Data corruption is the damage of info due to various software or hardware fails. Once a file gets 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 file will be impossible to open and then 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 serious problem for web hosting servers as problems are very likely to happen on larger hard disks where significant volumes of information are placed. If a drive is part of a RAID and the information on it is copied on other drives for redundancy, it is likely that the damaged file will be treated as an undamaged one and it'll be duplicated on all of the drives, making the harm permanent. A huge number of the file systems which run on web servers nowadays often are unable to detect corrupted files immediately or they need time-consuming system checks during which the server isn't operational.
No Data Corruption & Data Integrity in Cloud Hosting
If you host your Internet sites in a cloud hosting
account with our company, you do not have to worry about any of your data ever getting damaged. We can guarantee that as our cloud hosting platform works with the outstanding ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for each file. All of the information that you upload will be kept in a RAID i.e. simultaneously on a number of SSDs. All file systems synchronize the files between the different drives using this kind of a setup, but there is no real guarantee that a file will not get corrupted. This could occur during the writing process on any drive and then a damaged copy can be copied on the rest of the drives. What makes the difference on our platform is the fact that ZFS analyzes the checksums of all files on all the drives instantly and in the event that a corrupted file is identified, it is substituted with a good copy with the correct checksum from some other drive. By doing this, your information will remain unharmed no matter what, even if an entire drive fails.
