Explanation
Deduplication is a technique that reduces the amount of storage space required by eliminating duplicate or redundant data blocks. Deduplication can be performed at the file level, where entire files are compared and removed if they are identical, or at the block level, where chunks of data within a file are compared and removed if they are identical. Deduplication can be especially effective for VDI (Virtual Desktop Infrastructure) environments, where multiple virtual desktops share the same base image and have a high degree of similarity. By deduplicating the data blocks across the virtual desktops, the storage space required for the VDI volume can be significantly reduced, which can mitigate the situation of the storage being 80% full.
