Data corruption is the accidental change of a file or the loss of info that usually occurs during reading or writing. The reason can be hardware or software failure, and for that reason, a file could become partially or fully corrupted, so it will no longer function properly as its bits shall be scrambled or lacking. An image file, for instance, will no longer display an authentic image, but a random combination of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etcetera. In case such an issue occurs and it isn't identified by the system or by an administrator, the data will be corrupted silently and if this happens on a disk drive that is a part of a RAID array where the information is synchronized between various drives, the corrupted file shall be replicated on all other drives and the damage will be long term. Many popular file systems either do not feature real-time checks or don't have good ones that can detect a problem before the damage is done, so silent data corruption is a very common problem on internet hosting servers where large volumes of data are stored.
No Data Corruption & Data Integrity in Hosting
The integrity of the data which you upload to your new hosting
account will be guaranteed by the ZFS file system that we take advantage of on our cloud platform. Most of the internet hosting providers, including our company, use multiple HDDs to keep content and since the drives work in a RAID, the exact same info is synchronized between the drives at all times. When a file on a drive gets corrupted for some reason, however, it's likely that it will be copied on the other drives since other file systems do not have 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, therefore the bad copy will be replaced with a good one from a different hard disk. Since this happens right away, there's no risk 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 resistant to silent data corruption as all our storage servers employ the innovative ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, in order to ensure the integrity of each and every file. When you upload content to your account, it'll be saved on several redundant drives employed 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 duplicates in real time, so if it identifies a mismatch, that would 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 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 which other file systems perform after some malfunction, lengthening the time needed for the server to go back online. ZFS is the sole file system that can really protect your content from silent data corruption.
