*nix Backup

Gnu Tar

GNU Tar supports everything needed to make a reliable backup (although I must say I don't know how well, if at all, it supports extended attributes). One major problem with tar is, that you have to pay close attention to the options you give (also at restore time), because the defaults are not suitable. Two major ones are –preserve-permissions and –numeric-owner. This could also include –same-owner, but a quick tests shows the –preserve-permissions option implies this. Should you have forgotten the –numeric-owner option for the backup command, this can also be given at restore time. Giving it at backup time, should negate the necessity of giving it at restore time.
