I been looking for a way to backup source for sometime. Like a dvd iso disc. I started to look for away to do this after seeing 2012. It got me thinking of how to rebuild a compete archlinux system. This would also help us with are world domination plans. Joking aside, here is the script below: http://arch-live.isawsome.net/devel/backup-src.sh My script uncompresses the source code archives and re-compress them has $pkgname-$pkgver-$pkgrel.src.tar.lzma. I put the newer files in $SRCDEST/$repo folder. This makes it easier to find. It example below backups up all sources of extra repo in /var/abs/extra folder. ./backup-src.sh extra example below backups just abs source folder in /var/abs/extra. Including the abs archive uncompressed in abs/src folder. ./backup-src.sh extra abs I have seen some good compressing improvement when everything is re-compressed as .tar.lzma. For example chromium: chromium original archive is 130mb chromium re-compressed with .tar.lzma is 101.1mb You can extra the newer archives and build with 'makepkg -e'. I hope this helps.
