Data corruption is the accidental transformation of a file or the loss of info which usually occurs during reading or writing. The reason can be hardware or software failure, and because of this, a file may become partially or fully corrupted, so it will no longer function correctly as its bits will be scrambled or missing. An image file, for instance, will no longer show an accurate image, but a random combination of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, and so on. When this kind of an issue occurs and it is not noticed by the system or by an admin, the data will be corrupted silently and in case this happens on a drive that's part of a RAID array where the data is synchronized between various different drives, the corrupted file shall be replicated on all the other drives and the damage will be long term. Many widely used file systems either don't feature real-time checks or don't have good ones that will detect an issue before the damage is done, so silent data corruption is a common problem on hosting servers where large amounts of info are kept.

No Data Corruption & Data Integrity in Shared Website Hosting

The integrity of the data which you upload to your new shared website hosting account will be ensured by the ZFS file system that we use on our cloud platform. The vast majority of web hosting providers, like our firm, use multiple hard disks to store content and because the drives work in a RAID, identical info is synchronized between the drives all the time. In case a file on a drive becomes damaged for reasons unknown, yet, it is very likely that it will be duplicated on the other drives as other file systems don't feature special checks for this. In contrast to them, ZFS uses a digital fingerprint, or a checksum, for every single file. In case a file gets corrupted, its checksum won't match what ZFS has as a record for it, therefore the damaged copy will be substituted with a good one from another disk drive. Because this happens right away, 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 resistant to silent data corruption as all of our storage servers make use of the innovative ZFS file system. What makes the latter 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 stored on a couple of redundant drives in a RAID i.e. the files shall be the same on all disks. All the copies of a given file will have the same checksum on all hard disks and ZFS will compare the checksums of the duplicates in real time, so if it finds a mismatch, that will indicate that one of the copies is damaged, it'll replace that file with a good copy from one of the other drives. Even if there is an unexpected power loss, the data on the servers will not become corrupted and there won't be any need for a time-consuming system check which other file systems perform following 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.
