Data corruption is the damage of information because of various hardware or software fails. Once a file is damaged, it will no longer function accurately, so an application will not start or shall give errors, a text file will be partially or completely unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of data getting damaged without any acknowledgement by the system or an admin, that makes it a significant problem for website hosting servers as fails are very likely to occur on larger in size hard disks where large volumes of information are placed. In case a drive is part of a RAID and the information on it is copied on other drives for redundancy, it is more than likely that the bad file will be treated as a regular one and it will be copied on all drives, making the harm permanent. A lot of the file systems that operate on web servers nowadays often are not able to recognize corrupted files immediately or they need time-consuming system checks through which the server isn't functioning.

No Data Corruption & Data Integrity in Cloud Hosting

If you host your sites in a cloud hosting account from our firm, you don't have to worry about any of your data ever getting damaged. We can guarantee that since our cloud hosting platform works with the advanced ZFS file system. The aforementioned is the only file system that uses checksums, or unique digital fingerprints, for every single file. All the info that you upload will be saved in a RAID i.e. simultaneously on numerous SSD drives. All the file systems synchronize the files between the different drives using this type of a setup, but there is no real guarantee that a file won't get corrupted. This may occur during the writing process on each drive and then a damaged copy can be copied on the rest of the drives. What is different on our platform is that ZFS compares the checksums of all files on all the drives immediately and if a corrupted file is found, it's replaced with a good copy with the correct checksum from some other drive. That way, your info will remain unharmed no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You will not have to deal with any silent data corruption issues whatsoever should you purchase one of our semi-dedicated server packages because the ZFS file system that we work with on our cloud hosting platform uses checksums to guarantee that all of the files are intact all of the time. A checksum is a unique digital fingerprint which is given to each and every file stored on a server. Because we store all content on a number of drives at the same time, the same file has the same checksum on all 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 rest of the hard disks. ZFS is the only file system on the market that uses checksums, which makes it much more reliable than other file systems which cannot detect silent data corruption and duplicate bad files across hard drives.
