Data corruption is the unintended change of a file or the losing of information that often occurs during reading or writing. The reason may be hardware or software fail, and due to this fact, a file may become partially or entirely corrupted, so it will no longer function properly because its bits shall be scrambled or lacking. An image file, for instance, will no longer show a true 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 identified by the system or by an administrator, the data will get corrupted silently and if this happens on a disk drive that is part of a RAID array where the information is synced between different drives, the corrupted file will be reproduced on all other drives and the damage will be long term. Many commonly used file systems either do not feature real-time checks or do not have good ones which can detect an issue before the damage is done, so silent data corruption is a common problem on hosting servers where substantial volumes of data are kept.

No Data Corruption & Data Integrity in Cloud Web Hosting

The integrity of the data which you upload to your new cloud web hosting account will be ensured by the ZFS file system that we take advantage of on our cloud platform. Most of the hosting suppliers, like our firm, use multiple hard disks to keep content and considering that the drives work in a RAID, exactly the same information is synchronized between the drives all the time. If a file on a drive is damaged for some reason, yet, it is likely that it will be copied on the other drives since alternative file systems don't offer special checks for this. In contrast to them, ZFS employs a digital fingerprint, or a checksum, for every single file. In case a file gets damaged, its checksum will not 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 disk drive. Due to the fact that this happens instantly, there is no risk for any of your files to ever get damaged.

No Data Corruption & Data Integrity in Semi-dedicated Servers

In case you obtain one of our semi-dedicated server packages, you will not have to worry about silent file corruption because we use ZFS - an advanced file system that keeps track of all of the files in real time. Every time you upload a file to your hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synchronized between multiple SSD drives for redundancy, so if a drive fails, the other ones will take control. ZFS compares the checksum of all copies on the different drives and if it detects a corrupted copy, it replaces it with a healthy one from a different drive. This happens right away, 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 after a system failure, but since they do not use anything similar to the checksums that ZFS uses, they can't detect silently corrupted files, so a corrupted copy may be replicated on the rest of the drives as well and you can lose crucial info. Since this is not the case with ZFS, we are able to guarantee the integrity of each and every file you upload no matter what.
