Backup Central

Where could I add a line to send a netbios/smb message to a workstation when a
backup is about to start? The line would be something like:

"Your machine is now being backed up..blah blah" | smbclient -M $host -
U "BackupPC" >> /dev/null

Any ideas? I thought it may be help on a machine by machine bases to allow
this as an option. Just another way let users know when a backup starts (and
stops).

Thanks,

Paul

See $Conf{DumpPreUserCmd}. Note that BackupPC doesn't execute commands
with /bin/sh (it calls exec() directly since the security is better).
Therefore, pipes and redirects won't work inside $Conf{DumpPreUserCmd}
(unless you add /bin/sh -c to the front of your command, and do
some tricky quoting).

Instead, put your commands in a short shell script, and point
$Conf{DumpPreUserCmd} to your script.

Thanks for the quick feed back. I create a sh script with:
echo "This is a TEST"|smbclient -U "BackupPC" -M TYRANT >>/dev/null

and in my main config.pl:
$Conf{DumpPreUserCmd} = '/usr/local/backuppc/smbnetsend';

This still does not seem to send the message, although it works from the
shell.. I am a little puzzled. Should this not send a message to the same
machine every time a backup starts?

Thanks,

Paul

I forgot to show the log:
Executing DumpPreUserCmd: /usr/local/backuppc/smbnetsend
Exec of /usr/local/backuppc/smbnetsend failed

The smbnetsend has the user rights of BackupPC.. Does this info help?

Yes, it should. Perhaps the backuppc user doesn't have a path
setting that includes smbclient? You should remove the ">> /dev/null"
and see what errors/output are in the XferLog file - any output from
the Pre/Post commands goes there. Also, does your script start with
an explicit path such as:

#!/bin/csh -f

Finally, you might want to change it so the host name gets passed to
the script:

$Conf{DumpPreUserCmd} = '/usr/local/backuppc/smbnetsend $host';

and then use $1 (first argument) in your script to get the hostname.

That did the trick! BackupPC is an amazing tool! I add the $host also..
works like a dream..

Thanks for the help.

This is excellent! However, I am experiencing a small problem with the
following setup:

$Conf{DumpPreUserCmd} = '/usr/local/backuppc/smbnetsend $host $type';

smbnetsend:

#!/bin/bash
echo "A $2 backup of your pc has been started..."|/usr/bin/smbclient -M
BackupPC $1

For some reason, the popup message received is:

"The DumpPreUserCmd backup of your pc has been started..."

Did I miss something?

Mike
