Data corruption is the damage of information due to various software or hardware failures. When a file gets damaged, it will no longer function correctly, so an application will not start or shall give errors, a text file shall be partially or fully 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 admin, that makes it a serious problem for web hosting servers as fails are very likely to happen on bigger hard disks where substantial volumes of info are kept. If a drive is part of a RAID and the information on it is replicated on other drives for redundancy, it's very likely that the bad file will be treated as a good one and it will be copied on all of the drives, making the damage permanent. Lots of the file systems which operate on web servers these days often are unable to detect corrupted files immediately or they need time-consuming system checks through which the server isn't functioning.

No Data Corruption & Data Integrity in Cloud Hosting

In case you host your websites in a cloud hosting account with our firm, 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 outstanding ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for each file. All the data that you upload will be kept in a RAID i.e. simultaneously on multiple NVMes. All file systems synchronize the files between the separate drives with such a setup, but there's no real warranty that a file won't get corrupted. This could occur throughout the writing process on each drive and then a corrupted copy can 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 drives live and when a corrupted file is identified, it is substituted with a good copy with the correct checksum from another drive. That way, your information will remain unharmed 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 resistant to silent data corruption because all our storage servers use the state-of-the-art ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, so as to ensure the integrity of each and every file. When you upload content to your account, it'll be kept on several redundant drives working in a RAID i.e. the files shall be the same across all disks. All of 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, and if it detects a mismatch, that would indicate that one of the copies is damaged, it'll swap that file with a good copy from one of the other disks. Even if there is an unexpected blackout, the data on the servers will not get corrupted and there won't be any need for a time-consuming system check that other file systems perform after 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.
