Data corruption is the accidental transformation of a file or the loss of info which 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 function as it should since its bits will be scrambled or lost. An image file, for example, will no longer show an actual image, but a random mix of colors, an archive will be impossible to unpack since its content will be unreadable, and so on. If such a problem occurs and it's not noticed by the system or by an administrator, the data will be corrupted silently and in case this happens on a disk drive that's a part of a RAID array where the information is synchronized between various drives, the corrupted file shall be reproduced on all other drives and the damage will be permanent. A large number of popular file systems either don't have real-time checks or do not have good ones which will detect an issue before the damage is done, so silent data corruption is a very common problem on internet hosting servers where large volumes of information are kept.

No Data Corruption & Data Integrity in Cloud Web Hosting

The integrity of the data which you upload to your new cloud web hosting account shall be ensured by the ZFS file system which we work with on our cloud platform. Most internet hosting service providers, like our company, use multiple HDDs to store content and considering that 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 corrupted for some reason, yet, it is very likely that it will be copied on the other drives as alternative file systems do not feature special checks for that. Unlike them, ZFS employs a digital fingerprint, or a checksum, for each file. In the event that a file gets corrupted, its checksum will not match what ZFS has as a record for it, therefore the damaged copy shall be swapped with a good one from another drive. Since this happens in real time, there's no risk 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 shielded from silent data corruption since all of our storage servers make use of the innovative ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, to guarantee the integrity of each and every file. When you upload content to your account, it'll be saved on a couple of redundant drives employed in a RAID i.e. the files will be the same across all disk drives. All of the copies of a given file will have the same checksum on all hard disks and ZFS will compare the checksums of the duplicates right away, so if it registers a mismatch, which would indicate that one of the copies is damaged, it will swap that file with a good copy from one of the other drives. Even if there's an unexpected power loss, the data on the servers won't get corrupted and there won't be any need for a time-consuming system check that other file systems perform following some breakdown, prolonging the time needed for the server to get back online. ZFS is the only file system which can really protect your content from silent data corruption.
