Data corruption is the accidental change of a file or the loss of information which usually occurs during reading or writing. The reason may be hardware or software fail, and consequently, a file can become partially or entirely corrupted, so it'll no longer function correctly as its bits shall be scrambled or missing. An image file, for example, will no longer present an authentic image, but a random mix of colors, an archive will be impossible to unpack as its content will be unreadable, and so on. In the event that such an issue appears 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's a part of a RAID array where the info is synced between various drives, the corrupted file will be copied on all the other drives and the damage will become permanent. Many widespread file systems either do not have 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 rather common issue on web hosting servers where large amounts of data 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 guaranteed by the ZFS file system which we use on our cloud platform. The vast majority of hosting service providers, like our company, use multiple hard disk drives to store content and considering that the drives work in a RAID, identical info is synchronized between the drives all the time. In case a file on a drive becomes damaged for reasons unknown, yet, it's more than likely that it will be duplicated on the other drives as other file systems don't 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 won't match what ZFS has as a record for it, and the damaged copy shall be swapped with a good one from a different drive. Since this happens immediately, there is no possibility for any of your files to ever get damaged.
No Data Corruption & Data Integrity in Semi-dedicated Servers
In case you go for one of our semi-dedicated server
plans, you will not have to worry about silent data corruption as we use ZFS - a high level file system that checks all 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. The file will be synced between a number of SSD drives for redundancy, so if one drive fails, the other ones will take control. ZFS compares the checksum of all of the copies on the different drives and in case it detects a damaged copy, it replaces it with a healthy one from another drive. This is done in real time, so there will be no risk for any part of your content at any moment. In contrast, alternative file systems execute checks only after a system breakdown, but since they do not use anything similar to the checksums that ZFS uses, they cannot detect silently corrupted files, so a bad copy may be replicated on the other drives as well and you could lose crucial data. Because this is not the case with ZFS, we are able to guarantee the integrity of every single file you upload no matter what.
