Data corruption is the unintentional transformation of a file or the loss of info that often occurs during reading or writing. The reason could be hardware or software failure, and for that reason, a file may become partially or fully corrupted, so it will no longer work as it should since its bits will be scrambled or lost. An image file, for example, will no longer present a real image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, etc. In the event that such a problem appears and it is not identified by the system or by an admin, the data will become corrupted silently and if this happens on a disk drive that is part of a RAID array where the info is synced between various different drives, the corrupted file shall be duplicated on all the other drives and the harm will be permanent. A number of frequently used file systems either don't offer real-time checks or don't have high quality ones which can detect a problem before the damage is done, so silent data corruption is a rather common problem on internet hosting servers where substantial volumes of information are stored.
No Data Corruption & Data Integrity in Cloud Hosting
The integrity of the data which you upload to your new cloud hosting
account shall be ensured by the ZFS file system that we make use of on our cloud platform. The vast majority of internet hosting suppliers, including our firm, use multiple hard disk drives to store content and because the drives work in a RAID, the exact same data is synchronized between the drives at all times. If a file on a drive gets corrupted for some reason, yet, it's likely that it will be duplicated on the other drives since other file systems don't offer special checks for that. Unlike them, ZFS uses 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, therefore the bad copy shall be substituted with a good one from another hard disk drive. As this happens instantly, there's 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 shielded from silent data corruption as all of our storage servers make use of the efficient ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, so as to ensure the integrity of each and every file. When you upload content to your account, it'll be saved on several redundant drives in a RAID i.e. the files shall be the same on all disk drives. All copies of a specific file will have the same checksum on all hard drives and ZFS will compare the checksums of the copies quickly, and if it discovers a mismatch, which will indicate that one of the copies is damaged, it will replace that file with a healthy copy from one of the other disks. Even if there is an unexpected power failure, the data on the servers will not be corrupted and there will not be any need for a time-consuming system check that other file systems perform following some malfunction, prolonging the time needed for the server to go back online. ZFS is the sole file system that can really protect your content from silent data corruption.
