Data corruption is the accidental modification of a file or the loss of information which often occurs during reading or writing. The reason can be hardware or software failure, and due to this fact, a file can become partially or entirely corrupted, so it'll no longer work correctly since its bits shall be scrambled or lost. An image file, for instance, will no longer present 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. If this kind of a problem occurs and it's not identified by the system or by an admin, the data will become corrupted silently and in case this happens on a disk drive that's a part of a RAID array where the data is synced between various different drives, the corrupted file shall be duplicated on all of the other drives and the harm will become long term. A large number of commonly used file systems either don't offer real-time checks or do not have high quality ones which will detect a problem before the damage is done, so silent data corruption is a very common problem on web hosting servers where huge volumes of data are kept.
No Data Corruption & Data Integrity in Shared Hosting
The integrity of the data which you upload to your new shared hosting
account will be ensured by the ZFS file system that we work with on our cloud platform. The vast majority of hosting providers, including our company, use multiple hard disks to store content and because the drives work in a RAID, the exact same information is synchronized between the drives at all times. In case a file on a drive gets damaged for some reason, however, it's likely that it will be copied on the other drives since alternative file systems don't include special checks for this. In contrast to them, ZFS applies 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, and the damaged copy will be replaced with a good one from a different drive. Because this happens in real time, there's no risk for any of your files to ever be corrupted.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
Your semi-dedicated hosting
account will be resistant to silent data corruption since all our storage servers use the innovative ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, in order to verify the integrity of each and every file. When you upload content to your account, it will be saved on several redundant drives employed in a RAID i.e. the files will be the same across all drives. All of the copies of a given file will have the same checksum on all hard drives and ZFS will compare the checksums of the copies in real time, so 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 drives. Even if there's a sudden power loss, 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 following some malfunction, lengthening the time needed for the server to go back online. ZFS is the file system which can truly protect your content from silent data corruption.
