Data corruption is the damage of info due to various hardware or software problems. Once a file is corrupted, it will no longer function as it should, so an app will not start or shall give errors, a text file shall be partially or entirely unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of information getting damaged without any identification by the system or an admin, that makes it a serious problem for web hosting servers as fails are very likely to happen on larger in size hard disk drives where significant volumes of info are kept. In case a drive is part of a RAID and the data on it is copied on other drives for redundancy, it's likely that the damaged file will be treated as a good one and it'll be copied on all drives, making the harm permanent. Lots of the file systems that run on web servers these days often cannot discover corrupted files in real time or they need time-consuming system checks during which the server is not operational.
No Data Corruption & Data Integrity in Cloud Web Hosting
In case you host your Internet sites in a cloud web hosting
account from our company, you do not need to worry about your data ever getting corrupted. We can ensure that as our cloud hosting platform works with the advanced ZFS file system. The aforementioned is the only file system that works with checksums, or unique digital fingerprints, for each file. All data that you upload will be stored in a RAID i.e. simultaneously on numerous SSDs. All of the file systems synchronize the files between the different drives with such a setup, but there's no real guarantee that a file will not get corrupted. This could happen during the writing process on any drive and after that a corrupted copy can be copied on all other drives. What is different on our platform is that ZFS examines the checksums of all files on all drives immediately and in case a corrupted file is identified, it's substituted with a good copy with the correct checksum from some other drive. That way, your data will remain unharmed no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Servers
You will not experience any silent data corruption issues if you acquire one of our semi-dedicated server
packages due to the fact that the ZFS file system that we use on our cloud hosting platform uses checksums in order to ensure that all of your files are intact at all times. A checksum is a unique digital fingerprint that is assigned to each and every file stored on a server. Because we store all content on a number of 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 right away, avoiding any probability of the bad copy to be synchronized on the remaining hard drives. ZFS is the sole file system you can find which uses checksums, which makes it much more dependable than other file systems which are unable to detect silent data corruption and duplicate bad files across hard drives.
