You may also save less disk space in the backup than with gzip, but (I think) gain in speed by doing a sparse file (again with a recent dd): dd bs=4096 if=/dev/sdx of=DeadStick.[date] conv=sparse status=progress -- francis.montagnac@xxxxxxxx, SIC-SAM, Tel: (33) 04 92 38 79 11, Bur: C111 INRIA Sophia, 2004, route des Lucioles - BP 93 06902 Sophia Antipolis Cedex _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
