fbackup inconsistencies

[Robin King_1]

I'm trying to troubleshoot our backups at the moment, as I'm convinced our incremental backups are backing up data that hasn't changed.

I've been reading about ensuring that the same graph file is used for the full and incrementtal backups, as fbackup bases it's incremental on specific graph files. I've also ensured I have the -u switch, to update the DB.

I decided to run a littel test on my home directory.

I created the /tmp/graph graph file, and awked the contents of my directory, so it would backup every file.

fbackup -v -g /tmp/graph -u -0 -f /dev/rmt/0m

fbackup(1421): no history is available for graph file /tmp/graph (below level 0)
fbackup(1004): session begins on Tue Apr 6 15:02:59 2004
fbackup(3203): volume 1 has been used 0 time(s)
fbackup(3024): writing volume 1 to the output file /dev/rmt/0m

fbackup(1005): run time: 23 seconds

I then made changes to the test* files, and re-ran using level 1.

fbackup(1418): the last level 0 session for graph /tmp/graph was
started : Tue Apr 6 15:02:59 2004

16: test3
fbackup(1005): run time: 13 seconds

My question is, why have those other files been backed up when they haven't changed?

Hi

they are dirs

man page

Beginning at HP-UX Release 8.0, all directories lying on the path to a
file that qualifies for the incremental backup will also be on the
backup media, even if the directories do not qualify on their own
status.

I see your point, but there are no files in these direcories that qualify for backup.

Hi robin

Plz observe the output of Both backups.

The reason is u would have been loged into dt, and .dt files will be accessed, when ever u r in X11.

Try with an different directory where only flat files are there, certainly you will not find out extra files.

All the best.

I'm not logged into via an X session. I'm using straight telnet. But I'll try another directory.
