Data corruption is the damage of information due to various software or hardware problems. Once a file gets corrupted, it will no longer function as it should, so an app will not start or shall give errors, a text file can be partially or fully unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of information getting damaged without any acknowledgement by the system or an admin, which makes it a significant problem for hosting servers as failures are more likely to happen on larger hard disks where substantial volumes of info are located. In case 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 healthy one and it will be duplicated on all drives, making the harm permanent. A lot of the file systems which run on web servers today often cannot discover corrupted files in real time or they need time-consuming system checks through which the server is not operational.

No Data Corruption & Data Integrity in Cloud Hosting

In case you host your websites in a cloud hosting account with our company, you do not need to worry about any of your data ever getting damaged. We can ensure that as our cloud hosting platform employs the outstanding ZFS file system. The aforementioned is the only file system that uses checksums, or unique digital fingerprints, for every single file. All data that you upload will be saved in a RAID i.e. simultaneously on multiple NVMes. All the file systems synchronize the files between the different drives with this kind of a setup, but there is no real guarantee that a file will not be corrupted. This can occur throughout the writing process on each drive and afterwards a corrupted copy may be copied on the other drives. What is different on our platform is that ZFS analyzes the checksums of all files on all drives live and in the event that a corrupted file is located, it is substituted with a good copy with the correct checksum from another drive. In this way, your information 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 since all our storage servers use the advanced ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, to ensure the integrity of each file. When you upload content to your account, it will be kept on a couple of redundant drives working in a RAID i.e. the files will be the same across all disk drives. All copies of a given file will feature the same checksum on all hard disks and ZFS will compare the checksums of the copies right away, so if it registers 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 drives. Even if there is an unforeseen power loss, 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 following some failure, prolonging 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.
