Data corruption is the damage of data caused by various hardware or software failures. The moment a file gets corrupted, it will no longer function properly, so an app 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 information getting damaged without any identification by the system or an administrator, which makes it a significant problem for hosting servers as fails are very likely to happen on bigger hard disks where vast volumes of information are kept. When a drive is part of a RAID and the info on it is duplicated on other drives for redundancy, it is likely that the bad file will be treated as a standard one and it will be duplicated on all of the drives, making the harm permanent. Lots of the file systems that operate on web servers these days often cannot find corrupted files in real time or they need time-consuming system checks during which the server is not operational.

No Data Corruption & Data Integrity in Shared Website Hosting

In case you host your Internet sites in a shared website hosting account from our company, you don't need to worry about any of your data ever getting damaged. We can ensure that because our cloud hosting platform works with the amazing ZFS file system. The latter is the only file system that uses checksums, or unique digital fingerprints, for each file. All info that you upload will be saved in a RAID i.e. simultaneously on a large number of NVMes. A lot of file systems synchronize the files between the separate drives with such a setup, but there is no real warranty that a file will not be corrupted. This could happen at the time of the writing process on any drive and afterwards a corrupted copy can be copied on the other drives. What makes the difference on our platform is the fact that ZFS analyzes the checksums of all files on all of the drives instantly and when a corrupted file is discovered, it is replaced with a good copy with the correct checksum from some other drive. This way, your information will stay 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 resistant to silent data corruption since all our storage servers use the innovative ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, to verify the integrity of each file. When you upload content to your account, it'll be placed on a couple of redundant drives in a RAID i.e. the files shall be the same on all disks. All copies of a specific file will have the same checksum on all hard drives and ZFS will compare the checksums of the duplicates in real time, so if it identifies a mismatch, that will indicate that one of the copies is corrupted, it'll substitute that file with a healthy copy from one of the other drives. Even if there's an unexpected power loss, the data on the servers won't get corrupted and there won't 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 file system that can really protect your content from silent data corruption.
