Data corruption is the damage of info due to various software or hardware failures. When a file is damaged, it will no longer function properly, so an app will not start or shall give errors, a text file could be partially or entirely unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of information getting damaged without any acknowledgement by the system or an administrator, that makes it a serious problem for web hosting servers as fails are more likely to occur on larger in size hard disk drives where substantial volumes of info are located. When a drive is a part of a RAID and the data on it is copied on other drives for redundancy, it is very likely that the damaged file will be treated as an undamaged one and it'll be duplicated on all the drives, making the harm permanent. A huge number of the file systems that operate on web servers nowadays often are not able to discover corrupted files right away or they need time-consuming system checks through which the server isn't working.

No Data Corruption & Data Integrity in Shared Hosting

We have resolved the problem of silent data corruption on all of our shared hosting servers by using the cutting-edge Z file system, or ZFS. The latter is better than other file systems as it is the only one in existence that checks all the files instantly by using a checksum - a digital identifier that is unique for every single file. When you upload content to your account, it'll be stored on several NVMe drives and continually synced between them for redundancy. ZFS regularly examines the checksum of all files and in the event that any file is detected as corrupted, it's replaced right away with a good copy from some other disk. As this happens in real time, there's no risk that a corrupted file may remain or may be copied on the rest of the NVMes. ZFS needs a lot of physical memory in order to perform the real-time checks and the advantage of our cloud web hosting platform is that we employ 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 Hosting

You will not have to deal with any silent data corruption issues should you buy one of our semi-dedicated hosting solutions because the ZFS file system that we take advantage of on our cloud hosting platform uses checksums to make sure that all the files are intact all of the time. A checksum is a unique digital fingerprint which is allotted to each and every file saved on a server. Due to the fact that we store all content on a number of drives at the same time, the same file has the same checksum on all the 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 out there that uses checksums, which makes it much more dependable than other file systems that are unable to detect silent data corruption and copy bad files across drives.
