Data corruption is the damage of information due to various hardware or software failures. After a file gets corrupted, it will no longer function properly, so an application will not start or will give errors, a text file could be partially or fully unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of information getting damaged without any identification by the system or an administrator, that makes it a significant problem for hosting servers as failures are much more likely to occur on larger in size hard drives where considerable volumes of information are located. When a drive is a part of a RAID and the information on it is replicated on other drives for redundancy, it's very likely that the bad file will be treated as a regular one and it will be duplicated on all of the drives, making the damage permanent. A huge number of the file systems that run on web servers today often are unable to detect corrupted files immediately or they need time-consuming system checks during which the server is not functioning.

No Data Corruption & Data Integrity in Cloud Hosting

In case you host your websites in a cloud hosting account with our firm, you don't have to worry about your data ever getting corrupted. We can guarantee that since our cloud hosting platform works with the reliable ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for every single file. All of the data that you upload will be stored in a RAID i.e. simultaneously on many SSD drives. All the file systems synchronize the files between the separate drives using this type of a setup, but there's no real warranty that a file won't get corrupted. This can happen during the writing process on any drive and then a bad copy may be copied on the other drives. What is different on our platform is that ZFS examines the checksums of all files on all the drives right away and in the event that a corrupted file is located, it's swapped with a good copy with the correct checksum from another drive. This way, your info will remain intact no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

If you buy one of our semi-dedicated hosting packages, you will not have to worry about silent file corruption as we use ZFS - an advanced file system which checks all of the files in real time. Each time you upload a file to your web hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The 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 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 immediately, so there will be no threat for any part of your content at any moment. In contrast, other file systems carry out checks only after a system malfunction, but since they do not use anything similar to the checksums that ZFS uses, they are unable to detect silently corrupted files, so a bad copy could be replicated on the remaining drives as well and you could lose critical info. Because this is not the case with ZFS, we are able to guarantee the integrity of every single file you upload no matter what.
