Data corruption is the damage of information because of various hardware or software problems. When a file gets corrupted, it will no longer function correctly, so an app will not start or shall give errors, a text file could 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 harmed without any acknowledgement by the system or an admin, which makes it a significant problem for website hosting servers as fails are much more likely to occur on larger hard disks where significant volumes of information are kept. In case a drive is a part of a RAID and the information on it is duplicated on other drives for redundancy, it's very likely that the damaged file will be treated as a healthy one and it will be copied on all of the drives, making the damage permanent. A huge number of the file systems which operate on web servers today often cannot identify corrupted files right away or they need time-consuming system checks through which the server is not operational.

No Data Corruption & Data Integrity in Shared Hosting

In case you host your Internet sites in a shared hosting account from our company, you will not need to worry about any of your data ever getting damaged. We can ensure that as our cloud hosting platform uses the revolutionary ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for each and every file. All data that you upload will be saved in a RAID i.e. simultaneously on a large number of SSDs. A lot of file systems synchronize the files between the different drives using this type of a setup, but there's no real warranty that a file won't be corrupted. This could happen at the time of the writing process on any drive and afterwards a bad copy may be copied on all other drives. What is different on our platform is that ZFS compares the checksums of all files on all drives live and in case a corrupted file is located, it's swapped with a good copy with the correct checksum from some other drive. In this way, your info will remain undamaged no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

If you get one of our semi-dedicated hosting plans, you won't have to worry about silent file corruption since we use ZFS - an advanced file system that keeps track of all files in real time. Each time you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synced between multiple SSD drives for redundancy, so if one drive fails, the other ones will take control. 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 a different drive. This happens instantly, so there will be no danger for any part of your content at any time. In comparison, other file systems execute checks after a system malfunction, but since they don't use anything similar to the checksums which ZFS uses, they will not detect silently corrupted files, so a bad copy can be replicated on the other drives as well and you can lose crucial information. As this isn't the case with ZFS, we guarantee the integrity of each file you upload no matter what.
