No Data Corruption & Data Integrity
Find out what No Data Corruption & Data Integrity is and how it could be beneficial for the files inside your web hosting account.
Data corruption is the damage of information because of various software or hardware problems. The moment a file gets damaged, it will no longer work as it should, so an app will not start or will give errors, a text file will be partially or completely 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 administrator, that makes it a significant problem for website hosting servers as fails are very likely to occur on larger hard disks where significant volumes of info are placed. In case a drive is part of a RAID and the info on it is duplicated on other drives for redundancy, it is likely that the damaged file will be treated as a healthy one and will be duplicated on all of the drives, making the damage permanent. A lot of the file systems which run on web servers nowadays often cannot find corrupted files right away or they need time-consuming system checks through which the server is not operational.
No Data Corruption & Data Integrity in Shared Web Hosting
The integrity of the data which you upload to your new shared web hosting
account will be guaranteed by the ZFS file system that we take advantage of on our cloud platform. Most of the web hosting service providers, like our firm, use multiple HDDs to keep content and considering that 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 whatever reason, however, it is very likely that it will be copied on the other drives because other file systems don't feature special checks for this. In contrast to them, ZFS employs a digital fingerprint, or a checksum, for each file. If a file gets corrupted, its checksum will not match what ZFS has as a record for it, which means that the bad copy shall 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 Hosting
Your semi-dedicated hosting
account will be resistant to silent data corruption because all of our storage servers employ the effective ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, in order to ensure the integrity of each file. When you upload content to your account, it will be saved on a couple of redundant drives employed in a RAID i.e. the files shall be the same across all drives. All copies of a given file will have the same checksum on all hard drives and ZFS will compare the checksums of the duplicates in real time, and if it discovers a mismatch, that would indicate that one of the copies is damaged, it'll swap that file with a healthy copy from one of the other drives. Even if there is an unforeseen power loss, the data on the servers will not be corrupted and there won't be any need for a time-consuming system check which other file systems perform after some breakdown, prolonging the time needed for the server to return online. ZFS is the only file system that can truly protect your content from silent data corruption.
