Operating Systems Linux How to Keep your core System and personal Data safe while updating to latest distro? Post 302657209 by methyl on Saturday 16th of June 2012 07:01:31 PM

Personally I reserve /home for system user home directories and use a totally different directory tree on its own mountpoint(s) for the user home directories.

Some Administrators use soft links from /home to user home directories on another filesystem. I don't, though it is a valid approach.


For the system data in say root, /usr, and /var, I would backup every significant configuration file and restore (or blend) those files as appropriate after an upgrade. Rehearse on an expendable test system until you get it right. It's not easy.

NAME
unburden-home-dir - unburdens home directories from caches and trashes SYNOPSIS
unburden-home-dir [ -n | -u | -f filter ] unburden-home-dir ( -h | --help | --version ) DESCRIPTION
unburden-home-dir unburdens the home directory from files and directory which cause high I/O or disk usage but are neither important if they are lost, e.g. caches or trash directory. When being run it moves the files and directories given in the configuration file to a location outside the home directory, e.g. /tmp or /scratch, and puts appropriate symbolic links in the home directory instead. OPTIONS
-f just unburden those directory matched by the given filter (a perl regular expression) -- matches the already unburdened directories if used together with -u. -F Do not check for files in use with lsof before (re)moving files. -n dry run (show what would be done) -u undo (reverse the functionality and put stuff back into the home directory) -h, --help show this help --version show the program's version EXAMPLES
Example configuration files can be found at /usr/share/doc/unburden-home-dir/examples on Debian-based systems and in the etc/ directory of the source tar ball. FILES
/etc/unburden-home-dir, /etc/unburden-home-dir.list, ~/.unburden-home-dir, ~/.unburden-home-dir.list, /etc/default/unburden-home-dir, /etc/X11/Xsession.d/95unburden-home-dir Read /usr/share/doc/unburden-home-dir/README on debianoid installations or README in the source tar ball for an explanation of these files.
