowadays often are unable to find corrupted files in real time or they need time-consuming system checks through which the server isn't operational.

No Data Corruption & Data Integrity in Cloud Hosting

We have resolved the problem of silent data corruption on our cloud hosting servers by using the cutting-edge Z file system, or ZFS. The latter is more advanced than other file systems as it is the only one on the market that checks all files instantly by employing a checksum - a digital identifier which is unique for each and every file. When you upload content to your account, it'll be stored on several NVMe drives and constantly synchronized between them for redundancy. ZFS constantly analyzes the checksum of all files and if any file is detected as corrupted, it's replaced promptly with a good copy from some other disk. As this happens in real time, there is no risk that a bad file may remain or may be duplicated on the other NVMes. ZFS requires plenty of physical memory to execute the real-time checks and the advantage of our cloud website hosting platform is that we employ multiple powerful servers working together. In case you host your websites with us, your data will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

You won't have to deal with any silent data corruption issues whatsoever in case you buy one of our semi-dedicated hosting packages due to the fact that the ZFS file system that we work with on our cloud hosting platform uses checksums in order to make sure that all of your files are undamaged all of the time. A checksum is a unique digital fingerprint which is allotted to each and every file stored on a server. Due to the fact that we store all content on multiple 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. 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 corrupted copy to be synchronized on the remaining drives. ZFS is the sole file system you can get that uses checksums, which makes it much more reliable than other file systems which are unable to detect silent data corruption and duplicate bad files across drives.
