Data corruption is the damage of info caused by various software or hardware fails. After a file gets corrupted, it will no longer work properly, so an application will not start or shall give errors, a text file could be partially or fully unreadable, an archive file 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 significant problem for web hosting servers as problems are more likely to occur on larger hard disks where considerable volumes of information are located. When a drive is part of a RAID and the info on it is replicated on other drives for redundancy, it is very likely that the damaged file will be treated as a standard one and it will be duplicated on all of the drives, making the harm permanent. Lots of the file systems which run on web servers these days often are not able to discover corrupted files instantly or they need time-consuming system checks through which the server isn't operational.

No Data Corruption & Data Integrity in Hosting

The integrity of the data which you upload to your new hosting account shall be guaranteed by the ZFS file system that we employ on our cloud platform. The vast majority of web hosting service providers, like our company, use multiple hard drives to store content and considering that the drives work in a RAID, the same info is synchronized between the drives at all times. In case a file on a drive gets damaged for whatever reason, however, it is likely that it will be duplicated on the other drives since other file systems don't offer special checks for this. In contrast to them, ZFS applies 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 damaged copy will be replaced with a good one from another drive. Because this happens in real time, there is no possibility for any of your files to ever be damaged.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

If you acquire one of our semi-dedicated hosting plans, you will not have to be concerned about silent data 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 account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synchronized between several SSD drives for redundancy, so if a drive fails, the other ones will take over. ZFS compares the checksum of all the copies on the different drives and if it detects a corrupted copy, it replaces it with a healthy one from another drive. This is done immediately, so there will be no risk for any part of your content at any moment. In comparison, all the other file systems perform checks after a system breakdown, but since they don't 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 may lose precious info. As this isn't the case with ZFS, we are able to guarantee the integrity of each file you upload no matter what.
