Re: [BackupPC-users] Only v0 showing in backup history
OK, another update which may help people. I submitted an issue with bindfs (http://code.google.com/p/bindfs/issues/detail?id=20). Turns out there are some options to use with bindfs relating to inodes (actually they are FUSE options 'use_ino' and 'readdir_ino' but see issue above). These options are on by default in more recent versions of bindfs than I'm currently running.

By way of background, our backup setup is as follows: - Linux BackupPC server on ESX - Backup media on cheap SAN mounted via NFS - BackupPC directory remounted using bindfs (http://code.google.com/p/bindfs/) to get the user/group as backuppc The problem (only v0 showing) is occurring as a result of readdirent (from IO::Dirent) returning the value 4294967295 for all inodes - DirHistory detects v0, v1, etc buy looking for updated inodes on the backed up files. The problem only seems to occur for me only on the bindfs filesystem. I have attached a test program which I've used to confirm the problem.

[BackupPC-users] Only v0 showing in backup history
Hi, When browsing backups through the web interface (Directory backup history for directory page), the page only shows version 0 of all files. However, I can restore the different versions correctly via the command line tools. I am running version 3.2 of BackupPC. Any ideas?

Using aliases to ensure different BackupPC hosts actually alias to the
same network host.
/etc/backuppc/elvandar_crypto.pl:
$Conf{ClientNameAlias} = 'elvandar';
/etc/backuppc/elvandar_root.pl
$Conf{ClientNameAlias} = 'elvandar';

How did you configure this? I am looking to set up the same behavior.

Re: [BackupPC-users] rsyncd over ssh
Hi Jeffrey, At the risk of spamming the list again, I apologise. I only joined the list and the forum immediately before the post. And, I agree that I *thought* this is a topic-based forum rather than a mailing list - I went to www.backupcentral.com, selected the menu Forums and them Open Source BackupPC - it looked like a forum to me. Now I know :-) Anyway, the (mailing list) post I was referring to was http://www.backupcentral.com/phpBB2/two-way-mirrors-of-external-mailing-lists-3/backuppc-21/rsyncd-over-ssh-79117/ which relates to running BackupPC using rsync's daemon mode tunnelled over SSH. I've since got Joe's modifications which enable this and I'll let you know how I get on. FYI, the key issue for me is that I want to tunnel over SSH, but am not happy to allow un-checked root access to the target machine(s) - rsync's daemon mode tunnelled over SSH is a good balance.
