Data corruption is the accidental transformation of a file or the loss of info which usually occurs during reading or writing. The reason may be hardware or software fail, and as a consequence, a file could become partially or completely corrupted, so it'll no longer function properly as its bits shall be scrambled or lacking. An image file, for instance, will no longer present a true image, but a random combination of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etcetera. If this kind of a problem occurs and it's not noticed by the system or by an admin, the data will get corrupted silently and when this happens on a disk drive which is a part of a RAID array where the info is synced between different drives, the corrupted file shall be duplicated on all the other drives and the harm will become long term. Many frequently used file systems either don't have real-time checks or don't have high quality ones which will detect an issue before the damage is done, so silent data corruption is a very common issue on web hosting servers where large amounts of info are stored.

No Data Corruption & Data Integrity in Shared Web Hosting

The integrity of the data which you upload to your new shared web hosting account will be ensured by the ZFS file system that we make use of on our cloud platform. The vast majority of internet hosting suppliers, like our firm, use multiple HDDs to keep content and because the drives work in a RAID, the same information is synchronized between the drives all of the time. In case a file on a drive becomes corrupted for whatever reason, however, it's very likely that it will be copied on the other drives since other file systems don't feature special checks for that. In contrast to them, ZFS uses a digital fingerprint, or a checksum, for every single file. If a file gets corrupted, its checksum won't match what ZFS has as a record for it, and the damaged copy will be replaced with a good one from a different hard disk drive. Since this happens instantly, 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 since all our storage servers use the state-of-the-art ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, so as to verify the integrity of every single file. When you upload content to your account, it will be kept on a couple of redundant drives employed in a RAID i.e. the files shall be the same across all drives. All the copies of a particular file will feature the same checksum on all hard drives and ZFS will compare the checksums of the duplicates right away, and if it discovers a mismatch, which would indicate that one of the copies is damaged, it will substitute that file with a good copy from one of the other disks. Even if there's a sudden blackout, the data on the servers won't become corrupted and there will not be any need for a time-consuming system check which other file systems perform after some malfunction, extending the time needed for the server to go back online. ZFS is the only file system that can really protect your content from silent data corruption.
