Data corruption is the damage of information because of various hardware or software fails. Once a file gets corrupted, it will no longer function correctly, so an application will not start or shall give errors, a text file shall be partially or entirely 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 acknowledgement by the system or an admin, which makes it a significant problem for web hosting servers as failures are very likely to happen on bigger hard disk drives where large volumes of info are kept. When a drive is a part of a RAID and the info on it is duplicated on other drives for redundancy, it's likely that the damaged file will be treated as an ordinary one and it will be duplicated on all of the drives, making the harm permanent. Lots of the file systems which run on web servers these days often are not able to detect corrupted files immediately or they need time-consuming system checks through which the server is not operational.

No Data Corruption & Data Integrity in Hosting

We've resolved the problem of silent data corruption on all our hosting servers by using the state-of-the-art Z file system, or ZFS. The latter is superior to other file systems because it is the only one out there which checks all of the files immediately by using a checksum - a digital identifier that's unique for every single file. When you upload content to your account, it'll be stored on several SSD drives and frequently synchronized between them for redundancy. ZFS constantly analyzes the checksum of all files and if any file is detected as damaged, it is replaced immediately 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 copied on the other SSDs. ZFS requires lots 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 powerful servers working together. If you host your websites with us, your information will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be shielded from silent data corruption as all of our storage servers work with the effective ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, in order to guarantee the integrity of each and every file. When you upload content to your account, it'll be saved on several redundant drives employed in a RAID i.e. the files will be the same on all drives. All copies of a specific file will have the same checksum on all drives and ZFS will compare the checksums of the duplicates quickly, so if it discovers a mismatch, that would indicate that one of the copies is corrupted, it'll replace that file with a good copy from one of the other drives. Even if there is an unexpected power failure, the data on the servers will not become corrupted and there will not be any need for a time-consuming system check that other file systems perform after some malfunction, prolonging the time needed for the server to return online. ZFS is the sole file system that can really protect your content from silent data corruption.
