Data corruption is the damage of data because of various hardware or software failures. After a file gets corrupted, it will no longer function properly, so an application will not start or will give errors, a text file could be partially or completely unreadable, an archive will be impossible to open and then 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 website hosting servers as problems are more likely to happen on larger in size hard disk drives where large volumes of info are located. In case 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 an ordinary one and it will be copied on all the drives, making the damage permanent. A huge number of the file systems which run on web servers these days often cannot detect corrupted files right away or they need time-consuming system checks through which the server is not operational.
No Data Corruption & Data Integrity in Cloud Website Hosting
In case you host your sites in a cloud website hosting account from our company, you won't need to worry about any of your data ever getting damaged. We can ensure that because our cloud hosting platform works with the reliable ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for every single file. All data that you upload will be stored in a RAID i.e. simultaneously on a large number of NVMe drives. Many 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 get corrupted. This can occur at the time of the writing process on any drive and after that a bad copy may be copied on all other drives. What makes the difference on our platform is the fact that ZFS compares the checksums of all files on all the drives in real time and in the event that a corrupted file is found, it is substituted with a good copy with the correct checksum from some other drive. By doing this, your information will stay 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 protected against silent data corruption as all our storage servers use the efficient ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, in order to guarantee the integrity of each and every file. When you upload content to your account, it'll be saved on several redundant drives in a RAID i.e. the files shall be the same on all drives. All the copies of a specific file will feature the same checksum on all drives and ZFS will compare the checksums of the copies in real time, and if it discovers a mismatch, which would indicate that one of the copies is damaged, it will substitute that file with a healthy copy from one of the other drives. Even if there's a sudden power loss, the data on the servers won't become corrupted and there will not be any need for a time-consuming system check which other file systems perform after some malfunction, extending the time needed for the server to return online. ZFS is the only file system which can really protect your content from silent data corruption.
