Hi Craig,
No, there is no other process writing these files.
I launch the precopy script at prompt and it doesn't return control
until the whole process is finished, so no backgrounding there.
The only idea I can think of is:
- precopy is launched for /home and finishes
- tar backup starts for /home
- precopy is launched for /srv/www in parallel with tar backup of /home
That would explain that it doesn't happen always as it would depend on
the speed of both processes overlapping.
Is this scenario possible?
Thanks, Joe

BTW: Congratulations, I think you are doing an incredible job with the
product and your work on this list.
