Data corruption is the damage of data because of various software or hardware problems. After a file gets corrupted, it will no longer function accurately, so an app will not start or will give errors, a text file can be partially or completely unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of data getting harmed without any acknowledgement by the system or an admin, that makes it a serious problem for hosting servers as failures are much more likely to happen on bigger hard drives where considerable volumes of info are located. In case a drive is a part of a RAID and the information on it is duplicated on other drives for redundancy, it's more than likely that the bad file will be treated as a healthy one and will be copied on all of the drives, making the damage permanent. A huge number of the file systems that run on web servers nowadays often are unable to discover corrupted files right away or they need time-consuming system checks during which the server isn't working.

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. Most internet hosting service providers, like our firm, use multiple HDDs to store content and since the drives work in a RAID, the exact same information is synchronized between the drives all of the time. In case a file on a drive is damaged for reasons unknown, however, it's very likely that it will be duplicated on the other drives since other file systems do not offer special checks for this. In contrast to them, ZFS uses a digital fingerprint, or a checksum, for each file. In the event that a file gets damaged, its checksum won't match what ZFS has as a record for it, so the bad copy will be replaced with a good one from a different hard drive. Since this happens right away, there is no possibility for any of your files to ever get corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Servers

If you obtain one of our semi-dedicated server packages, you will not have to be concerned about silent data corruption as we use ZFS - a high level file system which checks all files in real time. Every 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 number of NVMe drives for redundancy, so if a drive fails, the other ones will take control. 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 another drive. This happens right away, so there will be no danger for any part of your content at any time. By comparison, alternative file systems carry out checks after a system malfunction, but since they don't use anything similar to the checksums that ZFS uses, they can't detect silently corrupted files, so a bad copy can be replicated on the remaining drives as well and you could lose important information. Since this is not the case with ZFS, we're able to guarantee the integrity of every single file you upload no matter what.
