[thebeatlesguru]

i wanna use command fbackup to backup something into one tape,but there is important files in that tape ,i wanna backup up new files after these files, can i use fbackup do that? if i can ,how can i do it?

fbackup is not supported to appending to tapes. Because 'fbackup writes a header onto the tape, you may not be able to get back to the first 'end of file marker', and when 'fbackup finishes writing to tape it rewinds.

If you wish to not take risks with overwriting important information on tapes, get another tape.

'tar' and 'cpio' are far better if you must follow this option. Another option is getting 'GNU tar' from here: http://hpux.connect.org.uk/hppd/hpux/Gnu/tar-1.13.25/

Hi,

fbckup doesn't have the option of appending, whereas you can do the same using tar with r option

GNU tar supports backing up files over 2Gb. See the link I provided in my previous posting.
