Data corruption is the damage of info due to various software or hardware problems. Once a file gets corrupted, it will no longer function as it should, so an app will not start or shall give errors, a text file will be partially or fully unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of data getting damaged without any acknowledgement by the system or an admin, which makes it a serious problem for hosting servers as failures are more likely to happen on larger in size hard disks where significant volumes of information are kept. If a drive is part of a RAID and the data on it is replicated on other drives for redundancy, it is likely that the damaged file will be treated as a healthy one and it will be duplicated on all the drives, making the harm permanent. A lot of the file systems which run on web servers nowadays often are not able to discover corrupted files immediately or they need time-consuming system checks during which the server isn't working.

No Data Corruption & Data Integrity in Shared Web Hosting

The integrity of the data that you upload to your new shared web hosting account will be guaranteed by the ZFS file system that we employ on our cloud platform. The majority of internet hosting providers, including our company, use multiple hard disk drives to store content and since the drives work in a RAID, the exact same information is synchronized between the drives at all times. If a file on a drive gets damaged for reasons unknown, however, it's likely that it will be duplicated on the other drives as alternative file systems do not feature special checks for that. Unlike them, ZFS employs a digital fingerprint, or a checksum, for every file. If a file gets damaged, 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. As this happens in real time, there's no possibility 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 resistant to silent data corruption since all of our storage servers employ the state-of-the-art ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, so as to ensure the integrity of each file. When you upload content to your account, it will be saved on a couple of redundant drives employed in a RAID i.e. the files shall be the same on all disks. All the copies of a specific file will have the same checksum on all hard disks and ZFS will compare the checksums of the copies right away, and if it discovers a mismatch, which will indicate that one of the copies is damaged, it will swap that file with a healthy copy from one of the other disks. Even if there is an unexpected blackout, the data on the servers will not become corrupted and there won't be any need for a time-consuming system check which other file systems perform following some breakdown, extending the time needed for the server to return online. ZFS is the sole file system which can truly protect your content from silent data corruption.
