Data corruption is the damage of data because of various hardware or software failures. The moment a file gets damaged, it will no longer work properly, so an app will not start or shall give errors, a text file could be partially or entirely unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of info getting harmed without any identification by the system or an administrator, that makes it a significant problem for web hosting servers as fails are very likely to happen on bigger hard disks where vast volumes of info are stored. In case a drive is part of a RAID and the information on it is duplicated on other drives for redundancy, it's more than likely that the damaged file will be treated as a standard one and it'll 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 discover corrupted files instantly or they need time-consuming system checks through which the server is not operational.

No Data Corruption & Data Integrity in Website Hosting

If you host your Internet sites in a website hosting account with our firm, you don't have to worry about your data ever getting corrupted. We can ensure that due to the fact that our cloud hosting platform employs the state-of-the-art ZFS file system. The latter is the only file system that works with checksums, or unique digital fingerprints, for each file. All of the info that you upload will be stored in a RAID i.e. simultaneously on many different SSDs. Many file systems synchronize the files between the different drives with such a setup, but there is no real guarantee that a file won't be corrupted. This may happen at the time of the writing process on any drive and afterwards a damaged copy can be copied on the other drives. What is different on our platform is that ZFS analyzes the checksums of all files on all drives in real time and in case a corrupted file is identified, it is swapped with a good copy with the correct checksum from some other drive. That way, your data will continue to be intact no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You won't have to deal with any kind of silent data corruption issues if you buy one of our semi-dedicated server plans since the ZFS file system that we take advantage of on our cloud hosting platform uses checksums to guarantee that all of the files are intact all the time. A checksum is a unique digital fingerprint that is allotted to each and every file stored on a server. Because we store all content on a number of drives simultaneously, the same file has the same checksum on all the drives and what ZFS does is that it compares the checksums between the different drives in real time. In the event that it detects that a file is corrupted and its checksum is different from what it should be, it replaces that file with a healthy copy right away, avoiding any possibility of the damaged copy to be synchronized on the remaining drives. ZFS is the only file system available on the market which uses checksums, which makes it far superior to other file systems that are not able to identify silent data corruption and copy bad files across drives.
