Data corruption is the damage of information because of various software or hardware problems. The moment a file is corrupted, it will no longer work properly, so an application will not start or will give errors, a text file could be partially or entirely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of info getting harmed without any identification by the system or an admin, that makes it a serious problem for hosting servers as fails are very likely to occur on bigger hard disks where substantial volumes of information are stored. In case 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 a healthy one and it will be duplicated on all of the drives, making the harm permanent. A huge number of the file systems that run on web servers these days often are unable to locate corrupted files in real time 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 which you upload to your new shared hosting
account shall be ensured by the ZFS file system which we use on our cloud platform. Most of the internet hosting providers, including our firm, use multiple hard drives to store content and considering that the drives work in a RAID, identical info is synchronized between the drives all the time. When a file on a drive becomes corrupted for whatever reason, yet, it is more than likely that it will be duplicated on the other drives as other file systems do not feature special checks for that. In contrast to them, ZFS uses a digital fingerprint, or a checksum, for every file. In the event that a file gets corrupted, its checksum won't match what ZFS has as a record for it, which means that the damaged copy shall be swapped with a good one from a different disk drive. As this happens instantly, there is 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 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, so as to ensure 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 on all disk drives. All of the copies of a specific file will feature the same checksum on all drives and ZFS will compare the checksums of the duplicates quickly, so if it discovers a mismatch, that will indicate that one of the copies is damaged, it will replace that file with a healthy copy from one of the other drives. Even if there is an unexpected power loss, the data on the servers will not get corrupted and there won't be any need for a time-consuming system check that other file systems perform after some failure, lengthening the time needed for the server to return online. ZFS is the file system that can truly protect your content from silent data corruption.
