Data corruption is the damage of information because of various software or hardware problems. The moment a file is damaged, it will no longer function properly, so an application will not start or shall give errors, a text file can be partially or completely unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of info getting harmed without any acknowledgement by the system or an administrator, which makes it a significant problem for website hosting servers as failures are more likely to occur on larger hard drives where substantial volumes of information are located. If a drive is a part of a RAID and the data on it is replicated on other drives for redundancy, it is very likely that the damaged file will be treated as a standard one and it will be copied on all drives, making the harm permanent. A huge number of the file systems which run on web servers nowadays often cannot locate corrupted files immediately or they need time-consuming system checks through which the server isn't operational.

No Data Corruption & Data Integrity in Cloud Hosting

If you host your websites in a cloud hosting account with our company, you won't have to worry about any of your data ever getting damaged. We can guarantee that due to the fact that our cloud hosting platform works with the advanced ZFS file system. The latter is the only file system that works with checksums, or unique digital fingerprints, for each and every file. Any information that you upload will be kept in a RAID i.e. simultaneously on numerous SSD drives. All the file systems synchronize the files between the different drives using this kind of a setup, but there's no real warranty that a file will not get corrupted. This may happen during the writing process on each drive and then a bad copy may be copied on all other drives. What makes the difference on our platform is that ZFS analyzes the checksums of all files on all of the drives instantly and if a corrupted file is located, it's replaced with a good copy with the correct checksum from some other drive. That way, your information will stay undamaged no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We have avoided any probability of files getting damaged silently because the servers where your semi-dedicated server account will be created employ a powerful file system known as ZFS. Its advantage over various other file systems is that it uses a unique checksum for every single file - a digital fingerprint that is checked in real time. As we keep all content on numerous SSD drives, ZFS checks if the fingerprint of a file on one drive matches the one on the rest of the drives and the one it has stored. If there's a mismatch, the corrupted copy is replaced with a healthy one from one of the other drives and because it happens instantly, there's no chance that a damaged copy can remain on our servers or that it could be copied to the other drives in the RAID. None of the other file systems employ this kind of checks and what's more, even during a file system check right after a sudden blackout, none of them will detect silently corrupted files. In comparison, ZFS will not crash after a power loss and the constant checksum monitoring makes a lenghty file system check unneeded.
