Data corruption is the damage of data caused by various software or hardware problems. When a file gets corrupted, it will no longer function accurately, so an app will not start or shall give errors, a text file can be partially or completely unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of information getting harmed without any acknowledgement by the system or an admin, which makes it a significant problem for website hosting servers as fails are much more likely to occur on larger hard disks where considerable volumes of information are stored. If a drive is part of a RAID and the info on it is replicated on other drives for redundancy, it is very likely that the damaged file will be treated as an undamaged one and will be duplicated on all of the drives, making the damage permanent. A huge number of the file systems which operate on web servers these days often cannot recognize corrupted files instantly or they need time-consuming system checks during which the server is not functioning.
No Data Corruption & Data Integrity in Website Hosting
The integrity of the data that you upload to your new website hosting
account shall be guaranteed by the ZFS file system which we work with on our cloud platform. The vast majority of hosting suppliers, like our firm, use multiple hard disk drives to store content and because the drives work in a RAID, identical info is synchronized between the drives at all times. When a file on a drive becomes corrupted for some reason, yet, it is likely that it will be reproduced on the other drives as alternative file systems don't offer special checks for this. In contrast to them, ZFS uses a digital fingerprint, or a checksum, for every file. In case a file gets damaged, its checksum will not match what ZFS has as a record for it, and the damaged copy shall be swapped with a good one from a different drive. Since this happens right away, there is no possibility for any of your files to ever get corrupted.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
Your semi-dedicated hosting
account will be resistant to silent data corruption because all of our storage servers make use of the efficient ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, in order to guarantee the integrity of every single file. When you upload content to your account, it will be saved on several redundant drives being employed in a RAID i.e. the files shall be the same across all disks. All of the copies of a specific file will feature the same checksum on all hard drives and ZFS will compare the checksums of the copies quickly, and if it identifies a mismatch, that would indicate that one of the copies is damaged, it'll swap that file with a good copy from one of the other drives. Even if there's a sudden power failure, the data on the servers will not be corrupted and there won't be any need for a time-consuming system check that other file systems perform following some malfunction, lengthening the time needed for the server to get back online. ZFS is the sole file system which can really protect your content from silent data corruption.
