Data corruption is the damage of information because of various software or hardware problems. When a file is corrupted, it will no longer work accurately, so an application will not start or shall give errors, a text file could be partially or completely unreadable, an archive 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 administrator, that makes it a significant problem for website hosting servers as failures are very likely to happen on bigger hard drives where substantial volumes of info are located. When a drive is a 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 standard one and it'll be duplicated on all drives, making the harm permanent. A lot of the file systems which run on web servers today often are unable to recognize corrupted files instantly or they need time-consuming system checks through which the server isn't functioning.

No Data Corruption & Data Integrity in Shared Web Hosting

We've resolved the matter of silent data corruption on all our shared web hosting servers by using the state-of-the-art Z file system, or ZFS. The latter is more advanced than other file systems as it is the only one on the market 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 continually synchronized between them for redundancy. ZFS constantly analyzes 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 a lot of physical memory to carry out the real-time checks and the advantage of our cloud website hosting platform is that we take advantage of multiple very powerful servers working together. If you host your sites with us, your info will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

You won't experience any silent data corruption issues whatsoever if you purchase one of our semi-dedicated hosting solutions as the ZFS file system that we take advantage of on our cloud hosting platform uses checksums in order to ensure that all files are intact all of the time. A checksum is a unique digital fingerprint which is allotted to each and every file kept on a server. Due to the fact that we store all content on a number of drives simultaneously, the same file has the same checksum on all drives and what ZFS does is that it compares the checksums between the different drives in real time. In the event that 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 right away, avoiding any chance of the damaged copy to be synchronized on the rest of the hard drives. ZFS is the only file system you will find which uses checksums, which makes it much more dependable than other file systems which are not able to identify silent data corruption and duplicate bad files across hard drives.
