Several pointed out that I need not restore the files -- rather just
save the dump image. I wound up following the example of this snippet
from Rich Kulawiec's message:
=========================================
Alternatively, you could just skip the ufsrestore and do this:
ufsdump 5uf /ubk/var/level5.20040823.dump /var
which just scribbles the entire dump image in a file named for the
level and the date. This will run quite a bit faster (since ufsrestore
isn't even invoked) but it may not give you the confidence you're
looking for that the ufsdump worked. A workaround for *that* is:
ufsdump 5uf /ubk/var/level5.20040823.dump /var [same]
ufsrestore tvf /ubk/var/level5.20040823 > some.file.somewhere
which just catalogs the dump image afterwards.
=================================================
ORIGINAL MESSAGE:
All,
I've been able to ufsdump a file system to a large disk as a full backup,
but so far have been unsuccessful with incremental backups.
Is this possible with ufsdump?
The following command will work with a 0 level ufsdump but not for
a level 5 dump (the directory /ubk/var/5/20040823 already exists).
Result is:
----------------
DUMP: Date of this level 5 dump: Mon Aug 23 21:56:16 2004
DUMP: Date of last level 0 dump: Sun Aug 22 06:42:36 2004
DUMP: Dumping /dev/rdsk/c0t0d0s4 (mozart:/var) to standard output.
DUMP: Mapping (Pass I) [regular files]
DUMP: Mapping (Pass II) [directories]
DUMP: Mapping (Pass II) [directories]
DUMP: Mapping (Pass II) [directories]
DUMP: Writing 32 Kilobyte records
DUMP: Estimated 18254 blocks (8.91MB).
DUMP: Dumping (Pass III) [directories]
DUMP: Dumping (Pass IV) [regular files]
open: No such file or directory
cannot open symbol table file ./restoresymtable
DUMP: 18238 blocks (8.91MB) on 1 volume at 6157 KB/sec
DUMP: DUMP IS DONE

Thanks!
