yes, as root can backup to /restorebu
root@bootp ~]# cd /home/byers
[root@bootp byers]# cd drhmail08
[root@bootp drhmail08]# ls *dec*
rhdec08  rhdec08~  rhdec08old
[root@bootp drhmail08]# bu -d /restorebu rhdec08

Incremental:      on
Backup directory: /restorebu

/home/byers/drhmail08/rhdec08 -> /restorebu/home/byers/drhmail08/rhdec08

[root@bootp drhmail08]#
do another file:
root@bootp byers]# bu -d /restorebu drhmail09

Incremental:      on
Backup directory: /restorebu

/home/byers/drhmail09 -> /restorebu/home/byers/drhmail09
/home/byers/drhmail09/rhjan09 -> /restorebu/home/byers/drhmail09/rhjan09

[root@bootp byers]#


then tried  to bu from /restorebu  to a new dir /restorebu2
and it also worked.  So i dont get the previos problem!?
[root@bootp drhmail09]# mkdir /restorebu2
[root@bootp drhmail09]# bu -d /restorebu2 /restorebu

Incremental:      on
Backup directory: /restorebu2

/restorebu -> /restorebu2/restorebu
/restorebu/.autofsck -> /restorebu2/restorebu/.autofsck
/restorebu/.autorelabel -> /restorebu2/restorebu/.autorelabel
/restorebu/home -> /restorebu2/restorebu/home
/restorebu/home/byers -> /restorebu2/restorebu/home/byers
/restorebu/home/byers/drhmail08 ->
/restorebu2/restorebu/home/byers/drhmail08
/restorebu/home/byers/drhmail08/rhdec08 ->
/restorebu2/restorebu/home/byers/drhmail08/rhdec08
/restorebu/home/byers/drhmail09 ->
/restorebu2/restorebu/home/byers/drhmail09
/restorebu/home/byers/drhmail09/rhjan09 ->
/restorebu2/restorebu/home/byers/drhmail09/rhjan09

[root@bootp drhmail09]#


so, I now  cant duplicate the problem!

just to confirm, i also then rm'd the files just bu'd to /restorebu
[root@bootp restorebu]# pwd
/restorebu
[root@bootp restorebu]# ls
home
[root@bootp restorebu]# rm -rf home
[root@bootp restorebu]#

and then redid the orginal (if not verbatim)
[root@bootp byers]# bu -d /restorebu drhmail09

Incremental:      on
Backup directory: /restorebu

/home/byers/drhmail09 -> /restorebu/home/byers/drhmail09
/home/byers/drhmail09/.#rhjan09 -> /restorebu/home/byers/drhmail09/.#rhjan09
/home/byers/drhmail09/#rhjan09# -> /restorebu/home/byers/drhmail09/#rhjan09#
/home/byers/drhmail09/rhjan09 -> /restorebu/home/byers/drhmail09/rhjan09

[root@bootp byers]#

so now it is working as it should, no explanation as to
original failure.
I dont know why that
/home/byers/drhmail09/.#rhjan09  is there
lrwxrwxrwx  1 byers byers     39 Jan 20 09:39 .#rhjan09 -> by...@bo....3481:1231786181
