Data corruption is the accidental modification of a file or the losing of info which often occurs during reading or writing. The reason may be hardware or software failure, and consequently, a file can become partially or fully corrupted, so it'll no longer work correctly since its bits will be scrambled or missing. An image file, for example, will no longer show an authentic image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, etc. When such an issue occurs and it isn't recognized by the system or by an admin, the data will become corrupted silently and if this happens on a disk drive that is a part of a RAID array where the info is synchronized between different drives, the corrupted file shall be duplicated on all of the other drives and the harm will become permanent. Numerous frequently used file systems either don't offer real-time checks or do not have good ones that can detect a problem before the damage is done, so silent data corruption is a very common matter on internet hosting servers where large volumes of data are kept.

No Data Corruption & Data Integrity in Hosting

The integrity of the data which you upload to your new hosting account will be ensured by the ZFS file system which we work with on our cloud platform. The vast majority of internet hosting providers, including our firm, use multiple HDDs to store content and because the drives work in a RAID, the same information is synchronized between the drives all of the time. When a file on a drive becomes damaged for some reason, yet, it's very likely that it will be duplicated on the other drives since other file systems do not include special checks for that. Unlike them, ZFS applies a digital fingerprint, or a checksum, for every single file. In the event that a file gets damaged, its checksum will not match what ZFS has as a record for it, therefore the bad copy shall be swapped with a good one from another hard disk drive. Because this happens instantly, there is no risk for any of your files to ever be corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

In case you purchase one of our semi-dedicated hosting solutions, you won't have to be concerned about silent file corruption because we use ZFS - an advanced file system which keeps track of all files in real time. Every time you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synced between a couple of SSD drives for redundancy, so if one drive fails, the other ones will take over. ZFS compares the checksum of all of the copies on the different drives and if it detects a damaged copy, it replaces it with a healthy one from another drive. This happens immediately, so there will be no threat for any part of your content at any moment. In contrast, alternative file systems carry out checks only after a system breakdown, but since they don't use anything similar to the checksums that ZFS uses, they cannot detect silently corrupted files, so a corrupted copy can be replicated on the other drives as well and you could lose crucial information. Because this isn't the case with ZFS, we can warrant the integrity of each and every file you upload no matter what.
