Data corruption is the damage of data due to various software or hardware problems. Once a file is damaged, it will no longer function properly, so an application will not start or shall give errors, a text file could be partially or fully unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of information getting harmed without any acknowledgement by the system or an admin, which makes it a serious problem for website hosting servers as fails are much more likely to happen on larger in size hard disks where significant volumes of information are stored. In case a drive is part of a RAID and the info on it is copied on other drives for redundancy, it's likely that the bad file will be treated as an ordinary one and it will be duplicated on all the drives, making the damage permanent. A lot of the file systems which operate on web servers these days often cannot identify corrupted files in real time or they need time-consuming system checks during which the server isn't working.

No Data Corruption & Data Integrity in Shared Web Hosting

In case you host your sites in a shared web hosting account with our firm, you will not have to worry about any of your data ever getting corrupted. We can guarantee that due to the fact that our cloud hosting platform employs the leading-edge ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for every single file. Any kind of information that you upload will be saved in a RAID i.e. simultaneously on a large number of SSDs. Many file systems synchronize the files between the separate drives with 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 each drive and afterwards a damaged copy may be copied on the rest of the drives. What is different on our platform is that ZFS analyzes the checksums of all files on all the drives live and when a corrupted file is located, it's replaced with a good copy with the correct checksum from some other drive. By doing this, your info will continue to be undamaged no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We have avoided any chance of files getting damaged silently as the servers where your semi-dedicated hosting account will be created take advantage of a powerful file system named ZFS. Its advantage over other file systems is that it uses a unique checksum for each file - a digital fingerprint that's checked in real time. As we keep all content on numerous SSD drives, ZFS checks whether the fingerprint of a file on one drive matches the one on the remaining drives and the one it has saved. When there is a mismatch, the bad copy is replaced with a healthy one from one of the other drives and because this happens instantly, there is no chance that a damaged copy could remain on our servers or that it could be duplicated to the other hard drives in the RAID. None of the other file systems work with such checks and in addition, even during a file system check following a sudden blackout, none of them can detect silently corrupted files. In comparison, ZFS does not crash after a blackout and the constant checksum monitoring makes a time-consuming file system check unneeded.
