Data corruption is the damage of data because of various software or hardware failures. After a file is damaged, it will no longer work as it should, so an application will not start or will give errors, a text file shall be partially or entirely unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of info getting damaged without any identification by the system or an admin, which makes it a serious problem for website hosting servers as fails are very likely to happen on bigger hard disk drives where substantial volumes of information are kept. In case a drive is part of a RAID and the data on it is copied on other drives for redundancy, it is very likely that the bad file will be treated as a good one and will be duplicated on all of the drives, making the harm permanent. Lots of the file systems that operate on web servers nowadays often are not able to find corrupted files instantly or they need time-consuming system checks through which the server is not working.

No Data Corruption & Data Integrity in Shared Hosting

The integrity of the data that you upload to your new shared hosting account shall be guaranteed by the ZFS file system that we take advantage of on our cloud platform. Most internet hosting service providers, like our company, use multiple HDDs to store content and considering that the drives work in a RAID, the same information is synchronized between the drives all of the time. If a file on a drive gets damaged for whatever reason, yet, it's very likely that it will be duplicated on the other drives as other file systems don't feature special checks for that. Unlike them, ZFS applies a digital fingerprint, or a checksum, for every single file. If a file gets corrupted, its checksum will not match what ZFS has as a record for it, and the damaged copy will be substituted with a good one from another hard drive. Since this happens immediately, there is no possibility for any of your files to ever get corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be shielded from silent data corruption as all of our storage servers employ the effective ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, so as to guarantee the integrity of each file. When you upload content to your account, it will be placed on several redundant drives in a RAID i.e. the files will be the same across all disk drives. All the copies of a specific file will feature the same checksum on all drives and ZFS will compare the checksums of the copies quickly, and 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 drives. Even if there is 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 which other file systems perform after some breakdown, extending the time needed for the server to get back online. ZFS is the file system which can really protect your content from silent data corruption.
