Data corruption is the damage of information caused by various software or hardware problems. The moment a file is corrupted, it will no longer work correctly, so an app will not start or shall give errors, a text file can be partially or completely unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of information getting harmed without any identification by the system or an administrator, that makes it a serious problem for website hosting servers as problems are much more likely to happen on bigger hard drives where vast volumes of info are located. If a drive is a part of a RAID and the data on it is copied on other drives for redundancy, it is likely that the bad file will be treated as a regular one and will be duplicated on all drives, making the harm permanent. A lot of the file systems which operate on web servers nowadays often are unable to recognize corrupted files in real time or they need time-consuming system checks during which the server isn't operational.

No Data Corruption & Data Integrity in Shared Website Hosting

We have tackled the matter of silent data corruption on all our shared website hosting servers by using the modern Z file system, or ZFS. The latter is superior to other file systems because it is the only one on the market which checks all of the files immediately by using a checksum - a digital identifier that's unique for each file. When you upload content to your account, it'll be stored on several SSD drives and constantly synchronized between them for redundancy. ZFS constantly analyzes the checksum of all files and if any file is detected as corrupted, it's replaced immediately with a good copy from some other disk. As this happens in real time, there is no risk that a corrupted file may remain or may be duplicated on the rest of the SSDs. ZFS needs a lot of physical memory in order to carry out the real-time checks and the benefit of our cloud website hosting platform is that we work with multiple very powerful servers working together. In case you host your sites with us, your info will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be protected against silent data corruption as all our storage servers employ the state-of-the-art ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, to verify the integrity of every single file. When you upload content to your account, it'll be kept on a couple of redundant drives operating in a RAID i.e. the files shall be the same across all disks. All the copies of a given file will feature the same checksum on all drives and ZFS will compare the checksums of the copies right away, and if it registers a mismatch, which will indicate that one of the copies is damaged, it'll replace that file with a healthy copy from one of the other disks. Even if there is a sudden power failure, the data on the servers will not be corrupted and there will not be any need for a time-consuming system check that other file systems perform following some failure, prolonging the time needed for the server to get back online. ZFS is the sole file system that can really protect your content from silent data corruption.
