Re: [BackupPC-users] RsyncClientCmd --> RsyncSshArgs

[Mike H. <mi...@vi...>]

Hi BackupPC users,

Just curious if anyone else has made the changes necessary to use a non-root user account in the 4.X versions and run into any difficulty with incomplete backups?

Thank you!

Subject: RsyncClientCmd --> RsyncSshArgs

Transitioning from BPC 3.x to 4.x there seem to be some syntactic changes regarding rsync & ssh commands. I was able to follow documentation that I think lived on SourceForge where it was suggested to configure a non-root account for ssh'ing and running rsync under sudo. After some experimentation (and as I recall some frustration around "$argList" vs "$argList+") I came up with the following which worked great in version 3.3:

RsyncClientPath: --> /usr/bin/rsync
RsyncClientCmd: --> $sshPath -q -x -l backuppc $host sudo $rsyncPath $argList+
RsyncClientRestoreCmd: --> $sshPath -q -x -l backuppc $host sudo $rsyncPath $argList+

I think the only change I made to Rsync[Restore]Args was to add --checksum-seed=32761

Now in ver 4.2.1 the variables have changed. This is what I'm able to make work so far:

RsyncBackupPCPath: --> /usr/bin/rsync_bpc
RsyncClientPath: --> sudo /usr/bin/rsync
RsyncSshArgs: --> -e
--> $sshPath -l backuppc

However something is definitely off because the backup is incomplete. Many files and folders are missing. The most obvious is /home folder:
[cid:image001.jpg@01D432E3.351E9A30]
[caption - the home folder is empty - contains zero users!]

This is the only reference to "home" in my exclusion list:

    '/home/windows',

because I want to skip a folder named /home/windows.

Any help appreciated. Since I saw previous requests for this info here is my redacted XferErr from the latest run. I also tried removing --protect-args from RsyncArgs and added charset = utf-8 to the client's /etc/rsyncd.conf and restarted the service):
