Linux backup scripts, ασφάλεια με copy paste

Δεν χρειάζεται να κάτσεις να σκεφτείς τρόπους και να χάνεσαι στα documentation και στις man pages. Έκανα εγώ την βρώμικη δουλειά για ‘σένα. Δεν έχεις να κάνεις τίποτα άλλο παρά να αντιγράψεις τα παρακάτω script ή μέρη αυτών, να τα πειράξεις κατάλληλα και να απολαύσεις τα backup. Έχω σχολιάσει αρκετά τον κώδικα οπότε δε νομίζω να χρειάζεται παραπάνω εξήγηση. Δεν ξέρω αν υπάρχει άλλος, καλύτερος τρόπος ή αν έκανα κάποιο λάθος στις εντολές. Δουλεύει μια χαρά και δεν υπάρχει λόγος να το πειράξω 🙂
