Data corruption is the damage of information due to various hardware or software problems. The moment a file gets corrupted, it will no longer work correctly, so an application will not start or will give errors, a text file could be partially or completely unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of data getting harmed without any identification by the system or an administrator, which makes it a serious problem for website hosting servers as failures are much more likely to happen on larger hard disk drives where significant volumes of information are placed. When a drive is part of a RAID and the information on it is replicated on other drives for redundancy, it is very likely that the damaged file will be treated as an ordinary one and it will be copied on all drives, making the damage permanent. A huge number of the file systems which run on web servers these days often are unable to locate corrupted files right away or they need time-consuming system checks through which the server is not working.

No Data Corruption & Data Integrity in Shared Hosting

In case you host your sites in a shared hosting account from our company, you will not have to worry about any of your data ever getting damaged. We can ensure that due to the fact that our cloud hosting platform employs the state-of-the-art ZFS file system. The aforementioned is the only file system that 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 NVMe drives. All the file systems synchronize the files between the different drives with such a setup, but there's no real warranty that a file will not get corrupted. This could happen during the writing process on any drive and afterwards a bad copy may be copied on the rest of the drives. What is different on our platform is that ZFS analyzes the checksums of all files on all of the drives live and in case a corrupted file is located, it is swapped with a good copy with the correct checksum from another drive. In this way, your data will continue to be undamaged no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be protected against silent data corruption as all our storage servers use the reliable ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, to verify the integrity of each file. When you upload content to your account, it will be stored on several redundant drives employed in a RAID i.e. the files shall be the same on all disk drives. All the copies of a specific file will have the same checksum on all hard disks and ZFS will compare the checksums of the duplicates right away, so if it finds a mismatch, which would indicate that one of the copies is damaged, it'll swap that file with a healthy copy from one of the other disks. Even if there's an unexpected power failure, the data on the servers will not become corrupted and there will not be any need for a time-consuming system check which other file systems perform following some malfunction, lengthening the time needed for the server to return online. ZFS is the sole file system that can truly protect your content from silent data corruption.
