Data corruption is the damage of information caused by various hardware or software problems. The moment a file is corrupted, it will no longer work as it should, so an app will not start or shall give errors, a text file can be partially or fully unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of info getting harmed without any acknowledgement by the system or an administrator, that makes it a significant problem for web hosting servers as failures are more likely to occur on bigger hard drives where large volumes of information are stored. When a drive is a part of a RAID and the information on it is duplicated on other drives for redundancy, it's likely that the damaged file will be treated as a standard one and it will be duplicated on all of the drives, making the harm permanent. A lot of the file systems that run on web servers nowadays often are unable to discover corrupted files immediately or they need time-consuming system checks during which the server isn't functioning.

No Data Corruption & Data Integrity in Shared Hosting

If you host your Internet sites in a shared hosting account from our firm, you will not need to worry about your data ever getting damaged. We can ensure that because our cloud hosting platform uses the outstanding ZFS file system. The aforementioned is the only file system that uses checksums, or unique digital fingerprints, for every single file. Any kind of data that you upload will be kept in a RAID i.e. simultaneously on many different SSDs. A lot of file systems synchronize the files between the different drives using such a setup, but there's no real guarantee that a file won't be corrupted. This could happen during the writing process on each drive and after that a bad copy can be copied on the other drives. What is different on our platform is the fact that ZFS examines the checksums of all files on all the drives right away and if a corrupted file is found, it is replaced with a good copy with the correct checksum from some other drive. This way, your info will remain intact no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You won't experience any kind of silent data corruption issues whatsoever in case you purchase one of our semi-dedicated server solutions because the ZFS file system that we work with on our cloud hosting platform uses checksums in order to guarantee that all of the files are intact at all times. A checksum is a unique digital fingerprint which is assigned to each and every file saved on a server. As we store all content on a number of drives simultaneously, the same file has the same checksum on all drives and what ZFS does is that it compares the checksums between the different drives right away. If 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 without delay, avoiding any probability of the damaged copy to be synchronized on the rest of the drives. ZFS is the only file system available on the market which uses checksums, which makes it far superior to other file systems which are not able to identify silent data corruption and copy bad files across drives.
