Well, now this is getting fun.

The lsof manpage is indeed terrible, a wasteland of badly-organised
information and errata. A pox on its author and his pets. Most damning,
lsof cannot filter by file type AND user. So we use grep:

lsof -n -u backuppc | egrep ' (REG|DIR) ' |
   egrep -v ' (mem|txt|cwd|rtd) ' | awk '{print $9}'

In my tests, this lists open files used by the BackupPC processes. When
idle, this shows only logs:

/var/local/backuppc/log/LOG
/var/local/backuppc/log/LOG
/var/local/backuppc/log/LOG

When a restore is running, it also lists what files are currently being
read:

/var/local/backuppc/pc/host.example.com/431/f%
2f/fhome/fusername//ftemp_867333d87c32735ce70762d2dc7fca2a

You could filter out the logs too:

lsof -n -u backuppc | egrep ' (REG|DIR) ' |
   egrep -v '( (mem|txt|cwd|rtd) |/LOG)' | awk '{print $9}'

You could do a similiar thing on the client:

lsof -n -c rsync | egrep ' (REG|DIR) ' |
   egrep -v '( (mem|txt|cwd|rtd) |/LOG)' | awk '{print $9}'
