Data corruption is the damage of info due to various hardware or software failures. After a file is damaged, it will no longer work correctly, so an application will not start or shall give errors, a text file shall be partially or completely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of information getting harmed without any acknowledgement by the system or an admin, which makes it a significant problem for web hosting servers as fails are very likely to occur on bigger hard disk drives where substantial volumes of info are kept. When a drive is a part of a RAID and the data on it is replicated on other drives for redundancy, it is likely that the bad file will be treated as a good one and will be copied on all of the drives, making the damage permanent. Lots of the file systems that run on web servers these days often are unable to locate corrupted files in real time or they need time-consuming system checks through which the server is not operational.

No Data Corruption & Data Integrity in Cloud Website Hosting

We have dealt with the problem of silent data corruption on our cloud 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 right away by using a checksum - a digital identifier that is unique for each file. When you upload content to your account, it'll be stored on several SSD drives and continually synchronized between them for redundancy. ZFS constantly examines the checksum of all files and in the event that any file is detected as corrupted, it is replaced quickly with a good copy from another disk. As this happens in real time, there's no risk that a damaged file may remain or may be copied on the other SSDs. ZFS needs lots of physical memory to execute the real-time checks and the benefit of our cloud website hosting platform is that we use multiple very powerful servers working together. In case you host your Internet sites with us, your info will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We have avoided any chance of files getting damaged silently due to the fact that the servers where your semi-dedicated hosting account will be created work with a powerful file system named ZFS. Its basic advantage over alternative file systems is that it uses a unique checksum for each file - a digital fingerprint which is checked in real time. As we keep all content on numerous SSD drives, ZFS checks whether the fingerprint of a file on one drive matches the one on the other drives and the one it has saved. If there's a mismatch, the corrupted copy is replaced with a healthy one from one of the other drives and since this happens in real time, there is no chance that a damaged copy could remain on our web hosting servers or that it could be copied to the other drives in the RAID. None of the other file systems employ such checks and in addition, even during a file system check following a sudden power loss, none of them can discover silently corrupted files. In comparison, ZFS doesn't crash after an electrical power failure and the continual checksum monitoring makes a time-consuming file system check obsolete.
