Data corruption is the damage of information due to various software or hardware failures. When a file is corrupted, it will no longer function properly, so an application will not start or will give errors, a text file can be partially or entirely unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of information getting harmed without any acknowledgement by the system or an admin, that makes it a significant problem for website hosting servers as failures are much more likely to occur on larger in size hard disk drives where significant volumes of info are located. When a drive is a part of a RAID and the information on it is copied on other drives for redundancy, it's more than likely that the bad file will be treated as a healthy one and it'll be copied on all drives, making the harm permanent. A huge number of the file systems which run on web servers nowadays often are unable to locate corrupted files in real time or they need time-consuming system checks during which the server is not functioning.

No Data Corruption & Data Integrity in Hosting

If you host your sites in a hosting account with our company, you don't need to worry about your data ever getting corrupted. We can ensure that due to the fact that our cloud hosting platform employs the advanced ZFS file system. The latter is the only file system that uses checksums, or unique digital fingerprints, for each file. All of the information that you upload will be kept in a RAID i.e. simultaneously on many different NVMes. All the file systems synchronize the files between the different drives with this type of a setup, but there's no real guarantee that a file won't get corrupted. This could occur throughout the writing process on any drive and then a corrupted copy can be copied on the rest of the drives. What makes the difference on our platform is the fact that ZFS compares the checksums of all files on all the drives in real time and in case a corrupted file is discovered, it's replaced with a good copy with the correct checksum from some other 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

If you get one of our semi-dedicated server solutions, you won't need to worry about silent data corruption since we use ZFS - an advanced file system that monitors all files in real time. Whenever you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synchronized between multiple NVMe drives for redundancy, so if a drive fails, the other ones will take over. ZFS compares the checksum of all of the copies on the different drives and when it detects a damaged copy, it replaces it with a healthy one from another drive. This happens instantly, so there will be no threat for any part of your content at any time. In comparison, all the other file systems execute checks only after a system malfunction, but since they don't use anything similar to the checksums that ZFS uses, they can't detect silently corrupted files, so a bad copy may be replicated on the rest of the disks as well and you can lose important information. Because this is not the case with ZFS, we can guarantee the integrity of each and every file you upload no matter what.
