Data corruption is the damage of info caused by various hardware or software failures. When a file is damaged, it will no longer work as it should, so an app will not start or will give errors, a text file shall be partially or entirely unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of information getting damaged without any identification by the system or an admin, that makes it a significant problem for web hosting servers as problems are more likely to happen on larger hard disk drives where considerable volumes of information are placed. In case a drive is a part of a RAID and the info on it is duplicated on other drives for redundancy, it's more than likely that the bad file will be treated as a regular one and it'll be duplicated on all of the drives, making the harm permanent. Lots of the file systems which operate on web servers these days often cannot locate corrupted files in real time or they need time-consuming system checks during which the server isn't operational.

No Data Corruption & Data Integrity in Website Hosting

We've dealt with the issue of silent data corruption on all of our website hosting servers by using the cutting-edge Z file system, or ZFS. The latter is more advanced than other file systems since it is the only one out there which checks all the files immediately by employing a checksum - a digital identifier which is unique for each and every file. When you upload content to your account, it will be stored on several NVMe drives and regularly synchronized between them for redundancy. ZFS regularly compares the checksum of all files and if any file is detected as corrupted, it is replaced immediately with a good copy from another disk. As this happens in real time, there's no risk that a bad file may remain or may be duplicated on the remaining NVMes. ZFS needs lots of physical memory to execute the real-time checks and the advantage of our cloud website hosting platform is that we work with multiple powerful servers working together. In case you host your sites with us, your info will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be shielded from silent data corruption since all our storage servers use the effective ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, in order to verify the integrity of each file. When you upload content to your account, it'll be stored on several redundant drives in a RAID i.e. the files will be the same on all drives. All copies of a specific file will have the same checksum on all drives and ZFS will compare the checksums of the duplicates quickly, so if it detects a mismatch, which will indicate that one of the copies is corrupted, it will replace that file with a good copy from one of the other drives. Even if there's a sudden blackout, the data on the servers won't be corrupted and there won't be any need for a time-consuming system check that other file systems perform after some failure, extending the time needed for the server to go back online. ZFS is the only file system that can truly protect your content from silent data corruption.
