Data corruption is the damage of info because of various hardware or software failures. After a file is corrupted, it will no longer work as it should, so an application will not start or shall give errors, a text file can be partially or entirely unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of data getting harmed without any identification by the system or an administrator, which makes it a serious problem for hosting servers as problems are very likely to happen on larger in size hard drives where considerable volumes of information are placed. If a drive is a part of a RAID and the information on it is replicated on other drives for redundancy, it is very likely that the damaged file will be treated as a standard one and it will be duplicated on all of the drives, making the harm permanent. A huge number of the file systems which operate on web servers nowadays often are not able to detect corrupted files immediately or they need time-consuming system checks during which the server is not operational.

No Data Corruption & Data Integrity in Hosting

We've tackled the issue of silent data corruption on all of our hosting servers by using the leading-edge Z file system, or ZFS. The latter is more advanced than other file systems because it is the only one out there that checks all of the files immediately by using a checksum - a digital identifier that 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 regularly analyzes the checksum of all files and in case any file is detected as corrupted, it's replaced instantly with a good copy from some other disk. As this happens in real time, there's no risk that a damaged file may remain or may be copied on the other NVMes. ZFS needs lots of physical memory in order to execute the real-time checks and the benefit of our cloud web hosting platform is that we employ multiple powerful servers working together. In case you host your sites with us, your data will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

You won't need to deal with any kind of silent data corruption issues whatsoever if you acquire one of our semi-dedicated hosting plans as the ZFS file system that we work with on our cloud hosting platform uses checksums to make sure that all the files are intact all the time. A checksum is a unique digital fingerprint that 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 uses the same checksum on all of the drives and what ZFS does is that it compares the checksums between the different drives right away. In the event that 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 without delay, avoiding any probability of the corrupted copy to be synchronized on the remaining hard disks. ZFS is the sole file system on the market which uses checksums, which makes it much more reliable than other file systems that cannot identify silent data corruption and copy bad files across hard drives.
