I have an old Solaris 2.5.1 system that cannot be updated. I need some code or a tool to do full and differential backups of a specific directory. Solaris 2.5.1 ufsdump will not successfully do a differential dump of a specific directory as /etc/dumpdates is not updated. It appears the N flag would take care of this problem but is not available for ufsdump in 2.5.1
All files will be FTP'd weekly. Basic requirement is to ftp only files that have changed since the last full FTP. Files may be compressed, dumped, or zipped into a single file before the FTP. Does anybody have a suggestion on how else I can complete this task.
