Data corruption is the damage of information due to various hardware or software problems. When a file is damaged, it will no longer function correctly, so an app will not start or will give errors, a text file will be partially or entirely unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of info getting damaged without any acknowledgement by the system or an admin, that makes it a significant problem for hosting servers as fails are more likely to occur on larger hard disks where substantial volumes of information are kept. In case a drive is a part of a RAID and the data on it is replicated on other drives for redundancy, it's very likely that the damaged file will be treated as a healthy one and will be duplicated on all the drives, making the damage permanent. A lot of the file systems which operate on web servers nowadays often are unable to find corrupted files in real time or they need time-consuming system checks during which the server isn't functioning.

No Data Corruption & Data Integrity in Shared Hosting

The integrity of the data that you upload to your new shared hosting account shall be guaranteed by the ZFS file system which we make use of on our cloud platform. The vast majority of hosting suppliers, including our company, use multiple hard disks to keep content and since the drives work in a RAID, the same information is synchronized between the drives all of the time. When a file on a drive becomes damaged for reasons unknown, however, it is very likely that it will be reproduced on the other drives since alternative file systems do not include special checks for that. Unlike them, ZFS employs a digital fingerprint, or a checksum, for every single file. In the event that a file gets damaged, its checksum won't match what ZFS has as a record for it, and the damaged copy will be replaced with a good one from a different disk drive. Because 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 Hosting

Your semi-dedicated hosting account will be resistant to silent data corruption because all our storage servers make use of the reliable ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, in order to ensure the integrity of each and every file. When you upload content to your account, it'll be stored on several redundant drives operating in a RAID i.e. the files will be the same on all drives. All the 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 identifies a mismatch, which will indicate that one of the copies is corrupted, it'll substitute that file with a good 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 that other file systems perform following some malfunction, extending the time needed for the server to get back online. ZFS is the sole file system that can truly protect your content from silent data corruption.
