Data corruption is the damage of data because of various software or hardware problems. The moment a file gets damaged, it will no longer work accurately, so an application will not start or shall give errors, a text file will be partially or fully unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of data getting damaged without any identification by the system or an admin, that makes it a significant problem for web hosting servers as failures are more likely to happen on bigger hard drives where vast volumes of information 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 is very likely that the bad file will be treated as a good one and it will be copied on all of the drives, making the harm permanent. A huge number of the file systems which run on web servers these days often are unable to locate corrupted files immediately or they need time-consuming system checks during which the server isn't functioning.

No Data Corruption & Data Integrity in Cloud Hosting

If you host your sites in a cloud hosting account from our company, you don't need to worry about your data ever getting corrupted. We can ensure that due to the fact that our cloud hosting platform works with the state-of-the-art ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for each and every file. Any kind of info that you upload will be kept in a RAID i.e. simultaneously on multiple SSD drives. Many file systems synchronize the files between the different drives using this kind of a setup, but there is no real warranty that a file won't get corrupted. This may happen during the writing process on each drive and after that a bad copy can be copied on all other drives. What is different on our platform is the fact that ZFS analyzes the checksums of all files on all of the drives live and when a corrupted file is identified, it is replaced with a good copy with the correct checksum from another drive. That way, your info will remain unharmed no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You will not have to deal with any kind of silent data corruption issues in case you purchase one of our semi-dedicated server plans because the ZFS file system that we take advantage of on our cloud hosting platform uses checksums in order to guarantee that all the files are intact all the time. A checksum is a unique digital fingerprint which is assigned to each and every file saved on a server. Due to the fact that 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. If 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 without delay, avoiding any possibility of the bad copy to be synchronized on the remaining hard drives. ZFS is the only file system you will find that uses checksums, which makes it far superior to other file systems that are unable to detect silent data corruption and duplicate bad files across hard drives.
