I had backing up to localhost working under Backuppc V3.x.x. by setting
RsyncClientCmd to:
/usr/bin/sudo $rsyncPath $argList+
and adding a line to visudo:
backuppc ALL=(root) NOPASSWD:/usr/bin/rsync
which resulted in a command like this.
full backup started for directory / (baseline backup #397)
Running: /usr/bin/sudo /usr/bin/rsync --server --sender --numeric-ids --perms
--owner --group -D --links --hard-links --times --block-size=2048 --recursive
--ignore-times . /
Xfer PIDs are now 13562
Got remote protocol 31
Negotiated protocol version 28
Sent exclude: /var/lib/backuppc
Sent exclude: /sys/*
Sent exclude: /proc/*
Sent exclude: /dev/*
For v4 I've:
- added a similar line to visudo for /usr/local/bin/rsync_bpc
- set RsyncClientPath to sudo /usr/bin/rsync
Which fails due to root permission being denied (I think). The last bad
XferLog says

This is the rsync child about to exec /usr/local/bin/rsync_bpc
root@localhost: Permission denied (publickey,password).
So it doesn't seem to be running usr/local/bin/rsync_bpc as root.
RsyncClientPath doesn't have the same effect here as RsyncClientCmd did under
V3.x.x. Is this the problem and how might I resolve it, thanks?
