Data corruption is the damage of info because of various software or hardware fails. After a file gets damaged, it will no longer function properly, so an app will not start or shall give errors, a text file could be partially or fully unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of data getting damaged without any identification by the system or an admin, that makes it a serious problem for hosting servers as failures are more likely to occur on larger hard drives where substantial volumes of information are placed. In case a drive is a part of a RAID and the data on it is duplicated on other drives for redundancy, it is very likely that the bad 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 that run on web servers today often cannot identify corrupted files in real time or they need time-consuming system checks during which the server is not operational.

No Data Corruption & Data Integrity in Shared Hosting

The integrity of the data which you upload to your new shared hosting account shall be guaranteed by the ZFS file system that we take advantage of on our cloud platform. The vast majority of web hosting service providers, like our firm, use multiple hard disks to store content and because the drives work in a RAID, the same info is synchronized between the drives all the time. If a file on a drive becomes damaged for some reason, yet, it is very likely that it will be reproduced on the other drives as alternative file systems don't include special checks for this. Unlike them, ZFS applies a digital fingerprint, or a checksum, for each file. In the event that a file gets corrupted, its checksum will not match what ZFS has as a record for it, so the bad copy shall be swapped with a good one from a different hard disk drive. Because this happens in real time, there is no risk for any of your files to ever get corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be shielded from silent data corruption because all our storage servers make use of the state-of-the-art ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, so as to ensure the integrity of every single file. When you upload content to your account, it will be stored on a couple of redundant drives employed in a RAID i.e. the files shall be the same across all disks. All copies of a particular file will feature the same checksum on all hard disks and ZFS will compare the checksums of the duplicates in real time, and if it registers a mismatch, which would indicate that one of the copies is corrupted, it will replace that file with a healthy copy from one of the other disks. Even if there's an unforeseen blackout, the data on the servers will not get corrupted and there will not be any need for a time-consuming system check which other file systems perform after some failure, extending the time needed for the server to return online. ZFS is the sole file system which can really protect your content from silent data corruption.
