Sorry, there's no clean, portable way to have both multiple command-line
arguments in a single variable and have an IFS character in one of those
arguments.
When you do this rdiff-backup gets these arguments:
argv = {
[0] = "rdiff-backup"
[1] = "--remote-schema"
[2] = "'ssh"
[3] = "-i"
[4] = "/root/.ssh/id_backup"
[5] = "-C"
... /* etc. */
}
If you force your script to be executed with bash (NOT dash or just sh) you
can use shell arrays to do what you want:
RDSCHM=(
'--remote-schema'
'ssh -i /root/.ssh/id_backup -C %s rdiff-backup --server'
)
rdiff-backup \
"$RDSCHM[@]" \
$RDRM \
"$DEST/"
You can also force your to work correctly under dash / sh, but you'll have to
understand how to use eval, which can get a bit tricky. It would look
something like this:
RDSCHM="--remote-schema \
'ssh -i /root/.ssh/id_backup -C %s rdiff-backup --server'"
eval "rdiff-backup $RDSCHM $RDRM "'"$DEST/"'
