- I'd like to set up a system using cpio to make full backups followed
- by daily GNUtar incrementals. (This is for SysV where dump isn't
- an option). I'll probably base the incrementals on the full backup time
- rather than each other so a complete restore only takes two tapes.
- Problems: Using the -N date option, all the directories on the filesystem
- are archived even if they are older than the specified date. Also, the
- +listed-incremental option seems to be the best way to handle incremental
- backups, but it expects to be given a filename containing a list of
- directories seen by the previous run. Otherwise it considers all the
- directories to be new and archives all their contents. If I use cpio for
- the full backup, I don't such a list for the incremental. Is there an
- easier way to create one than doing a dummy tar to /dev/null? Maybe a
- perl script that would generate the file with device and inode numbers
- and directory names? Or a hack to gnutar to create the file and quit?
