[flexbackup-help] file not found while backing up remote machine

[brian <bs...@ua...>]

I'm trying to back up a remote machine over SSH. The set is "xxx:/". The
prune for "xxx:/" is "tmp sys mnt proc dev".

When I test the configuration with -type filelist, I get

ERROR: non-zero exit from:
ssh xxx cd "/" && find . -regex
"\./\(lost\+found\|sys\|proc\|dev\|mnt\|tmp\)/.*" -prune -o -xdev ! -type
s ! -regex ".*/[Cc]ache/.*" ! -regex
".*~"$ -print > /tmp/27977/filelist.27977; cat /tmp/27977/filelist.27977
1>&2; cat /tmp/27977/filelist.27977 | gzip -4; x=(${PIPESTATUS[@]}); i=0;
while [ $i -lt ${#x[@]} ]; do [ ${x[$i]} -eq 0 ] || exit ${x[$i]};
i=$(($i+1)); done

The error was

bash: line 1: /tmp/27977/filelist.27977: No such file or directory
cat: /tmp/27977/filelist.27977: No such file or directory
cat: /tmp/27977/filelist.27977: No such file or directory
0+1 records in
0+1 records out

It looks like flexbackup created a directory in the local /tmp and then
tried to redirect some output on the remote machine to a nonexistent
directory in the remote /tmp. Am I making some mistake?
