Data corruption is the damage of data because of various software or hardware fails. The moment a file is corrupted, it will no longer work accurately, so an application will not start or will give errors, a text file could be partially or fully unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of data getting damaged without any acknowledgement by the system or an administrator, which makes it a significant problem for website hosting servers as fails are much more likely to happen on bigger hard disks where substantial volumes of information are kept. When a drive is part of a RAID and the information on it is duplicated on other drives for redundancy, it is more than likely that the bad file will be treated as a good one and it'll be copied on all of the drives, making the harm permanent. A lot of the file systems which operate on web servers nowadays often cannot detect corrupted files instantly or they need time-consuming system checks through which the server is not functioning.
No Data Corruption & Data Integrity in Website Hosting
In case you host your Internet sites in a website hosting account from our company, you do not have to worry about your data ever getting corrupted. We can ensure that because 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 every single file. All data that you upload will be kept in a RAID i.e. simultaneously on multiple NVMe drives. All the file systems synchronize the files between the different drives using this type of a setup, but there's no real guarantee that a file won't get corrupted. This may happen at the time of the writing process on each drive and afterwards a damaged copy may be copied on the rest of the drives. What is different on our platform is the fact that ZFS compares the checksums of all files on all the drives right away and when a corrupted file is identified, it's replaced with a good copy with the correct checksum from some other drive. In this way, your information will stay unharmed no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
Your semi-dedicated hosting account will be protected against silent data corruption since all of our storage servers use the efficient ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, so as to guarantee the integrity of every single file. When you upload content to your account, it will be kept on a couple of redundant drives being employed in a RAID i.e. the files will be the same across all disk drives. All copies of a specific file will have the same checksum on all drives and ZFS will compare the checksums of the copies quickly, so if it finds a mismatch, that would indicate that one of the copies is corrupted, it'll substitute that file with a healthy copy from one of the other disks. Even if there's an unforeseen power failure, the data on the servers will not get corrupted and there will not be any need for a time-consuming system check which other file systems perform following some failure, extending the time needed for the server to get back online. ZFS is the sole file system that can truly protect your content from silent data corruption.
