Data corruption is the unintended transformation of a file or the losing of info that usually occurs during reading or writing. The reason can be hardware or software fail, and consequently, a file could become partially or completely corrupted, so it will no longer work properly because its bits will be scrambled or missing. An image file, for instance, will no longer show an accurate image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, etcetera. When such a problem occurs and it is not noticed by the system or by an administrator, the data will get 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 will be replicated on all other drives and the damage will become permanent. Many widely used file systems either don't have real-time checks or don't have good ones which can detect a problem before the damage is done, so silent data corruption is a very common issue on internet hosting servers where huge volumes of info are stored.

No Data Corruption & Data Integrity in Cloud Hosting

The integrity of the data which you upload to your new cloud hosting account shall be ensured by the ZFS file system which we make use of on our cloud platform. Most of the internet hosting providers, like our firm, use multiple hard drives to store content and considering that the drives work in a RAID, the same data is synchronized between the drives all of the time. In case a file on a drive gets corrupted for whatever reason, however, it's likely that it will be copied on the other drives because alternative file systems don't feature special checks for that. Unlike them, ZFS works with a digital fingerprint, or a checksum, for each and every file. In the event that a file gets corrupted, its checksum will not match what ZFS has as a record for it, which means that the bad copy will be substituted with a good one from a different hard drive. Because this happens in real time, there is no risk for any of your files to ever be damaged.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

If you obtain one of our semi-dedicated hosting packages, you will not need to be concerned about silent file corruption since we use ZFS - a high level file system which keeps track of all of the files in real time. Each time you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synced between multiple SSD drives for redundancy, so if one drive fails, the other ones will take over. ZFS compares the checksum of all copies on the different drives and in case it detects a damaged 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 moment. In comparison, all of the other file systems perform checks only after a system failure, but since they do not use anything similar to the checksums which ZFS uses, they will not detect silently corrupted files, so a bad copy may be replicated on the rest of the disks as well and you can lose crucial info. Because this is not the case with ZFS, we can warrant the integrity of each file you upload no matter what.
