Re: BackupPC 4.0.0beta3 rsync_bpc "No such file or directory (2)"

So,

I managed to track down the issue. It *was* a configuration issue after
all. Given that my rsync -e arguments contained spaces (ie. ssh -i
/var/lib/backuppc/.ssh/id_rsa.pub -l backupper) I thought I had to properly
quote the arguments to make sure it was working correctly.

In the output this command seemed correct:

Running: /usr/local/bin/rsync_bpc --bpc-top-dir /mnt/backuppc/backups
--bpc-host-name <ip-address> --bpc-share-name / --bpc-bkup-num 0
--bpc-bkup-comp 3 --bpc-bkup-prevnum -1 --bpc-bkup-prevcomp -1
--bpc-bkup-inode0 1 --bpc-log-level 2 -e '/usr/bin/ssh  -o
UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no -i
/var/lib/backuppc/.ssh/id_rsa -l backupper' --rsync-path="sudo
/usr/bin/rsync" --super --recursive --protect-args --numeric-ids
--perms --owner --group -D --times --links --hard-links --delete
--partial --log-format="log: %o %i %B %8U,%8G %9l %f%L" --stats
--checksum --exclude=/tmp --exclude=/proc --exclude=/sys
--exclude=*.pem --exclude=id_rsa --exclude=.bash_history
--exclude=/var/logs --exclude=/usr/src --exclude=/opt/chef
<ip-address>:/ /

while in fact, it was using the following switch internally:

-e '/usr/bin/ssh\ \ -o\ UserKnownHostsFile=/dev/null\ -o\
StrictHostKeyChecking=no\ -i\ /var/lib/backuppc/.ssh/id_rsa\ -l\
backupper'

This obviously doesn’t work (escaping spaces + using quotes). This is also
the reason why c/p’ing the command as being logged and running it manually
*did* work, since the escaping wasn’t being shown in the log and thus
didn’t happen in my manual attempts.

So in conclusion:

1) BackupPC properly escapes spaces in arguments, so no need to put them in
quotes
2) BackupPC doesn’t log these escapes, so if you *did* put the arguments in
quotes, you won’t notice this unless you manually run ./bin/BackupPC_dump
-f -v <client-ip>

Now, one more thing I had to do was set UserCmdCheckStatus to 0, because
otherwise it would still exit, saying the pre-command returned -1, even
though it is set to undef in the configuration file.

Subversion Kills Productivity. Get off Subversion & Make the Move to Perforce.
With Perforce, you get hassle-free workflows. Merge that actually works. 
Faster operations. Version large binaries.  Built-in WAN optimization and the
freedom to use Git, Perforce or both. Make the move to Perforce.
