Data corruption is the damage of information because of various software or hardware problems. When a file is corrupted, it will no longer work correctly, so an application will not start or shall give errors, a text file will be partially or entirely unreadable, an archive file will be impossible to open and unpack, etc. Silent data corruption is the process of data getting harmed without any identification by the system or an admin, that makes it a serious problem for web hosting servers as fails are very likely to occur on larger in size hard disks where considerable volumes of info are stored. In case a drive is a part of a RAID and the information on it is replicated on other drives for redundancy, it's more than likely that the bad file will be treated as an ordinary one and it will be duplicated on all drives, making the harm permanent. Lots of the file systems which run on web servers these days often are not able to identify corrupted files instantly or they need time-consuming system checks during which the server isn't working.

No Data Corruption & Data Integrity in Shared Hosting

If you host your Internet sites in a shared hosting account with our firm, you don't need to worry about your data ever getting corrupted. We can ensure that due to the fact that our cloud hosting platform employs the reliable ZFS file system. The latter is the only file system that works with checksums, or unique digital fingerprints, for every single file. All of the info that you upload will be kept in a RAID i.e. simultaneously on multiple SSD drives. All of the file systems synchronize the files between the separate drives using this type of a setup, but there's no real warranty that a file will not get corrupted. This may occur at the time of the writing process on each drive and afterwards a damaged copy can be copied on the rest of the 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 located, it's swapped with a good copy with the correct checksum from another drive. In this way, your data will stay intact no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We have avoided any possibility of files getting damaged silently due to the fact that the servers where your semi-dedicated hosting account will be created employ a powerful file system known as ZFS. Its advantage over other file systems is that it uses a unique checksum for each and every file - a digital fingerprint that is checked in real time. As we save all content on multiple 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 stored. In case there is a mismatch, the corrupted copy is replaced with a good one from one of the other drives and since it happens instantly, there's no chance that a damaged copy could remain on our website hosting servers or that it can be duplicated to the other drives in the RAID. None of the other file systems employ this kind of checks and what is more, even during a file system check right after a sudden power failure, none of them can identify silently corrupted files. In contrast, ZFS doesn't crash after a blackout and the regular checksum monitoring makes a time-consuming file system check obsolete.
