Data corruption is the damage of data because of various hardware or software fails. When a file gets corrupted, it will no longer function as it should, so an application will not start or shall give errors, a text file can 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 harmed without any identification by the system or an administrator, that makes it a serious problem for web hosting servers as failures are much more likely to happen on larger hard drives where vast volumes of info are located. In case a drive is part of a RAID and the data on it is copied on other drives for redundancy, it is very likely that the damaged file will be treated as a healthy one and it'll be duplicated on all drives, making the damage permanent. Lots of the file systems which operate on web servers nowadays often cannot find corrupted files instantly or they need time-consuming system checks through which the server is not 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 ensured by the ZFS file system that we employ on our cloud platform. Most hosting providers, like our firm, use multiple hard drives to store content and because the drives work in a RAID, identical information is synchronized between the drives all the time. When a file on a drive is corrupted for whatever reason, yet, it's very likely that it will be reproduced on the other drives since other file systems do not feature special checks for that. In contrast to them, ZFS uses a digital fingerprint, or a checksum, for each file. In the event that a file gets corrupted, its checksum won't match what ZFS has as a record for it, so the bad copy shall be replaced with a good one from another disk drive. As this happens right away, 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 shielded from silent data corruption as all our storage servers make use of the innovative ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, to verify the integrity of every single file. When you upload content to your account, it'll be placed on several redundant drives being employed in a RAID i.e. the files will be the same across all disk drives. All the copies of a given file will feature the same checksum on all drives and ZFS will compare the checksums of the duplicates in real time, and if it registers a mismatch, which will indicate that one of the copies is damaged, it'll swap that file with a healthy copy from one of the other drives. Even if there's an unexpected power failure, the data on the servers won't get corrupted and there won't be any need for a time-consuming system check that other file systems perform after some failure, prolonging the time needed for the server to return online. ZFS is the sole file system that can really protect your content from silent data corruption.
