- What I've always done is the following:
-
- (a) take a full backup once a week - in this case, a 'mksysb' flavor.
- (b) The backup script touches /fulldump
- (c) The incremental does a 'find / -newer /fulldump -print | backup -i'
-
- In case of failure, you just spin the mksysb - this gets you something
- back that will at least *BOOT*. Then you just /etc/restore the incremental
- over the now-semi-functional system.
-
- I don't see that backup-by-inode is a big issue - the functionality
- is there via other means.
