Data corruption is the damage of info because of various software or hardware fails. After a file is damaged, it will no longer function as it should, so an app will not start or will give errors, a text file could be partially or entirely unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of information getting damaged without any acknowledgement by the system or an administrator, that makes it a serious problem for website hosting servers as fails are much more likely to occur on bigger hard disk drives where vast volumes of information are located. In case a drive is part of a RAID and the information on it is copied on other drives for redundancy, it's likely that the damaged file will be treated as a good one and it will be duplicated on all of the drives, making the harm permanent. A lot of the file systems which run on web servers these days often cannot locate corrupted files right away or they need time-consuming system checks through which the server is not working.

No Data Corruption & Data Integrity in Cloud Hosting

We've dealt with the problem of silent data corruption on all our cloud hosting servers by using the amazing Z file system, or ZFS. The latter is better than other file systems since it is the only one in existence that checks all of the files in real time by using a checksum - a digital identifier that is unique for each file. When you upload content to your account, it'll be stored on several SSD drives and regularly synced between them for redundancy. ZFS regularly compares the checksum of all files and when any file is detected as damaged, it's replaced immediately with a good copy from another disk. As this happens in real time, there's no risk that a damaged file may remain or may be duplicated on the rest of the SSDs. ZFS needs lots of physical memory to perform the real-time checks and the benefit of our cloud web hosting platform is that we work with multiple powerful servers working together. If you host your Internet sites with us, your information will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be shielded from silent data corruption because all our storage servers make use of the innovative ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, in order to ensure the integrity of every single file. When you upload content to your account, it will be saved on a couple of redundant drives operating in a RAID i.e. the files will be the same on all disk drives. All the copies of a given file will have the same checksum on all drives and ZFS will compare the checksums of the duplicates quickly, and if it identifies a mismatch, that will indicate that one of the copies is damaged, it will substitute that file with a healthy copy from one of the other disks. Even if there is a sudden blackout, the data on the servers will not get corrupted and there won't be any need for a time-consuming system check which other file systems perform after some failure, lengthening the time needed for the server to get back online. ZFS is the file system which can truly protect your content from silent data corruption.
