Backup Central

Hello...

I was just after some information regarding $Conf{DumpPostUserCmd} variable - When this is set, is it true that while this other external command is running, that BackupPC also still shows up in the cgi interface that it's still backing up?

I am running a command after it's finished ('/usr/bin/sudo /bin/sh /usr/local/scripts/scan-host.sh $host $type $xferOK') which scans for viruses of that host. Then after that is finished, it passes those variables to a perl script which mails the status to me (weather it was successful, plus virus summery information). But I've noticed that the the backup has finished as it's started to run the scan-host.sh script but BackupPC is reporting that it's still backing up the host (and I know it's not, as there is no bandwidth being chewed up). In the LOG file, it doesn't say that it has finished either.

Is this just normal? And if so, how can I get BackupPC to stop after it's finished backing up but continue to run the post command? Normally I wouldn't care but sometimes scanning for viruses can take a fair while, and if I was to stop it, I guess BackupPC would think this has failed and would then remove the 'new' directory and all the files in it that it creates when starting a new backup...

$Conf{DumpPostUserCmd} is run by BackupPC_dump after the Xfer
is finished, but before the backup is renamed and BackupPC
itself is told that it is done. Therefore it appears just
like you describe: while $Conf{DumpPostUserCmd} runs, BackupPC
will still show that the backup is running.

How about you background the script in $Conf{DumpPostUserCmd}?
However, BackupPC doesn't use a shell to run $Conf{DumpPostUserCmd},
so you can't just put an "&" at the end. But your script scan-host.sh
could background most of its work, then $Conf{DumpPostUserCmd} will
complete quickly and allow BackupPC_dump to finish up.

Thanks! I'll give it a go.

Hey gday, I finally got around to trying this... But it doesn't seem to =
be working properly. This the $Conf{DumpPostUserCmd} variable:

$Conf{DumpPostUserCmd} =3D '/usr/bin/sudo /bin/sh =
/usr/local/scripts/pass-values.sh $host $xferOK';

and in pass-values.sh, I have the following:

#!/bin/bash

## Few comments...

HOST=3D$1
XFER=3D$2

if [ $XFER =3D=3D 1 ]=20
then
/usr/local/scripts/scan-host.sh $HOST $XFER &
else
/usr/local/scripts/mail-backup.pl $HOST $XFER &
fi =20
sleep 5

(I have a sleep there so the scan-host.sh script scans the "new" =
directory before BackupPC_dump renames new to a number...)

Anyway, it still seems to be waiting for scan-host.sh to finish.

Also, is there a way to tell which file BackupPC is currently backing =
up? One of our hosts failed last night with ALM signal, possibly timeout =
issue, not sure, could be something else, just was wondering if there =
was a way thats all.

Thanks.

I don't have time to experiment or try to replicate this.
I'm not sure if BackupPC_dump is waiting on the background
process to complete. If so, you might try this:

if [ $XFER == 1 ]
then
nohup /usr/local/scripts/scan-host.sh $HOST $XFER &
else
nohup /usr/local/scripts/mail-backup.pl $HOST $XFER &
fi
sleep 5

(I have a sleep there so the scan-host.sh script scans the "new"
directory before BackupPC_dump renames new to a number...)

It better be fast: how can you be sure it runs fast enough?

Also, is there a way to tell which file BackupPC is currently backing
up? One of our hosts failed last night with ALM signal, possibly timeout
issue, not sure, could be something else, just was wondering if there

Look at the XferLOG.bad file.

Sorry Craig! I didn't think about this. Of course backuppc will try and
move the dir from new to the number while it's still scanning! I'll just
let it be. I'm only scanning the 'new' dir anyway which would take
bugger all time anyway (longer than 5 seconds though hehe). Don't think
backgrounding it with nohup will work but I'm not even going to bother
anymore.

Also, is there a way to tell which file BackupPC is currently backing
up? One of our hosts failed last night with ALM signal, possibly timeout
issue, not sure, could be something else, just was wondering if there
