Data corruption is the damage of info due to various hardware or software failures. When a file gets damaged, it will no longer work properly, so an application will not start or shall give errors, a text file could be partially or fully unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of information getting harmed without any identification by the system or an administrator, which makes it a significant problem for website hosting servers as fails are very likely to happen on bigger hard disk drives where significant volumes of information are stored. When a drive is a part of a RAID and the info on it is replicated on other drives for redundancy, it is likely that the bad file will be treated as an undamaged one and will be copied on all drives, making the damage permanent. A lot of the file systems which operate on web servers these days often are unable to recognize corrupted files in real time or they need time-consuming system checks during which the server is not working.

No Data Corruption & Data Integrity in Website Hosting

We've resolved the matter of silent data corruption on all of our website hosting servers by using the modern Z file system, or ZFS. The latter is better than other file systems as it is the only one on the market which checks all the files instantly by employing a checksum - a digital identifier which is unique for every single file. When you upload content to your account, it will be stored on several SSD drives and constantly synced between them for redundancy. ZFS constantly analyzes the checksum of all files and in case any file is detected as corrupted, it is replaced right away with a good copy from another disk. As this happens in real time, there is no risk that a damaged file may remain or may be copied on the rest of the SSDs. ZFS requires plenty of physical memory in order to execute the real-time checks and the benefit of our cloud web hosting platform is that we use multiple very powerful servers working together. If you host your Internet 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 employ the advanced ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, to ensure the integrity of each file. When you upload content to your account, it'll be kept on a couple of redundant drives in a RAID i.e. the files will be the same across all disk drives. All copies of a given file will feature the same checksum on all drives and ZFS will compare the checksums of the copies right away, and if it identifies a mismatch, that will indicate that one of the copies is corrupted, it will replace 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 be corrupted and there will not be any need for a time-consuming system check which other file systems perform after some malfunction, extending the time needed for the server to return online. ZFS is the file system that can truly protect your content from silent data corruption.
