dumping non-continuous ranges using svnadmin dump

I have a repository called "sandbox" whose HEAD is at revision 20. I would
like to dump revisions 1 to15 and then from 18 to19. Basically I want to
skip revision 16,17 and 20.
The command:

# svnadmin dump -r 1:15 -r 18:19 sandbox > sanbox-dumpfile

gives error message:
svnadmin: Multiple revision arguments encountered; try '-r N:M' instead of
'-r N -r M'
and the command:
#svnadmin dump -r 1:15,18:19 sandbox > sanbox-dumpfile

gives error message:
svnadmin: Syntax error in revision argument '1:15,18:19'
How can I do this?

Thanks.

Investigate svnadmin dump's --incremental and/or --deltas flags.

Tried but does not work...

# svnadmin load sandbox-restore < sandbox-dumpfile
The above command restored it up to 15 revision as expected:
<snip>
<<< Started new transaction, based on original revision 15
     * editing path : PartA/trunk/source/README.txt ... done.

------- Committed revision 15 >>>
</snip>

and then the following command:
# svnadmin load sandbox-restore < sandbox-dump2

gave the error message:

<snip>
<<< Started new transaction, based on original revision 18
svnadmin: File already exists: filesystem 'sandbox-restore/db', transaction
'18-a', path 'PartA'
     * adding path : PartA ...
</snip>

The first method also ended up with the same error message.

Any more ideas?

Thanks.

Yeah, I don't think you can specify multiple revision ranges like that. How about:

svnadmin dump -r 1:15 sandbox > sandbox-dumpfile
svnadmin dump -r 18:19 sandbox >> sandbox-dumpfile

I'm not sure if that yields a legal dumpfile. If not, try:

svnadmin dump -r 1:15 sandbox > sandbox-dumpfile
svnadmin dump -r 18:19 sandbox > sandbox-dumpfile2

Then when it comes time to load, load the first file, then the second.
