Data corruption is the damage of data due to various software or hardware failures. After a file is corrupted, it will no longer function accurately, so an app will not start or shall give errors, a text file will be partially or completely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of info getting harmed without any identification by the system or an administrator, which makes it a significant problem for website hosting servers as failures are very likely to happen on larger hard drives where large volumes of information are stored. When a drive is part of a RAID and the data on it is replicated 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 damage permanent. A huge number of the file systems that operate on web servers nowadays often cannot find corrupted files right away or they need time-consuming system checks through which the server is not functioning.

No Data Corruption & Data Integrity in Hosting

We have dealt with the matter of silent data corruption on all of our hosting servers by using the leading-edge Z file system, or ZFS. The latter is more advanced than other file systems because it is the only one out there which checks all files immediately by employing 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 SSD drives and continually synced between them for redundancy. ZFS regularly analyzes the checksum of all files and when any file is detected as corrupted, it's replaced right away 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 remaining SSDs. ZFS needs plenty of physical memory to carry out the real-time checks and the advantage of our cloud website hosting platform is that we work with multiple very powerful servers working together. In case you host your Internet sites with us, your data will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

You won't need to deal with any silent data corruption issues should you purchase one of our semi-dedicated hosting packages as the ZFS file system that we work with on our cloud hosting platform uses checksums in order to guarantee that all of your files are intact all the time. A checksum is a unique digital fingerprint which is allotted to each and every file saved on a server. Because we store all content on multiple drives at the same time, 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. In case 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 other drives. ZFS is the sole file system out there which uses checksums, which makes it much more dependable than other file systems which are not able to detect silent data corruption and duplicate bad files across hard drives.
