Data corruption is the damage of info caused by various hardware or software failures. The moment a file is corrupted, it will no longer work correctly, so an application will not start or shall give errors, a text file can be partially or completely unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of info getting damaged without any acknowledgement by the system or an admin, which makes it a significant problem for website hosting servers as fails are very likely to happen on bigger hard drives where considerable volumes of information are located. When a drive is a 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 a regular one and will be duplicated on all of the drives, making the harm permanent. A lot of the file systems that run on web servers today often are not able to find corrupted files in real time or they need time-consuming system checks through which the server isn't functioning.
No Data Corruption & Data Integrity in Web Hosting
If you host your Internet sites in a web hosting
account from our company, you will not need to worry about your data ever getting corrupted. We can ensure that since our cloud hosting platform works with the cutting-edge ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for every single file. Any data that you upload will be stored in a RAID i.e. simultaneously on multiple SSDs. All the file systems synchronize the files between the different drives with this type of a setup, but there is no real guarantee that a file won't get corrupted. This could occur at the time of the writing process on any drive and afterwards a bad copy can 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 drives in real time and if a corrupted file is located, it is substituted with a good copy with the correct checksum from some other drive. By doing this, your data will continue to be 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 since all of our storage servers employ the state-of-the-art ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, so as to verify the integrity of each and every file. When you upload content to your account, it will be stored on a couple of redundant drives in a RAID i.e. the files shall be the same across all disks. All the copies of a given file will feature the same checksum on all hard drives and ZFS will compare the checksums of the copies in real time, so if it identifies a mismatch, which would indicate that one of the copies is damaged, it will swap that file with a healthy copy from one of the other drives. Even if there is a sudden blackout, the data on the servers will not become corrupted and there will not be any need for a time-consuming system check that other file systems perform following some malfunction, extending the time needed for the server to return online. ZFS is the sole file system which can really protect your content from silent data corruption.
