Data corruption is the damage of data due to various software or hardware problems. The moment a file gets corrupted, it will no longer work properly, so an application will not start or shall give errors, a text file will be partially or entirely unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of information getting damaged without any acknowledgement by the system or an administrator, which makes it a serious problem for web hosting servers as problems are much more likely to happen on larger hard disks where vast volumes of info are located. If a drive is part of a RAID and the info on it is duplicated on other drives for redundancy, it's more than likely that the bad file will be treated as an ordinary one and it'll be copied on all of the drives, making the damage permanent. A huge number of the file systems that operate on web servers today often are not able to recognize corrupted files in real time or they need time-consuming system checks during which the server isn't working.
No Data Corruption & Data Integrity in Shared Web Hosting
The integrity of the data which you upload to your new shared web hosting
account will be guaranteed by the ZFS file system which we make use of on our cloud platform. The majority of hosting suppliers, like our firm, use multiple hard disks to keep content and since the drives work in a RAID, the exact same information is synchronized between the drives all of the time. If a file on a drive becomes corrupted for some reason, however, it's more than likely that it will be copied on the other drives since alternative file systems do not feature special checks for that. In contrast to them, ZFS applies a digital fingerprint, or a checksum, for each file. If a file gets damaged, its checksum won't match what ZFS has as a record for it, and the damaged copy shall be replaced with a good one from another hard disk drive. Since this happens in real time, there's no possibility for any of your files to ever be damaged.
No Data Corruption & Data Integrity in Semi-dedicated Servers
Your semi-dedicated server
account will be protected against silent data corruption because all of our storage servers make use of the state-of-the-art ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, to guarantee the integrity of each file. When you upload content to your account, it will be placed on a couple of redundant drives employed in a RAID i.e. the files will be the same across all drives. All the copies of a particular file will have the same checksum on all hard drives and ZFS will compare the checksums of the copies in real time, and 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 unexpected power failure, the data on the servers will not become corrupted and there will not 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 go back online. ZFS is the only file system which can truly protect your content from silent data corruption.
