Data corruption is the damage of info due to various hardware or software fails. After a file is damaged, it will no longer work accurately, so an app will not start or will give errors, a text file shall be partially or completely unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of info getting damaged without any identification by the system or an administrator, which makes it a serious problem for hosting servers as failures are very likely to occur on bigger hard drives where large volumes of information are located. If a drive is a part of a RAID and the information on it is duplicated on other drives for redundancy, it is more than likely that the bad file will be treated as an ordinary one and it will be duplicated on all the drives, making the harm permanent. Lots of the file systems that run on web servers these days often cannot locate corrupted files right away or they need time-consuming system checks during which the server is not operational.

No Data Corruption & Data Integrity in Cloud Hosting

The integrity of the data which you upload to your new cloud hosting account will be ensured by the ZFS file system which we work with on our cloud platform. Most of the web hosting service providers, like our company, use multiple hard drives to keep content and because the drives work in a RAID, identical data is synchronized between the drives all of the time. If a file on a drive becomes corrupted for reasons unknown, yet, it's more than likely that it will be duplicated on the other drives because other file systems don't feature special checks for this. In contrast to them, ZFS employs a digital fingerprint, or a checksum, for each and every file. In the event that a file gets damaged, its checksum will not match what ZFS has as a record for it, therefore the bad copy will be substituted with a good one from a different drive. As this happens immediately, there is no risk for any of your files to ever get damaged.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be protected against silent data corruption because all our storage servers employ the state-of-the-art ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, to guarantee the integrity of each file. When you upload content to your account, it'll be placed on a couple of redundant drives operating in a RAID i.e. the files will be the same across all disks. All of the copies of a specific file will feature the same checksum on all hard drives and ZFS will compare the checksums of the copies in real time, and if it finds 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 loss, the data on the servers will not get corrupted and there won't be any need for a time-consuming system check which other file systems perform after some failure, prolonging the time needed for the server to return online. ZFS is the file system that can truly protect your content from silent data corruption.
