Data corruption is the damage of information because of various software or hardware failures. The moment a file gets damaged, it will no longer function as it should, so an application will not start or shall give errors, a text file could be partially or completely unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of info getting harmed without any acknowledgement by the system or an admin, which makes it a significant problem for hosting servers as failures are more likely to occur on bigger hard disks where large volumes of info are stored. In case a drive is a part of a RAID and the info on it is duplicated on other drives for redundancy, it's likely that the damaged file will be treated as a good one and will be copied on all of the drives, making the harm permanent. Lots of the file systems which run on web servers nowadays often are not able to identify corrupted files immediately or they need time-consuming system checks during which the server is not functioning.

No Data Corruption & Data Integrity in Shared Website Hosting

We have resolved the problem of silent data corruption on all of our shared website hosting servers by using the state-of-the-art Z file system, or ZFS. The latter is superior to other file systems since it is the only one on the market that checks all the files right away by employing a checksum - a digital identifier which is unique for every single file. When you upload content to your account, it'll be stored on several SSD drives and frequently synchronized between them for redundancy. ZFS constantly compares the checksum of all files and when any file is detected as damaged, it is replaced instantly 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 copied on the remaining SSDs. ZFS needs lots of physical memory in order to execute the real-time checks and the benefit of our cloud web hosting platform is that we work with multiple very powerful servers working together. If you host your websites with us, your information will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You will not encounter any silent data corruption issues whatsoever should you get one of our semi-dedicated server solutions since the ZFS file system that we use on our cloud hosting platform uses checksums to make sure that all the files are undamaged all the time. A checksum is a unique digital fingerprint which is assigned to each and every file saved on a server. Because we store all content on multiple drives simultaneously, the same file uses the same checksum on all the drives and what ZFS does is that it compares the checksums between the different drives right away. If 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 possibility of the damaged copy to be synchronized on the remaining hard drives. ZFS is the only file system you can get that uses checksums, which makes it much more reliable than other file systems that cannot detect silent data corruption and copy bad files across hard drives.
