Hello again, Here a session of a backup archive is written to a DVD.
xorriso -for_backup -dev /dev/sr0 \ -update_r . / \ -commit \ -toc -check_md5 failure -- \ -eject all This command gives the contents of a DVD. xorriso -dev /dev/sr0 -toc TOC layout : Idx , sbsector , Size , Volume Id ISO session : 1 , 0 , 678303s , ISOIMAGE ISO session : 2 , 716368 , 13376s , ISOIMAGE ISO session : 3 , 737600 , 816699s , ISOIMAGE ... Session time stamps would help when recovering from a storage failure. Eg. Date TOC layout : Idx , sbsector , Size , Volume Id 2023-07-23 ISO session : 1 , 0 , 678303s , ISOIMAGE 2023-07-29 ISO session : 2 , 716368 , 13376s , ISOIMAGE 2023-08-06 ISO session : 3 , 737600 , 816699s , ISOIMAGE Can the current xorriso include session timestamps? In the manual I see file timestamps mentioned. Not session timestamps. Thx, ... P. - mobile: +1 778 951 5147 VoIP: +1 604 670 0140
