Install squashfs-tools and use mksquashfs to make compressed filesystems (similar to tar archives but mountable). The standard gentoo-sources are already patched with squashfs so you only have to enable it in the kernel config. To do online backups of my desktop system I have a script that backs up my whole root filesystem with the exception of some files (especially some sensitive ones in /etc). I do separate backups of /etc. Occasionally I use my squashfs backups to create livedvds. I use a genkernel initrd that is patched to use unionfs for copy on write functionality.
