Data corruption is the damage of data because of various software or hardware problems. When a file is damaged, it will no longer function accurately, so an application will not start or shall give errors, a text file could be partially or entirely unreadable, an archive file will be impossible to open and 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 serious problem for website hosting servers as failures are more likely to happen on larger hard disks where substantial volumes of information are stored. If a drive is part of a RAID and the information on it is replicated on other drives for redundancy, it is more than likely that the bad file will be treated as a regular one and will be duplicated on all drives, making the harm permanent. A huge number of the file systems which run on web servers today often cannot discover corrupted files immediately or they need time-consuming system checks during which the server is not operational.

No Data Corruption & Data Integrity in Shared Website Hosting

We have resolved the matter of silent data corruption on our shared website hosting servers by using the cutting-edge Z file system, or ZFS. The latter is better than other file systems because it is the only one in existence which checks all 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 frequently synced between them for redundancy. ZFS constantly analyzes the checksum of all files and in the event that any file is detected as damaged, it is replaced promptly with a good copy from another disk. As this happens in real time, there's no risk that a corrupted file may remain or may be duplicated on the rest of the SSDs. ZFS needs lots of physical memory to carry out 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 sites with us, your information will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

If you obtain one of our semi-dedicated server solutions, you will not need to worry about silent data corruption as we use ZFS - a high level file system which checks all files in real time. Every time you upload a file to your hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synced between several SSD drives for redundancy, so if one drive fails, the other ones will take control. ZFS compares the checksum of all of the copies on the different drives and if it detects a damaged copy, it replaces it with a healthy one from a different drive. This happens in real time, so there will be no threat for any part of your content at any time. In contrast, other file systems perform checks after a system breakdown, but since they do not use anything similar to the checksums which ZFS uses, they cannot detect silently corrupted files, so a corrupted copy may be replicated on the rest of the disks as well and you may lose precious information. Since this isn't the case with ZFS, we're able to warrant the integrity of every single file you upload no matter what.
