Data corruption is the damage of info because of various hardware or software fails. When a file gets damaged, it will no longer function accurately, so an app will not start or shall give errors, a text file could be partially or entirely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of data getting damaged without any acknowledgement by the system or an administrator, which makes it a serious problem for hosting servers as failures are very likely to happen on bigger hard disk drives where large volumes of information are kept. When a drive is part of a RAID and the data on it is duplicated on other drives for redundancy, it's likely that the bad file will be treated as a healthy one and it'll be copied on all drives, making the harm permanent. Lots of the file systems that operate on web servers today often are not able to find corrupted files in real time or they need time-consuming system checks during which the server isn't functioning.
No Data Corruption & Data Integrity in Web Hosting
In case you host your Internet sites in a web hosting
account with our firm, you don't need to worry about your data ever getting damaged. We can guarantee that as our cloud hosting platform works with the cutting-edge ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for each file. Any kind of data that you upload will be kept in a RAID i.e. simultaneously on numerous SSDs. All the file systems synchronize the files between the separate drives using such a setup, but there is no real warranty that a file won't be corrupted. This could occur at the time of the writing process on any drive and after that a bad copy can be copied on the other drives. What is different on our platform is the fact that ZFS analyzes the checksums of all files on all the drives live and when a corrupted file is located, it is swapped with a good copy with the correct checksum from another drive. That way, your data will continue to be unharmed no matter what, even if a whole drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Servers
You will not experience any silent data corruption issues whatsoever should you get one of our semi-dedicated server
packages as the ZFS file system that we use on our cloud hosting platform uses checksums to ensure that all files are intact at all times. A checksum is a unique digital fingerprint that is given to each and every file saved on a server. Since we store all content on multiple 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. If 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 right away, avoiding any chance of the corrupted copy to be synchronized on the rest of the hard disks. ZFS is the sole file system on the market that uses checksums, which makes it much more dependable than other file systems that cannot detect silent data corruption and copy bad files across hard drives.
