1.
Everything is under one "/" filesystem.

2.
When I run this:
# rsync -av --delete /apps50/backup/./home/ape/ /backup01/ape.5.20040702010001/

I got this. Please note the error at the end. The target directory
contains the old backup 1 week ago, it is refreshed with the current
files.

3. Do I have enough space?

# du -sk /apps50/backup/./home/ape/ /backup01/ape.5.20040702010001/
2919456 /apps50/backup/./home/ape
2348284 /backup01/ape.5.20040702010001

# df -k .
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/hda3             37262796  26873832   8496108  76% /

So I have enough space.

4.
However, if I delete all files from the destination directory:

# cd /backup01/ape.5.20040702010001
# ls
apps01
# \rm -rf apps01/

And rerun the command. It is fine:

...
wrote 2907157423 bytes  read 534660 bytes  4568251.51 bytes/sec
total size is 2905200920  speedup is 1.00

This happened twice. The process is run on daily basis. I am sure it will 
happen again. So whatever debugging commands that I need to run, I can. Thanks 
a lot.
