Data corruption is the damage of info because of various hardware or software failures. When a file is corrupted, it will no longer function correctly, so an app will not start or will give errors, a text file could 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 harmed without any acknowledgement by the system or an admin, that makes it a serious problem for hosting servers as fails are much more likely to happen on larger hard disk drives where substantial volumes of info are kept. In case a drive is part of a RAID and the data on it is duplicated on other drives for redundancy, it's very likely that the bad file will be treated as a regular one and will be copied on all the drives, making the harm permanent. Lots of the file systems which run on web servers nowadays often cannot locate corrupted files immediately or they need time-consuming system checks during which the server is not functioning.
No Data Corruption & Data Integrity in Cloud Web Hosting
If you host your sites in a cloud web hosting
account with our company, you don't need to worry about your data ever getting damaged. We can ensure that since our cloud hosting platform works with the reliable ZFS file system. The aforementioned is the only file system that uses checksums, or unique digital fingerprints, for each and every file. Any kind of data that you upload will be saved in a RAID i.e. simultaneously on numerous SSD drives. A lot of file systems synchronize the files between the separate drives using this type of a setup, but there is no real warranty that a file will not be corrupted. This may happen throughout the writing process on any drive and then a damaged copy can be copied on all other drives. What makes the difference on our platform is that ZFS analyzes the checksums of all files on all the drives instantly and in the event that a corrupted file is located, it is substituted with a good copy with the correct checksum from some other drive. That way, your data will remain intact no matter what, even if a whole drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
Your semi-dedicated hosting
account will be shielded from silent data corruption since all of our storage servers use the reliable ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, to ensure the integrity of each file. When you upload content to your account, it will be saved on several redundant drives operating in a RAID i.e. the files will be the same across all disk drives. All the copies of a given file will feature the same checksum on all hard disks and ZFS will compare the checksums of the copies quickly, and if it registers a mismatch, that would indicate that one of the copies is damaged, it will swap that file with a good copy from one of the other drives. Even if there's an unforeseen power failure, the data on the servers will not get corrupted and there won't be any need for a time-consuming system check that other file systems perform following some breakdown, extending the time needed for the server to go back online. ZFS is the file system which can really protect your content from silent data corruption.
