One of the brand new mint tools scheduled to be included in Linux Mint 5 is mintBackup, a backup tool which lets you save the content of your home directory into a single file, which you can then easily restore on another partition/computer or wherever you want really.
The tool works fine and is fully stable. It will be packaged in the days to come and announcements will be made for the community to test and translate it.
As the preferred way of upgrading to a newer release is to perform a fresh installation from the CD, this tool will ease the process of migrating data and hidden configuration files.
