No Data Corruption & Data Integrity
Find out what No Data Corruption & Data Integrity is and how it can be beneficial for the files in your website hosting account.
Data corruption is the damage of info because of various software or hardware failures. When a file is damaged, it will no longer function as it should, so an application will not start or will give errors, a text file can be partially or entirely unreadable, an archive file will be impossible to open and unpack, etc. Silent data corruption is the process of data getting damaged 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 in size hard disks where vast volumes of info are located. In case a drive is part of a RAID and the info on it is replicated on other drives for redundancy, it's very likely that the damaged file will be treated as an undamaged one and will be copied on all of the drives, making the harm permanent. Lots of the file systems which operate on web servers today often cannot identify corrupted files instantly or they need time-consuming system checks through which the server isn't functioning.
No Data Corruption & Data Integrity in Shared Hosting
We guarantee the integrity of the info uploaded in any shared hosting
account which is generated on our cloud platform since we employ the advanced ZFS file system. The latter is the only one which was designed to avert silent data corruption using a unique checksum for each file. We shall store your data on a number of SSD drives that work in a RAID, so the same files will be accessible on several places at the same time. ZFS checks the digital fingerprint of all the files on all drives in real time and if the checksum of any file is different from what it has to be, the file system swaps that file with an undamaged version from some other drive inside the RAID. There's no other file system which uses checksums, so it's easy for data to get silently corrupted and the bad file to be replicated on all drives over time, but since that can never happen on a server using ZFS, you will not have to worry about the integrity of your data.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
We've avoided any probability of files getting damaged silently as the servers where your semi-dedicated hosting
account will be created take advantage of a powerful file system called ZFS. Its basic advantage over other file systems is that it uses a unique checksum for every single file - a digital fingerprint that's checked in real time. Since we store all content on multiple SSD drives, ZFS checks if the fingerprint of a file on one drive matches the one on the rest of the drives and the one it has saved. In case there is a mismatch, the bad copy is replaced with a good one from one of the other drives and since it happens instantly, there is no chance that a damaged copy could remain on our website hosting servers or that it can be duplicated to the other hard drives in the RAID. None of the other file systems work with this type of checks and what is more, even during a file system check right after a sudden blackout, none of them can identify silently corrupted files. In comparison, ZFS doesn't crash after a power loss and the constant checksum monitoring makes a time-consuming file system check unnecessary.
