Data corruption is the damage of info due to various hardware or software failures. The moment a file gets damaged, it will no longer work properly, so an application will not start or will give errors, a text file could be partially or entirely unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of data getting harmed without any identification by the system or an administrator, that makes it a serious problem for website hosting servers as problems are much more likely to occur on bigger hard disk drives where large volumes of information are located. In case a drive is part of a RAID and the data on it is copied on other drives for redundancy, it's very likely that the bad file will be treated as an undamaged one and will be copied on all of the drives, making the harm permanent. A lot of the file systems which operate on web servers nowadays often are unable to locate corrupted files immediately or they need time-consuming system checks during which the server is not 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 ensured by the ZFS file system that we make use of on our cloud platform. Most of the web hosting providers, including our company, use multiple HDDs to store content and since the drives work in a RAID, the same info is synchronized between the drives all of the time. If a file on a drive becomes damaged for whatever reason, yet, it is likely that it will be duplicated on the other drives since other file systems don't include special checks for that. Unlike them, ZFS works with 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, and the bad copy shall be swapped with a good one from another hard disk. Because this happens in real time, there's no risk for any of your files to ever be corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be resistant to silent data corruption since all our storage servers use the reliable ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, in order to ensure the integrity of each file. When you upload content to your account, it will be stored on a couple of redundant drives in a RAID i.e. the files will 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 copies quickly, and if it finds a mismatch, which will indicate that one of the copies is corrupted, it will swap that file with a healthy copy from one of the other drives. Even if there's an unexpected blackout, the data on the servers won't become corrupted and there won't be any need for a time-consuming system check that other file systems perform after some failure, extending the time needed for the server to return online. ZFS is the file system that can truly protect your content from silent data corruption.
