Data corruption is the damage of data because of various hardware or software fails. After a file gets corrupted, it will no longer function correctly, so an application will not start or shall give errors, a text file could be partially or fully unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of data getting harmed without any identification by the system or an admin, that makes it a serious problem for website hosting servers as problems are very likely to occur on larger in size hard drives where substantial volumes of information are stored. When a drive is part of a RAID and the info on it is replicated on other drives for redundancy, it's likely that the bad file will be treated as a standard one and it will be copied on all of the drives, making the damage permanent. Lots of the file systems which run on web servers nowadays often are unable to detect corrupted files right away or they need time-consuming system checks through which the server is not operational.

No Data Corruption & Data Integrity in Cloud Hosting

The integrity of the data which you upload to your new cloud hosting account shall be guaranteed by the ZFS file system which we make use of on our cloud platform. The majority of internet hosting providers, like our company, use multiple hard disk drives to store content and because the drives work in a RAID, the same information is synchronized between the drives at all times. When a file on a drive becomes damaged for reasons unknown, yet, it is more than likely that it will be duplicated on the other drives since other file systems don't feature special checks for this. Unlike them, ZFS uses a digital fingerprint, or a checksum, for each and every file. If a file gets damaged, its checksum will not match what ZFS has as a record for it, therefore the bad copy shall be swapped with a good one from a different hard disk drive. Because 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

If you go for one of our semi-dedicated server packages, you will not have to be concerned about silent file corruption since we use ZFS - a high level file system that monitors all of the files in real time. Every time you upload a file to your website hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synchronized between several SSD drives for redundancy, so if a drive fails, the other ones will take control. ZFS compares the checksum of all the copies on the different drives and in case it detects a damaged copy, it replaces it with a healthy one from a different drive. This is done in real time, so there will be no risk for any part of your content at any moment. In comparison, all of the other file systems carry out checks only after a system breakdown, but since they do not use anything similar to the checksums which ZFS uses, they cannot detect silently corrupted files, so a bad copy may be replicated on the rest of the disks as well and you could lose precious data. Because this is not the case with ZFS, we are able to guarantee the integrity of each and every file you upload no matter what.
