Yes, there are solutions available for file compression at the filesystem level in Linux. One such solution is transparent compression using the LZO or ZFS file systems.LZO File System: The LZO file system is a lightweight, read-only compressed file system. It allows you to create a compressed file system that can be mounted and accessed like any other file system. The compression is transparent, meaning the files are automatically compressed and decompressed on the fly as they are read or written.
