Data corruption is the damage of data because of various hardware or software failures. Once a file is damaged, it will no longer function accurately, so an app will not start or shall give errors, a text file could be partially or fully unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of information getting damaged without any identification by the system or an admin, that makes it a significant problem for hosting servers as problems are very likely to occur on larger in size hard disks where vast volumes of information are stored. When a drive is a part of a RAID and the information on it is duplicated on other drives for redundancy, it's more than likely that the bad file will be treated as a standard one and it will be copied on all drives, making the harm permanent. Lots of the file systems that run on web servers today often are not able to locate corrupted files instantly or they need time-consuming system checks through which the server isn't working.
No Data Corruption & Data Integrity in Shared Hosting
The integrity of the data which you upload to your new shared hosting
account shall be guaranteed by the ZFS file system that we work with on our cloud platform. The majority of hosting providers, like our firm, use multiple hard drives to keep content and considering that the drives work in a RAID, the exact same information is synchronized between the drives at all times. In case a file on a drive becomes corrupted for whatever reason, however, it's more than likely that it will be copied on the other drives because other file systems do not have special checks for that. Unlike them, ZFS works with 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, which means that the damaged copy shall be substituted with a good one from a different drive. As this happens in real time, there is no possibility 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 protected against silent data corruption because all our storage servers make use of the efficient ZFS file system. What makes the latter 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 will be kept on a couple of redundant drives being employed in a RAID i.e. the files will be the same on all disks. All of the copies of a particular file will have the same checksum on all hard drives and ZFS will compare the checksums of the copies right away, so if it discovers a mismatch, which will indicate that one of the copies is damaged, it'll swap that file with a good copy from one of the other drives. Even if there's an unforeseen power failure, the data on the servers will not be corrupted and there won't be any need for a time-consuming system check that other file systems perform following some failure, extending the time needed for the server to get back online. ZFS is the sole file system which can really protect your content from silent data corruption.
