Data corruption is the unintentional modification of a file or the loss of info which usually occurs during reading or writing. The reason may be hardware or software malfunction, and for that reason, a file can become partially or completely corrupted, so it will no longer function as it should since its bits will be scrambled or lacking. An image file, for example, will no longer display an accurate image, but a random mix of colors, an archive will be impossible to unpack since its content will be unreadable, etcetera. If this kind of an issue appears and it's not found by the system or by an administrator, the data will get corrupted silently and if this happens on a drive which is part of a RAID array where the information is synchronized between different drives, the corrupted file will be copied on all other drives and the damage will become permanent. A number of popular file systems either don't have 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 rather common matter on hosting servers where large amounts of data are stored.

No Data Corruption & Data Integrity in Website Hosting

The integrity of the data which you upload to your new website hosting account shall be ensured by the ZFS file system that we make use of on our cloud platform. The vast majority of hosting providers, like our company, use multiple hard drives to store content and since the drives work in a RAID, the same info is synchronized between the drives all of the time. When a file on a drive is damaged for some reason, however, it's very likely that it will be duplicated on the other drives since other file systems do not feature special checks for this. In contrast to them, ZFS uses a digital fingerprint, or a checksum, for each file. In case a file gets damaged, its checksum won't match what ZFS has as a record for it, which means that the damaged copy will be replaced with a good one from a different hard drive. Due to the fact that this happens right away, there's 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 will not have to worry about silent data corruption because we use ZFS - an advanced file system that keeps track of all 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. This file will be synchronized 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 the copies on the different drives and in case it detects a corrupted copy, it replaces it with a healthy one from a different drive. This is done right away, so there will be no risk for any part of your content at any moment. In contrast, other file systems carry out checks only after a system failure, but since they don't use anything similar to the checksums that ZFS uses, they are unable to detect silently corrupted files, so a bad copy can be replicated on the remaining disks as well and you could lose precious info. Because this isn't the case with ZFS, we can guarantee the integrity of each and every file you upload no matter what.
