Data corruption is the accidental transformation of a file or the loss of information that often occurs during reading or writing. The reason may be hardware or software fail, and consequently, a file could become partially or entirely corrupted, so it will no longer function correctly because its bits will be scrambled or missing. An image file, for instance, will no longer present an actual image, but a random mix of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etcetera. In the event that such an issue appears and it's not recognized by the system or by an administrator, the data will be corrupted silently and if this happens on a drive that's a part of a RAID array where the information is synchronized between various drives, the corrupted file will be copied on all other drives and the harm will become permanent. A large number of popular file systems either do not offer real-time checks or don't have good ones which will detect a problem before the damage is done, so silent data corruption is a very common issue on internet hosting servers where large amounts of information are stored.
No Data Corruption & Data Integrity in Cloud Website Hosting
The integrity of the data which you upload to your new cloud website hosting
account shall be ensured by the ZFS file system that we take advantage of on our cloud platform. The vast majority of internet hosting suppliers, including our firm, use multiple hard disk drives to keep content and since the drives work in a RAID, the same data is synchronized between the drives all of the time. If a file on a drive gets corrupted for some reason, yet, it is very likely that it will be copied on the other drives as other file systems do not include special checks for this. In contrast to them, ZFS works with a digital fingerprint, or a checksum, for each file. In the event that a file gets damaged, its checksum will not match what ZFS has as a record for it, which means that the bad copy will be substituted with a good one from a different hard disk. As this happens in real time, there is no risk for any of your files to ever be corrupted.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
Your semi-dedicated hosting
account will be resistant to silent data corruption as all our storage servers employ the efficient ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, so as to verify the integrity of each file. When you upload content to your account, it'll be saved on a couple of redundant drives being employed in a RAID i.e. the files will be the same across all disks. All of the copies of a particular file will have the same checksum on all hard drives and ZFS will compare the checksums of the duplicates right away, so if it identifies a mismatch, which will indicate that one of the copies is corrupted, it'll substitute 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 won't be corrupted and there won't be any need for a time-consuming system check which other file systems perform following some failure, prolonging the time needed for the server to go back online. ZFS is the sole file system which can really protect your content from silent data corruption.
