Data corruption is the damage of data caused by various hardware or software failures. The moment a file is damaged, it will no longer work as it should, so an app will not start or will give errors, a text file shall be partially or completely unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of information getting harmed without any acknowledgement by the system or an admin, which makes it a serious problem for hosting servers as fails are very likely to occur on larger in size hard disk drives where considerable volumes of info are located. In case a drive is part of a RAID and the data on it is replicated on other drives for redundancy, it is very likely that the bad file will be treated as an undamaged one and will be duplicated on all of the drives, making the damage permanent. Lots of the file systems which run on web servers these days often cannot find corrupted files immediately or they need time-consuming system checks during which the server is not operational.

No Data Corruption & Data Integrity in Shared Hosting

The integrity of the data which you upload to your new shared hosting account shall be guaranteed by the ZFS file system which we work with on our cloud platform. Most of the hosting service providers, including our firm, use multiple hard disks to keep content and since the drives work in a RAID, exactly the same data is synchronized between the drives all the time. If a file on a drive is corrupted for whatever reason, however, it's very likely that it will be copied on the other drives since alternative file systems do not have special checks for this. Unlike them, ZFS employs a digital fingerprint, or a checksum, for every single file. In case a file gets corrupted, its checksum will not match what ZFS has as a record for it, therefore the damaged copy will be substituted with a good one from a different drive. Due to the fact that this happens immediately, there is no risk for any of your files to ever be damaged.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You won't have to deal with any silent data corruption issues whatsoever should you purchase one of our semi-dedicated server solutions due to the fact that the ZFS file system that we employ on our cloud hosting platform uses checksums to ensure that all of your files are undamaged all the time. A checksum is a unique digital fingerprint which is assigned to each and every file saved on a server. Because we store all content on multiple drives simultaneously, the same file uses the same checksum on all of the drives and what ZFS does is that it compares the checksums between the different drives in real time. When it detects that a file is corrupted and its checksum is different from what it has to be, it replaces that file with a healthy copy right away, avoiding any chance of the bad copy to be synchronized on the other hard drives. ZFS is the only file system you will find which uses checksums, which makes it far superior to other file systems which are unable to detect silent data corruption and copy bad files across drives.
