Data corruption is the unintended transformation of a file or the losing of information that usually occurs during reading or writing. The reason may be hardware or software malfunction, and as a result, a file could become partially or entirely corrupted, so it'll no longer function correctly since its bits shall be scrambled or lacking. An image file, for example, will no longer display a real image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, etcetera. In case this kind of an issue occurs and it isn't found by the system or by an admin, the data will be corrupted silently and when this happens on a disk drive that is part of a RAID array where the info is synced between various drives, the corrupted file shall be duplicated on all the other drives and the harm will be permanent. A number of popular file systems either don't have real-time checks or don't have good ones that can detect an issue before the damage is done, so silent data corruption is a rather common issue on internet hosting servers where huge volumes of information are stored.

No Data Corruption & Data Integrity in Cloud Hosting

The integrity of the data that you upload to your new cloud hosting account shall be ensured by the ZFS file system which we employ on our cloud platform. Most hosting service providers, like our firm, use multiple hard disks to store content and considering that the drives work in a RAID, the same data is synchronized between the drives all the time. When a file on a drive is corrupted for some reason, yet, it is likely that it will be reproduced on the other drives since alternative file systems don't have special checks for that. Unlike them, ZFS works with a digital fingerprint, or a checksum, for every file. In the event that a file gets corrupted, its checksum will not match what ZFS has as a record for it, so the damaged copy shall be substituted with a good one from a different hard disk. Since this happens right away, there is no risk for any of your files to ever be damaged.

No Data Corruption & Data Integrity in Semi-dedicated Servers

If you buy one of our semi-dedicated server packages, you won't have to worry about silent data corruption as we use ZFS - a high level file system that monitors all of the files in real time. Whenever you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synced between several 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 when it detects a corrupted copy, it replaces it with a healthy one from a different drive. This happens immediately, so there will be no risk for any part of your content at any time. By comparison, other file systems carry out checks only after a system malfunction, but since they do not use anything similar to the checksums which ZFS uses, they are unable to detect silently corrupted files, so a bad copy could be replicated on the remaining disks as well and you could lose crucial information. Since this isn't the case with ZFS, we're able to warrant the integrity of each and every file you upload no matter what.
