Data corruption is the damage of data caused by various software or hardware problems. After a file gets corrupted, it will no longer work correctly, so an application will not start or shall give errors, a text file can be partially or completely unreadable, an archive file will be impossible to open and unpack, etc. Silent data corruption is the process of info getting harmed without any identification by the system or an admin, which makes it a significant problem for web hosting servers as failures are very likely to happen on bigger hard disks where vast volumes of information are stored. If a drive is part of a RAID and the data on it is replicated on other drives for redundancy, it is more than likely that the damaged file will be treated as a regular one and it will be copied on all of the drives, making the damage permanent. Lots of the file systems which operate on web servers nowadays often are unable to identify corrupted files instantly or they need time-consuming system checks through which the server is not operational.

No Data Corruption & Data Integrity in Web Hosting

The integrity of the data which you upload to your new web hosting account will be ensured by the ZFS file system that we use on our cloud platform. The vast majority of internet hosting suppliers, like our company, use multiple hard drives to keep content and because the drives work in a RAID, exactly the same info is synchronized between the drives at all times. When a file on a drive becomes corrupted for reasons unknown, however, it is very likely that it will be duplicated on the other drives because alternative file systems do not feature special checks for that. Unlike them, ZFS works with a digital fingerprint, or a checksum, for each file. In case a file gets corrupted, its checksum will not match what ZFS has as a record for it, therefore the damaged copy shall be replaced with a good one from another hard disk drive. Since this happens instantly, there's no possibility for any of your files to ever get 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 efficient ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, in order to verify the integrity of each file. When you upload content to your account, it will be placed on several redundant drives in a RAID i.e. the files shall be the same across all drives. All copies of a specific file will feature the same checksum on all hard drives and ZFS will compare the checksums of the duplicates quickly, so if it identifies a mismatch, which will indicate that one of the copies is damaged, it'll replace that file with a healthy copy from one of the other drives. Even if there is an unforeseen power loss, the data on the servers will not get corrupted and there won't be any need for a time-consuming system check which other file systems perform following some breakdown, lengthening the time needed for the server to return online. ZFS is the sole file system that can truly protect your content from silent data corruption.
