Data corruption is the damage of information caused by various hardware or software problems. The moment a file gets damaged, it will no longer function properly, so an application will not start or shall give errors, a text file could be partially or entirely unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of info getting damaged without any identification by the system or an administrator, that makes it a serious problem for web hosting servers as fails are more likely to happen on larger in size hard disks where vast volumes of info are placed. If a drive is part of a RAID and the information on it is replicated on other drives for redundancy, it is likely that the bad file will be treated as a regular one and it'll be duplicated on all drives, making the damage permanent. Lots of the file systems which operate on web servers these days often cannot find 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 Hosting

The integrity of the data which you upload to your new cloud hosting account shall be guaranteed by the ZFS file system which we make use of on our cloud platform. The majority of web hosting service providers, like our company, use multiple HDDs to keep content and because the drives work in a RAID, exactly the same information is synchronized between the drives at all times. When a file on a drive becomes damaged for some reason, however, it is likely that it will be duplicated on the other drives since other file systems don't offer special checks for this. In contrast to them, ZFS applies a digital fingerprint, or a checksum, for each file. If a file gets corrupted, its checksum won't match what ZFS has as a record for it, therefore the bad copy will be swapped with a good one from a different drive. Because this happens in real time, there's no possibility 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 because all our storage servers employ the state-of-the-art ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, to ensure the integrity of each file. When you upload content to your account, it'll be kept on a couple of redundant drives being employed in a RAID i.e. the files will be the same on all disk drives. All of the copies of a given file will have the same checksum on all hard disks and ZFS will compare the checksums of the copies quickly, so if it identifies a mismatch, which will indicate that one of the copies is damaged, it'll substitute that file with a good copy from one of the other disks. Even if there is an unforeseen power failure, 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 following some malfunction, lengthening the time needed for the server to return online. ZFS is the only file system which can really protect your content from silent data corruption.
