Mac übers Netzwerk/HDU sichern ( dump )

[Puste-Blume]

Kann man einen Mac / OSX 10.3 mit dump sichern ?
Jedes normale Unix kann das ( Linux,Solaris,usw ). Scheint bei OSX nicht zu klappen

-->
twiti:~ root# > /Volumes/TRANSFER/test.dmp
twiti:~ root# dump 0ucf /Volumes/TRANSFER/test.dmp /
DUMP: Date of this level 0 dump: Sat Dec 4 14:54:54 2004
DUMP: Date of last level 0 dump: the epoch
DUMP: Dumping / to /Volumes/TRANSFER/test.dmp
DUMP: bad sblock magic number
DUMP: The ENTIRE dump is aborted.


Gruss

Hallo Andrea,

da hätte Apple wohl diesen Umstand in seiner manpage zu dump erklären sollen:

The magic number is that for the Berkeley FFS file system, and is not
for the HFS+ system. Thus the "bad sblock magic number" error when when
tries to use dump on HFS+ files. But one might think that dump could be
used for OS X UFS files, given that the UFS file system was supposedly
derived from the FFS system. Well, apparently that depends on when you
formatted your UFS file system. If you formatted with Mac OS X Server
1.x or a "DP" version of OS X, dump will work. (These used a BSD-Unix
partition table.) Mac OS X PB, 10.x, and OS X Server 10.x use a
"Macintosh" partition table, so the magic number is not where the dump
code can find it.

Since "restore" isn't shipped with OS X 10.x (even though it is part of
Darwin), all of this info on dump may be of little consequence. However,
IMHO this does point up some serious issues with Mac OS X:
1. Even though dump/restore may be a bit archaic, many Unix users
(myself included) would use dump/restore unless there is something
better in the offing.
2. Apple should not have allow a broken dump to appear in /sbin/dump, or
at least should have put a bug note on the man page.
3. While dump is certainly not restricted to FFS file systems (there is
Linux dump), I don't know what the implications of the retention of the
resource fork in HFS+ mean with respect to a dump for HFS+. BUT, if
Apple wants to see rapid adoption of OS X, they should have made sure
some sort of backup utility was shipped.
4. The fact that there are now two UFS systems is terrible. It opens the
whole question of just what Apple means when they say Darwin is the
underpinning of OS X. We need a consistent Unix base for OS X, and if
that is different from Darwin, Apple should say so.

Ich gehe recht in der Annahme, dass du dein System HFS+ formatiert hast?

jup, mit hfs+

wäre ja auch zu schön gewesen. Ich hab am Server ein Tape, und könnte dann den Mac durch einen Dump mitsichern lassen. Aber naja......
