Data corruption is the damage of data due to various hardware or software failures. Once a file is corrupted, it will no longer function correctly, so an application will not start or shall give errors, a text file can be partially or completely unreadable, an archive file 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 admin, that makes it a serious problem for website hosting servers as failures are much more likely to occur on larger in size hard disk drives where significant volumes of info are kept. When a drive is part of a RAID and the info on it is replicated on other drives for redundancy, it's likely that the bad file will be treated as a good one and it will be copied on all of the drives, making the damage permanent. A lot of the file systems which operate on web servers nowadays often are unable to detect 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 Web Hosting

The integrity of the data that you upload to your new cloud web hosting account shall be guaranteed by the ZFS file system which we use on our cloud platform. Most web hosting service providers, like our company, use multiple hard disks to keep content and considering that the drives work in a RAID, exactly the same information is synchronized between the drives at all times. When a file on a drive gets damaged for reasons unknown, yet, it is very likely that it will be copied on the other drives because other file systems do not include special checks for that. In contrast to them, ZFS employs a digital fingerprint, or a checksum, for each and every file. In the event that a file gets corrupted, its checksum will not match what ZFS has as a record for it, therefore the bad copy will be replaced with a good one from another hard disk drive. Since this happens right away, there's no risk for any of your files to ever get damaged.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be shielded from silent data corruption because all of our storage servers make use of the efficient ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, so as to guarantee the integrity of each file. When you upload content to your account, it will be saved on a couple of redundant drives being employed in a RAID i.e. the files shall be the same on all disk drives. All copies of a given file will have the same checksum on all hard drives and ZFS will compare the checksums of the duplicates right away, and if it finds a mismatch, that would indicate that one of the copies is damaged, it will replace that file with a good copy from one of the other drives. Even if there's an unexpected power loss, the data on the servers won't be corrupted and there won't be any need for a time-consuming system check which other file systems perform following some malfunction, prolonging the time needed for the server to return online. ZFS is the file system that can really protect your content from silent data corruption.
