Data corruption is the damage of information due to various hardware or software fails. After a file gets corrupted, it will no longer work as it should, so an app will not start or shall give errors, a text file could be partially or fully unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of data getting damaged without any identification by the system or an admin, which makes it a serious problem for hosting servers as failures are more likely to occur on larger hard drives where vast volumes of information are stored. In case a drive is a 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 an undamaged one and will be duplicated on all the drives, making the damage permanent. Lots of the file systems which run on web servers nowadays often cannot locate corrupted files immediately or they need time-consuming system checks through which the server is not functioning.

No Data Corruption & Data Integrity in Shared Web Hosting

We have dealt with the problem of silent data corruption on all of our shared web hosting servers by using the amazing Z file system, or ZFS. The latter is more advanced than other file systems because it is the only one in existence which checks all the files instantly by employing a checksum - a digital identifier that is unique for each and every file. When you upload content to your account, it will be stored on several NVMe drives and frequently synchronized between them for redundancy. ZFS regularly analyzes the checksum of all files and in case any file is detected as corrupted, it is replaced quickly with a good copy from another disk. As this happens in real time, there is no risk that a corrupted file may remain or may be copied on the remaining NVMes. ZFS requires lots of physical memory to carry out the real-time checks and the benefit of our cloud web hosting platform is that we work with multiple powerful servers working together. If you host your Internet sites with us, your information will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be shielded from silent data corruption since all our storage servers employ the advanced ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, to ensure the integrity of every single file. When you upload content to your account, it'll be stored on several redundant drives employed in a RAID i.e. the files will be the same on all disks. All the copies of a particular file will feature the same checksum on all hard disks and ZFS will compare the checksums of the duplicates right away, and if it finds a mismatch, which would indicate that one of the copies is damaged, it will swap that file with a good copy from one of the other disks. Even if there's an unexpected power loss, the data on the servers won't become corrupted and there won't be any need for a time-consuming system check which other file systems perform following some failure, prolonging the time needed for the server to return online. ZFS is the file system which can really protect your content from silent data corruption.
