Data corruption is the damage of info caused by various hardware or software problems. The moment a file is corrupted, it will no longer function correctly, so an app will not start or will give errors, a text file could be partially or entirely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of data getting damaged without any acknowledgement by the system or an administrator, that makes it a significant problem for web hosting servers as fails are more likely to happen on bigger hard disks where large volumes of info are placed. When a drive is part of a RAID and the data on it is duplicated on other drives for redundancy, it's likely that the damaged file will be treated as a good one and it'll be copied on all 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 in real time or they need time-consuming system checks during which the server isn't operational.

No Data Corruption & Data Integrity in Shared Hosting

In case you host your websites in a shared hosting account with our company, you do not need to worry about your data ever getting corrupted. We can ensure that because our cloud hosting platform uses the outstanding ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for every single file. All the data that you upload will be saved in a RAID i.e. simultaneously on many different NVMe drives. All file systems synchronize the files between the separate drives with this kind of a setup, but there's no real warranty that a file won't get corrupted. This may occur throughout the writing process on any drive and then a corrupted copy may be copied on all other drives. What is different on our platform is the fact that ZFS compares the checksums of all files on all of the drives live and if a corrupted file is found, it is swapped with a good copy with the correct checksum from another drive. This way, your data will remain intact no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be protected against silent data corruption as all our storage servers work with the efficient ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, so as to ensure the integrity of every single file. When you upload content to your account, it will be stored on several redundant drives employed in a RAID i.e. the files will be the same across all drives. All copies of a given file will have the same checksum on all drives and ZFS will compare the checksums of the copies quickly, and if it registers a mismatch, which will indicate that one of the copies is damaged, it'll substitute that file with a healthy copy from one of the other drives. Even if there's an unexpected power failure, the data on the servers won't get corrupted and there will not be any need for a time-consuming system check which other file systems perform after some failure, 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.
