Data corruption is the damage of info because of various software or hardware failures. The moment a file is corrupted, it will no longer function as it should, so an app will not start or shall give errors, a text file can be partially or entirely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of data getting damaged without any acknowledgement by the system or an administrator, that makes it a significant problem for web hosting servers as fails are more likely to happen on larger in size hard drives where vast volumes of information are kept. If a drive is part of a RAID and the info on it is replicated on other drives for redundancy, it's more than likely that the damaged file will be treated as an ordinary one and it will be copied on all drives, making the harm permanent. A huge number of the file systems which operate on web servers today often are not able to discover corrupted files in real time or they need time-consuming system checks during which the server is not functioning.

No Data Corruption & Data Integrity in Shared Hosting

We've resolved the problem of silent data corruption on all of our shared hosting servers by using the hi-tech Z file system, or ZFS. The latter is more advanced than other file systems because it is the only one in existence which checks all the files right away by employing a checksum - a digital identifier that is unique for each file. When you upload content to your account, it will be stored on several SSD drives and constantly synced between them for redundancy. ZFS regularly examines the checksum of all files and in case any file is detected as damaged, it's replaced quickly with a good copy from another disk. As this happens in real time, there's no risk that a damaged file may remain or may be duplicated on the rest of the SSDs. ZFS needs lots of physical memory to execute the real-time checks and the advantage of our cloud website hosting platform is that we work with multiple very powerful servers working together. If you host your websites with us, your info will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

If you purchase one of our semi-dedicated server solutions, you will not need to worry about silent file corruption as we use ZFS - an advanced file system that monitors all of the 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. This file will be synchronized between a number of SSD drives for redundancy, so if a drive fails, the other ones will take over. ZFS compares the checksum of all the copies on the different drives and in case it detects a damaged copy, it replaces it with a healthy one from a different drive. This happens right away, so there will be no risk for any part of your content at any moment. In contrast, all the other file systems perform checks after a system malfunction, but since they do not use anything similar to the checksums which ZFS uses, they are unable to detect silently corrupted files, so a corrupted copy can be replicated on the other disks as well and you can lose crucial data. Since this is not the case with ZFS, we're able to warrant the integrity of each and every file you upload no matter what.
