Data corruption is the damage of info caused by various software or hardware fails. The moment a file gets damaged, it will no longer work properly, so an app will not start or shall give errors, a text file can be partially or fully unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of data getting damaged without any identification by the system or an administrator, that makes it a serious problem for web hosting servers as fails are more likely to happen on larger in size hard disks where considerable volumes of information are stored. If a drive is part of a RAID and the data on it is replicated on other drives for redundancy, it is more than likely that the bad file will be treated as a regular one and it'll be copied on all of the drives, making the damage permanent. A huge number of the file systems which operate on web servers nowadays often are not able to locate corrupted files instantly or they need time-consuming system checks through which the server is not working.

No Data Corruption & Data Integrity in Shared Website Hosting

In case you host your Internet sites in a shared website hosting account from our company, you do not need to worry about your data ever getting corrupted. We can ensure that because our cloud hosting platform works with the revolutionary ZFS file system. The aforementioned is the only file system that uses checksums, or unique digital fingerprints, for each file. All of the info that you upload will be stored in a RAID i.e. simultaneously on multiple SSD drives. All of the file systems synchronize the files between the separate drives with such a setup, but there's no real guarantee that a file will not be corrupted. This may occur throughout the writing process on any drive and after that a bad copy may be copied on all other drives. What is different on our platform is the fact that ZFS compares the checksums of all files on all of the drives instantly and in case a corrupted file is identified, it is substituted with a good copy with the correct checksum from another drive. In this way, your information will continue to be intact no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

You won't have to deal with any kind of silent data corruption issues should you get one of our semi-dedicated hosting plans because the ZFS file system that we use on our cloud hosting platform uses checksums to guarantee that all the files are intact all the time. A checksum is a unique digital fingerprint that is assigned to each and every file saved on a server. Because we store all content on a number of drives at the same time, the same file uses the same checksum on all drives and what ZFS does is that it compares the checksums between the different drives right away. When it detects that a file is corrupted and its checksum is different from what it should be, it replaces that file with a healthy copy without delay, avoiding any chance of the corrupted copy to be synchronized on the rest of the hard drives. ZFS is the sole file system out there that uses checksums, which makes it much more reliable than other file systems that are unable to identify silent data corruption and copy bad files across drives.
