Data corruption is the damage of information due to various software or hardware failures. Once a file gets corrupted, it will no longer work properly, so an application will not start or will give errors, a text file can be partially or fully unreadable, an archive file will be impossible to open and unpack, etc. Silent data corruption is the process of info getting damaged without any identification by the system or an admin, that makes it a serious problem for hosting servers as problems are much more likely to happen on bigger hard disks where large volumes of info are placed. If a drive is part of a RAID and the info on it is copied on other drives for redundancy, it's more than likely that the bad file will be treated as a healthy one and will be duplicated on all of the drives, making the harm permanent. Lots of the file systems that operate on web servers today often are unable to 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 Hosting

We've resolved the matter of silent data corruption on all of our 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 on the market which checks all the files in real time by employing a checksum - a digital identifier which is unique for each 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 compares the checksum of all files and in case any file is detected as corrupted, it is replaced promptly 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 duplicated on the rest of the SSDs. ZFS needs plenty of physical memory in order to perform the real-time checks and the benefit of our cloud hosting platform is that we take advantage of multiple powerful servers working together. If you host your websites with us, your data will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

You won't have to deal with any silent data corruption issues whatsoever should you obtain one of our semi-dedicated hosting solutions due to the fact that the ZFS file system that we work with on our cloud hosting platform uses checksums in order to make sure that all the files are intact at all times. A checksum is a unique digital fingerprint which is allotted to each and every file stored on a server. Since we store all content on a number of drives simultaneously, the same file uses the same checksum on all drives and what ZFS does is that it compares the checksums between the different drives right away. When it detects that a file is corrupted and its checksum is different from what it should be, it replaces that file with a healthy copy without delay, avoiding any chance of the damaged copy to be synchronized on the remaining hard drives. ZFS is the sole file system you will find that uses checksums, which makes it much more dependable than other file systems which are unable to identify silent data corruption and copy bad files across drives.
