Data corruption is the unintended transformation of a file or the losing of info that usually occurs during reading or writing. The reason could be hardware or software failure, and for that reason, a file can become partially or fully corrupted, so it will no longer function as it should because its bits will be scrambled or lacking. An image file, for example, will no longer show a real image, but a random mix of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etcetera. When this kind of a problem appears and it isn't identified by the system or by an admin, the data will get corrupted silently and when this happens on a disk drive that's part of a RAID array where the information is synced between various drives, the corrupted file will be copied on all the other drives and the harm will become long term. Numerous frequently used file systems either do not have 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 very common problem on web hosting servers where huge amounts of data are kept.

No Data Corruption & Data Integrity in Shared Website Hosting

The integrity of the data that you upload to your new shared website hosting account shall be ensured by the ZFS file system that we take advantage of on our cloud platform. Most of the hosting suppliers, including our company, use multiple hard disk drives to store content and because the drives work in a RAID, identical info is synchronized between the drives all of the time. When a file on a drive gets damaged for some reason, yet, it is very likely that it will be copied on the other drives since alternative file systems do not have special checks for that. Unlike them, ZFS works with a digital fingerprint, or a checksum, for each file. In case a file gets damaged, its checksum will not match what ZFS has as a record for it, which means that the damaged copy will be swapped with a good one from another hard drive. Due to the fact that this happens immediately, there's no possibility for any of your files to ever be corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be resistant to silent data corruption since all our storage servers employ the advanced ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, in order to ensure the integrity of every single file. When you upload content to your account, it will be stored on a couple of redundant drives operating in a RAID i.e. the files will be the same on all disks. All copies of a given file will have the same checksum on all drives and ZFS will compare the checksums of the copies right away, and if it discovers a mismatch, which would indicate that one of the copies is corrupted, it'll replace that file with a healthy copy from one of the other disks. Even if there is an unforeseen blackout, 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 malfunction, extending the time needed for the server to return online. ZFS is the file system which can truly protect your content from silent data corruption.
