Data corruption is the unintended modification of a file or the losing of information which usually occurs during reading or writing. The reason can be hardware or software malfunction, and due to this fact, a file can become partially or fully corrupted, so it will no longer function properly as its bits shall be scrambled or lacking. An image file, for example, will no longer show a real image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, and so on. When such a problem appears and it isn't found by the system or by an administrator, the data will become corrupted silently and if this happens on a drive that is a part of a RAID array where the information is synced between various drives, the corrupted file shall be duplicated on all of the other drives and the damage will become long term. Numerous popular file systems either don't have real-time checks or do not have high quality ones that can detect an issue before the damage is done, so silent data corruption is a rather common issue on hosting servers where large volumes of info are kept.
No Data Corruption & Data Integrity in Shared Hosting
The integrity of the data which you upload to your new shared hosting
account shall be guaranteed by the ZFS file system which we employ on our cloud platform. The vast majority of web hosting service providers, like our firm, use multiple HDDs to store content and considering that the drives work in a RAID, exactly the same data is synchronized between the drives all the time. When a file on a drive gets corrupted for whatever reason, however, it's likely that it will be duplicated on the other drives since alternative file systems don't feature special checks for this. Unlike them, ZFS employs a digital fingerprint, or a checksum, for each file. If a file gets damaged, its checksum won't match what ZFS has as a record for it, and the damaged copy will be replaced with a good one from another drive. Due to the fact that this happens right away, there's no risk 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 of our storage servers work with the state-of-the-art 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 stored on several redundant drives being employed in a RAID i.e. the files shall be the same on all disk drives. All 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 identifies a mismatch, that would indicate that one of the copies is corrupted, it will swap that file with a good copy from one of the other disks. Even if there is an unexpected power failure, the data on the servers won't get corrupted and there won't be any need for a time-consuming system check which 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 truly protect your content from silent data corruption.
