Hi, > How can I refresh a backup of directory as Nero doing in windows ?
By xorriso: http://scdbackup.sourceforge.net/xorriso_eng.html http://scdbackup.sourceforge.net/README_xorriso http://scdbackup.sourceforge.net/xorriso-0.2.8.pl01.tar.gz > please specify the options as backup to a DVD Data directory . >From man xorriso Incremental backup of a few directory trees This does the following to directories /open_source_project and /personal_mail in the ISO image: create them if not existing yet, compare them with their disk counterparts, add disk file objects which are missing yet, overwrite those which are different on disk, and delete those which have vanished on disk. But do not add or overwrite files matching *.o, *.swp. $ xorriso -dev /dev/sr0 \ -volid PROJECTS_MAIL_"$(date '+%Y_%m_%d_%H%M%S')" \ -not_leaf '*.o' -not_leaf '*.swp' \ -update_r /home/thomas/open_source_projects /open_source_projects \ -update_r /home/thomas/personal_mail /personal_mail \ -commit -toc -eject all To be used several times on the same media, whenever an update of the two disk trees to the media is desired. Begin with blank media and start a new blank media when the run fails due to lack of remaining space on the old one. This makes sense if the full backup leaves substantial remaining capacity on media and if the expected changes are much smaller than the full backup. An update run will probably save no time but last longer than a full backup. With mount option -o "sbsector=" on Linux resp. -s on FreeBSD it is possible to access the session trees which represent the older backup versions. With CD media, Linux mount accepts session numbers directly by its option "session=". Multi-session media and most overwriteable media written by xorriso can tell the sbsectors of their sessions by xorriso option -toc. Sessions on multi-session media are separated by several MB of unused blocks. So with small sessions the payload capacity can become substantially lower than the overall media capacity. If the remaining space on media does not suffice for the next gap, the drive is supposed to close the media automatically. Better do not use your youngest backup for -update_r. Have at least two media which you use alternatingly. So only older backups get endangered by the new write operation, while the newest backup is stored safely on a different media. Always have a blank media ready to perform a full backup in case the update attempt fails due to insufficient remaining capacity. > What is the best GUI interface There is no GUI for xorriso yet. > used to manifest cdrecord options ? It is not about the burn program but about the ISO 9660 generator program. So your question is rather towards mkisofs. (I am curious what the answer will be.)
