1: Any recommendations for the best tool to create a full backup of the system? At the moment the likely target for backups will be the existing network storage unit (which was about half full until I reorganized my iTunes directory and caused my nightly incremental on the Linux box to grow, but should be around there once the new full backup is done replacing a month's worth of incremental backups). But I shortly may move to a directly connected external that I'd like to set up as a potential emergency boot disk as well.
2: Any recommendations for a good reference book on Mac and OS X for someone whose used *nix for 26 years.
Thank you in advance.
