Data corruption is the damage of data due to various software or hardware problems. Once a file gets damaged, it will no longer function accurately, so an app will not start or shall give errors, a text file could be partially or entirely unreadable, an archive file 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 more likely to happen on bigger hard disk drives where substantial volumes of information are kept. When a drive is a part of a RAID and the information on it is replicated on other drives for redundancy, it is likely that the damaged file will be treated as a standard one and it'll be copied on all of the drives, making the harm permanent. A lot of the file systems which run on web servers these days often are not able to recognize corrupted files right away or they need time-consuming system checks through which the server isn't working.

No Data Corruption & Data Integrity in Shared Website Hosting

The integrity of the data which you upload to your new shared website hosting account will be guaranteed by the ZFS file system that we take advantage of on our cloud platform. Most of the web hosting providers, like our company, use multiple HDDs to keep content and because the drives work in a RAID, identical data is synchronized between the drives all the time. If a file on a drive gets damaged for reasons unknown, however, it is more than likely that it will be copied on the other drives since alternative file systems do not have special checks for that. In contrast to them, ZFS works with a digital fingerprint, or a checksum, for each and every file. In case a file gets corrupted, its checksum won't match what ZFS has as a record for it, therefore the bad copy will be swapped with a good one from a different disk drive. Since this happens right away, there is no possibility for any of your files to ever get damaged.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be protected against silent data corruption as all our storage servers use the effective ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, in order to ensure the integrity of each file. When you upload content to your account, it will be stored on a couple of redundant drives employed in a RAID i.e. the files shall be the same on all disk drives. All of the copies of a particular file will feature the same checksum on all hard drives and ZFS will compare the checksums of the copies quickly, and if it finds a mismatch, which will indicate that one of the copies is damaged, it'll substitute that file with a good copy from one of the other disks. Even if there's an unexpected power loss, the data on the servers won't become corrupted and there will not be any need for a time-consuming system check that other file systems perform following some breakdown, lengthening the time needed for the server to go back online. ZFS is the only file system which can really protect your content from silent data corruption.
