Data corruption is the damage of data caused by various hardware or software problems. When a file is corrupted, it will no longer work accurately, so an app will not start or shall give errors, a text file can 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 identification by the system or an admin, that makes it a serious problem for website hosting servers as failures are very likely to occur on larger hard drives where significant volumes of information are located. 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 a standard one and it will be duplicated on all the drives, making the damage permanent. A huge number of the file systems that operate on web servers these days often are not able to detect corrupted files right away or they need time-consuming system checks through which the server isn't functioning.

No Data Corruption & Data Integrity in Cloud Hosting

If you host your sites in a cloud hosting account from our firm, you won't have to worry about your data ever getting damaged. We can guarantee that since our cloud hosting platform employs the revolutionary ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for each file. Any info that you upload will be stored in a RAID i.e. simultaneously on many different SSD drives. Many file systems synchronize the files between the separate drives using this kind of a setup, but there's no real warranty that a file will not be corrupted. This could happen during the writing process on any drive and then a bad copy may be copied on the rest of the drives. What makes the difference on our platform is that ZFS analyzes the checksums of all files on all the drives in real time and in the event that a corrupted file is identified, it is swapped with a good copy with the correct checksum from some other drive. This way, your data will remain unharmed no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be shielded from silent data corruption because all of our storage servers employ the state-of-the-art ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, so as to verify the integrity of every single file. When you upload content to your account, it'll be kept on a couple of redundant drives in a RAID i.e. the files will be the same across all disk drives. All copies of a specific file will feature the same checksum on all hard drives and ZFS will compare the checksums of the duplicates right away, and if it discovers a mismatch, that will indicate that one of the copies is damaged, it will substitute that file with a good copy from one of the other disks. Even if there's a sudden blackout, the data on the servers will not be corrupted and there won't be any need for a time-consuming system check that other file systems perform following some breakdown, prolonging the time needed for the server to go back online. ZFS is the only file system which can truly protect your content from silent data corruption.
