Hopefully there are some other people on the list with AIX 5 experience,
mine stops at AIX 4.
Yes, backup is the AIX name for dump, it is a block level backup
utility rather than file level. One of its features is the
ability to backup by file name or by i-node, but most other versions
of dump can do the same.
No, it is not compatible with other versions of dump (dump usually is OS
specific, though I think Linux and Solaris dump formats can sometimes
work with each other). You will need to use the restore program on
AIX to read the archive. I can send you the backup/restore
AIX man pages via e-mail, no point in cluttering the list with
them.
