FSlint has both a GUI as well as a command line interface. Aside from finding duplicate files, FsLint is also capable of searching for problematic filenames, temporary files, bad symlinks, empty directories and non-stripped binaries. So let me show you how to install and use FsLint.
BackupPC is a Disk-to-disk backup software suite that is considered as one of the most popular free and open-source backup software. It has a web-based frontend with no need for client as the server is itself a client for several protocols, which are handled by other services native to the client OS. BackupPC is using a combination of hard links to reduce the total disk space utilized for files. During the first full backup, each and every file is transferred to the backend, optionally compressed, and then compared. All similar files are hard linked and use only one additional directory entry.
vm.swappiness is a tunable kernel parameter that controls how much the kernel favors swap over RAM. At the source code level, it’s also defined as the tendency to steal mapped memory. A high swappiness value means that the kernel will be more apt to unmap mapped pages. A low swappiness value means the opposite, the kernel will be less apt to unmap mapped pages. In other words, the higher the vm.swappiness value, the more the system will swap.

hdparm provides a command line interface to various kernel interfaces supported by the Linux SATA/PATA/SAS “libata” subsystem and the older IDE driver subsystem. Many newer (2008 and later) USB drive enclosures now also support “SAT” (SCSI-ATA Command Translation) and therefore may also work with hdparm.
