Data corruption is the accidental change of a file or the losing of information which often occurs during reading or writing. The reason may be hardware or software malfunction, and for that reason, a file can become partially or entirely corrupted, so it'll no longer function properly since its bits will be scrambled or lacking. An image file, for instance, will no longer display an accurate image, but a random combination of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etcetera. If this kind of a problem appears and it isn't found by the system or by an admin, the data will become corrupted silently and when this happens on a drive which is a part of a RAID array where the data is synced between different drives, the corrupted file shall be duplicated on all other drives and the harm will be long term. Many frequently used file systems either don't have real-time checks or do not have high quality ones that will detect a problem before the damage is done, so silent data corruption is a common matter on web hosting servers where substantial volumes of information are stored.
No Data Corruption & Data Integrity in Shared Hosting
The integrity of the data that you upload to your new shared hosting
account will be ensured by the ZFS file system which we make use of on our cloud platform. Most hosting suppliers, like our company, use multiple hard disks to store content and since the drives work in a RAID, identical info is synchronized between the drives all the time. In case a file on a drive gets damaged for reasons unknown, yet, it's very likely that it will be reproduced on the other drives since alternative file systems do not offer special checks for this. In contrast to them, ZFS employs a digital fingerprint, or a checksum, for every single file. In case a file gets corrupted, its checksum will not match what ZFS has as a record for it, so the bad copy shall be substituted with a good one from a different hard disk drive. As this happens in real time, there is no possibility for any of your files to ever be damaged.
No Data Corruption & Data Integrity in Semi-dedicated Servers
Your semi-dedicated server
account will be resistant to silent data corruption since all our storage servers work with the advanced ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, so as to ensure 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 shall be the same across all disks. All of the copies of a particular file will have the same checksum on all hard disks and ZFS will compare the checksums of the duplicates right away, so if it registers a mismatch, which 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 an unforeseen power loss, the data on the servers won't become corrupted and there won't be any need for a time-consuming system check that other file systems perform following some failure, lengthening the time needed for the server to get back online. ZFS is the sole file system that can really protect your content from silent data corruption.
